Info

Latest Block Endpoint gives you detail information for the latest block in the blockchain

HTTP Request

GET /v1/bc/btc/${NETWORK}/blocks/latest

The returned object contains information about the latest block in JSON format, including its height, the number of transactions in it and more.

Addresses

Crypto APIs Address API allows you to generate single-use, low-value key pairs with corresponding addresses based on the coin/chain resource you’ve selected for your endpoints.

If you’re new to blockchains, you can think of public addresses as similar to bank account numbers in a traditional ledger. The biggest differences:

• Anyone can generate a public address themselves (through ECDSA in Bitcoin). No single authority is needed to generate new addresses; it’s just public-private key cryptography.
• Public addresses are significantly more lightweight. Consequently, and unlike traditional bank accounts, you can (and should!) generate new addresses for every transaction.
• Addresses can also leverage pay-to-script-hash, which means they can represent exotic things beyond a single private-public key pair; the most prominent example being multi-signature addresses that require n-of-m signatures to spend.

  }
}

Info

The default Address Endpoint strikes a general information about addresses. If you want to see the unconfirmed balance, set checkUnconfirmedbalance to true.

HTTP Request

GET /v1/bc/btc/${NETWORK}/address/${ADDRESS}?checkUnconfirmedBalance=true

Query Parameters

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)
ADDRESS	-------	Address in blockchain
checkUnconfirmedBalance	false	(boolean) returns unconfirmedBalance

ADDRESS is a string representing the public address (or wallet/HD wallet name) you’re interested in querying, for example:

1DBrYbe5U7LGDcHA5tiLCxivZ7JZAGqGhJ

or

mfd1JDV824jpfQkmhYaXtAZGULndSFYudT,mqvMWHkgYGkigx3wiZVhJVDbJhsEkkeKqM,n3WfwHYPuuiiyNK5oJ69Beq4qa2sdHniTV

The second type address is a multisignature address. Since multisignature addresses may be treated as common addresses the following query for the same results is possible:

GET /v1/bc/btc/testnet/address/mfd1JDV824jpfQkmhYaXtAZGULndSFYudT,mqvMWHkgYGkigx3wiZVhJVDbJhsEkkeKqM,n3WfwHYPuuiiyNK5oJ69Beq4qa2sdHniTV

{
  "payload": {
        "address": "mfd1JDV824jpfQkmhYaXtAZGULndSFYudT,mqvMWHkgYGkigx3wiZVhJVDbJhsEkkeKqM,n3WfwHYPuuiiyNK5oJ69Beq4qa2sdHniTV",
        "totalSpent": "0.0001",
        "totalReceived": "0.0001",
        "balance": "0",
        "txi": 1,
        "txo": 1,
        "txsCount": 2,
        "addresses": [
            "mfd1JDV824jpfQkmhYaXtAZGULndSFYudT",
            "mqvMWHkgYGkigx3wiZVhJVDbJhsEkkeKqM",
            "n3WfwHYPuuiiyNK5oJ69Beq4qa2sdHniTV"
        ]
  }
}

The returned object contains information about the address, including its balance in bitcoins and the number of transactions associated with it. The endpoint omits any detailed transaction information, but if that isn’t required by your application, then it’s the fastest and preferred way to get public address information.

Info

The Address Confirmed Transactions By Range Endpoint returns all information available about a particular address, including an array of complete transactions.

HTTP Request

GET /v1/bc/btc/${NETWORK}/address/${ADDRESS}/transactions-by-range/${FROM_TIMESTAMP}/${TO_TIMESTAMP}?index=0&limit=50/

Query Parameters

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)
ADDRESS	-------	Address in blockchain
FROM_TIMESTAMP	-------	From timestamp of desired txs
TO_TIMESTAMP	-------	To timestamp of desired txs
index	0	First index of returned txs
limit	50	Sets the number of returned txs

Meta Response

Variable	Type	Description
totalCount	int	Total count of the items in the listing for the given criteria
index	int	Sequential index number of the items list start position (depends on the skip parameter) for the given criteria
limit	int	Limit number of the items list (depends on the limit parameter) for the given criteria.
results	int	Count of the items listed in the current response for the given criteria

The default values of the query parameters index and limit are as follows: 0 and 50. FROM_TIMESTAMP and TO_TIMESTAMP must be provided to get transactions with date range. ADDRESS is a string representing the public address you’re interested in querying, for example:

Info

The Transaction Index by Block Endpoint returns detailed information about a list of transactions. The endpoint is useable both with block height and block hash. index and limit query parameters might also be used, as their default values are, as follows: 0, 1. Therefore, if none is specified the returned object will be the first transaction (the coinbase transaction) included in the block.

HTTP Request

GET /v1/bc/btc/${NETWORK}/txs/block/${BLOCK}?index=0&limit=1

Query Parameters

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)
BLOCK	-------	Block height or block hash in blockchain
index	0	index to start from
limit	1	number of transactions to be returned

Meta Response

Variable	Type	Description
totalCount	int	Total count of the items in the listing for the given criteria
index	int	Sequential index number of the items list start position (depends on the skip parameter) for the given criteria
limit	int	Limit number of the items list (depends on the limit parameter) for the given criteria.
results	int	Count of the items listed in the current response for the given criteria

BLOCK is a string or an integer representing the hash or the height of the block you’re interested in querying, for example:

00000000000000000008b7233b8abb1519d0a1bc6579e209955539c303f3e6b1

or

544704

The returned object contains information about the transaction in JSON format, including its block information, the total amount transacted with it (in bitcoins), the inputs and outputs, and more.

Info

The Get Raw Transaction Endpoint returns raw transaction hex about a given transaction based on its id.

HTTP Request

GET /v1/bc/btc/${NETWORK}/txs/raw/txid/${TXID}

Query Parameters

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)
TXID	-------	Id of the transaction in blockchain

TXID is a string representing the id of the transaction you’re interested in querying, for example:

0092e56ef024f79c76cbd9a55efb6e28a7ff22c950f65521e3b380f889c28d64

The returned object contains information about the transaction in JSON format, including its raw transaction hex.

HD Wallets

Hierarchical Deterministic (HD) Wallets

We also offer support for HD Wallets, which make it easy to manage multiple addresses under a single name. All HD wallet addresses are derived from a single seed. Please see BIP32 for more background on HD wallets.

HD Wallets can be created, deleted, and have new addresses generated. However, unlike normal Wallets, addresses cannot be removed.

When creating a wallet, one can optionally include one or more “subchain” indexes. These subchains can later be referenced when generating new addresses or sending txs. If none are provided in wallet creation, the wallet will derive & use addresses straight from the given extended pubkey. If no index is given when using the wallet with other APIs, it defaults to using the wallet’s first (sub) chain.

In BIP32 notation, the wallet layout is m/0, m/1, … and m/i/0, m/i/1, … for each subchain i if the wallet has subchains. For example, the path of the fourth address generated is m/3 for a non-subchain wallet. The path of the fourth address at subchain index two is m/2/3. Note that this is different from the default BIP32 wallet layout.

If you want to use BIP32 default wallet layout you can submit the extended public key of m/0’ (which can only be derived from your master private key) with subchain indexes = [0, 1]. Subchain index 0 represents the external chain (of account 0) and will discover all k keypairs that look like: m/0’/0/k. Subchain index 1 represents the internal chain (of account 0) and will discover all k keypairs in m/0’/1/k.

If you want to use BIP 44 layout (for BTC), you can submit the extended public key of m/44’/0’/0’. (which can only be derived from your master private key) with subchain indexes = [0, 1]. Subchain index 0 represents the external chain (of account 0) and will discover all k keypairs in m/44’/0’/0’/0/k. Subchain index 1 represents the internal chain (of account 0) and will discover all k keypairs in m/44’/0’/0’/1/k.

If an address ahead of current addresses listed in an HD Wallet receives a transaction, it will be added, along with any addresses between the new address and the last used one.

Using Hierarchical Deterministic (HD) Wallets

HD Wallets can be leveraged by the Address API, just by using their $NAME instead of $ADDRESS. They can also be used with Events and with the Transaction API. In general, using a wallet instead of an address in an API will have the effect of batching the set of addresses contained in the wallet

The following code examples should be considered serially; that is to say, the results will appear as if each API call were done sequentially. Also, $NAME is a string representing the name of your wallet, for example:

alice

NETWORK	-------	Network name (e.g. testnet or mainnet)

Request HD Wallet Object

{ "password" : ${ENCRYPTED_PASSWORD}, "walletName": ${HD_WALLET_NAME}, "privateKey": ${ADDRESS_PRIVATE_KEY}, "address": ${ADDRESS} }

This endpoint allows you to import a BTC address. Although it is only an address it will be treated as an HDwallet. Therefore, with the imported wallet users can make transactions and payment forwardings. Moreover, imported wallets can be listed and deleted.

Transactions

Crypto APIs Transaction API allows you to create and propagate your own transactions, including multisignature transactions, and embed data on the blockchain—all based on the coin/chain resource you’ve selected for your endpoints.

If you’re new to blockchains, the idea of transactions is relatively self-explanatory. Here’s what’s going on underneath the hood: a transaction takes previous “unspent transaction outputs” (also known as UTXOs) as “transaction inputs” and creates new “locking scripts” on those inputs such that they are “sent” to new addresses (to become new UTXOs). While most of these public addresses are reference points for single private keys that can “unlock” the newly created UTXOs, occasionally they are sent to more exotic addresses through pay-to-script-hash, typically multisignature addresses.

Generally speaking, UTXOs are generated from previous transactions (except for Coinbase inputs).

Prepare a Transaction

Info

Using Crypto APIs, you can push transactions to blockchains one of two ways:

Use our two-endpoint process outlined below, wherein we generate a TXSkeleton based on your input address, output address, and value to transfer. In either case, for security reasons, we never take possession of your private keys. We do use private keys with our Microtransaction API, but they are for low-value transactions and we discard them immediately from our servers’ memory.

To use Crypto APIs two-endpoint transaction creation tool, first you need to provide the input address(es), output address, and value to transfer (in bitcoin). Provide this in a partially-filled out TX request object.

HTTP Request

POST /v1/bc/btc/${NETWORK}/txs/create

Query Parameters

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)

As you can see from the code example, you only need to provide a single public address within the addresses array of both the input and output of your TX request object. You also need to fill in the value with the amount you’d like to transfer from one address to another.

Required fields are: { "inputs": [{ "address": "...", "value": ... }, ...], "outputs": [{ "address": "...", "value": ... }, ...], "fee": { "address": "...", "value": ... } }

Optional fields include: { "locktime": ..., "data": "...", "replaceable": false/true } You need to include data (string) field only if you want to send messages/metadata with the transaction. replaceable (boolean) field is only required if you want to allow the transaction to be replaced by a transaction with higher fees (e.g. if you set a low fee and miners are not picking the transaction up for a long period of time). By default replaceable is set to false. Locktime (integer) has a default value of zero. Use locktime if a transaction should be delayed to a specific time.

As a return object, you’ll receive a JSON containing a slightly-more complete TX alongside data you need to sign in the tosign array. You’ll need this object for the next steps of the transaction creation process.

Validating the Data to Sign

For the extra cautious, you can protect yourself from a potential malicious attack on Crypto APIs by validating the data we’re asking you to sign. Unfortunately, it’s impossible to do so directly, as pre-signed signature data is hashed twice using SHA256. To get around this, set the includeToSignTx URL flag to true. The optional tosign_tx array will be returned within the JSON, which you can use in the following way:

• Decoding the hex-encoded string using our /txs/decode endpoint (or an independent, client-side source) should give you the output addresses and amounts that match your work-in-progress transaction.

The Prepare, Sign and Broadcast a Transaction Endpoint combines the other three endpoints: Create, Sign and Send Endpoints. Users should provide the inputs and outputs fields with the corresponding data, as well as the fee and the wifs(private ECDSA keys) of the addresses. Therefore, the endpoint creates, signs and broadcasts the new transaction to the Bitcoin Blockchain. For more information, see the examples.

Users can set three optional fields within the createTx object: data, replaceable and locktime.

"createTx": { 
              "inputs": [ {
                "address": "...",
                "value": ...
              }],
              "outputs": [{
                "address": "...",
                "value": ...
              }],
              "fee":  {
                "address": "...",
                "value": ...
              },
              "locktime": ...,
              "data": "CRYPTOAPISROCKS",
              "replaceable": false/true
            }

You need to include data (string) field only if you want to send messages/metadata with the transaction. replaceable (boolean) field is only required if you want to allow the transaction to be replaced by a transaction with higher fees (e.g. if you set a low fee and miners are not picking the transaction up for a long period of time). By default replaceable is set to false. Locktime (integer) has a default value of zero. Use locktime if a transaction should be delayed to a specific time.

Prepare, Sign and Broadcast a Transaction Using HDWallet Endpoint provides the possibility to create, sign and send new transactions using your HDWallet. The mandatory fields are: walletName, password, outputs and fee (see example). There are a few optional fields, such as: inputs, fee address and locktime. If input addresses are not included, then the system will automatically choose addresses from the wallet. However, if included, a list of addresses from the wallet and the values should be specified. Fee address is optional and if is specified the fee will be proportionally distributed among the input addresses.

Three optional fields are available:

{
  "locktime": ...,
  "data": "...",
  "replaceable": false/true
}

You need to include data (string) field only if you want to send messages/metadata with the transaction. replaceable (boolean) field is only required if you want to allow the transaction to be replaced by a transaction with higher fees (e.g. if you set a low fee and miners are not picking the transaction up for a long period of time). By default replaceable is set to false. Locktime (integer) has a default value of zero. Use locktime if a transaction should be delayed to a specific time.

Info

We also offer the ability to decode raw transactions without sending propagating them to the network; perhaps you want to double-check another client library or confirm that another service is sending proper transactions.

HTTP Request

POST /v1/bc/btc/${NETWORK}/txs/decode

Request Object

{ "hex": "${HEX}" }

Query Parameters

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)
HEX	-------	hex of raw transaction

$HEX is a hex-encoded raw representation of your transaction, for example:

0200000005c1ab663c05cc557f522d55d42734eb3fe7bfacf3737cba5102233b312b0c95590000000000ffffffffbfd5dc9ac3129f2a9788d0ab2c201861790d66ce147bf6ebe8ee44019b69ed790100000000ffffffff2837839555246cc3f0f9374f73030341d641f3beae71eeafb2461f8ba8daa1d40000000000ffffffffbe23166dca2f0b9a24d9704e5e6ecfe3e57265cda29468e68c19644d24e1f1c70000000000ffffffff41994176b4bb3f00bb128a982b907e0a3b139ac02d90253c61815dea3d16f98d0000000000ffffffff0140420f00000000001976a9141a96349a5025735fe18f3e783098e471edbad83388ac00000000

If it succeeds, you’ll receive your decoded TX object.

The Refund a Transaction Endpoint allows users easily to return the amount in btc they have received from an unknown source. Only two fields are required: the txid of the transcation and the wif of the recipient address (see examples). There is an optional field fee. If fee field is not set the system will set the recommended fee from the Transaction Fee Endpoint.

HTTP Request

POST /v1/bc/btc/${NETWORK}/txs/refund

Query Parameters

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)

Transactions Fees

Every transaction on Blockchain has fee, the fee is not a fixed amount or % of the amount. The fee depends mainly on how much the network is overloaded. The higher fee you pay, the faster your transaction will be mined. You can use our different endpoints to get information all the time about fees and decide what fee you would set for your transactions.

Transaction Size

Info

Using Crypto APIs, you can calculate the approximate size of a standard transaction.

Required fields are: { "inputs": [{ "address": "...", "value": ... }, ...], "outputs": [{ "address": "...", "value": ... }, ...], "fee": { "address": "...", "value": ... } }

Optional fields include: { "locktime": ..., "data": "...", "replaceable": false/true }

Info

Transactions Fee Endpoint gives information about the fees for all transactions included in the last 70 blocks. min shows the lowest fee, max is the highest and average - the average fee. recommended is the fee that we consider as the one that corresponds to a cheap and fast execution. However, it is only a suggestion and should be used at users' sole discretion. average_bytes represents the average size of the transactions in bytes and is used for the calculations of the recommended fee price.

min_fee_per_byte, average_fee_per_byte and max_fee_per_byte represent the lowest, average and highest values per byte. slow_fee_per_byte, standard_fee_per_byte and fast_fee_per_byte represent the slowest, standard and fastest values per byte for a transaction fee. Crypto APIs provides an endpoint where you can get the size of your transaction in bytes. Using the provided data you can easily calculate and set your fee.

All fees are in btc!

Parameter	Default	Description
NETWORK	-------	Network name (e.g. testnet or mainnet)
estimateMode	CONSERVATIVE	The fee estimate mode. (“UNSET” “ECONOMICAL” “CONSERVATIVE”)
confTarget	1	Confirmation target in blocks (1 - 1008)

The returned object contains information about the estimated fee rate in BTC/kB and the block number where estimated fee value was found.

xPub, yPub, zPub

What is Xpub?

Every child key pair can define an xPub (Extended Public Key). As the name suggests, an Xpub doesn’t contain information about private keys, but only public ones. This means that an xPub will not give you access to the funds in a wallet, but the user can also view the child wallet’s addresses, transactions, and balances. You can think of it as a read-only view of a wallet.

What are Ypub and Zpub?

After the adoption of SegWit, theBIP49 standard gave origin to the yPub. A yPub key is the same as an xPub key. However, it follows the new standard and has an address type P2SH-P2WPKH. yPub is for backward-compatible SegWit Wallets.

After the xPub and yPub, the newest Public Extended Key is zPub. Just as its predecessor the zPub follows the BIP49 standard, but the address type is P2WPKH. zPub is for native compatible SegWit wallets.

Info

Get Pub Addresses Endpoint allows you to get addresses associated with the specified extended public key. Supported BIP formats are: bip39, bip44, bip49 and bip84. Since addresses are hierarchically ordered we provide the query params index and limit, in order to be able to get the addresses in specific positions. Default values are: 0 and 100, accordingly. The default values will return the first one hundred receive addresses. If you want to get the change addresses of the extended public key you should set type to be equal to "change" as a query parameter. If you want to get addresses in P2PKH (P2PKH which begin with the number 1, eg: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2) address format type you should set address_type to be equal to P2PKH. If you want to get addresses in P2SH (P2SH which begin with the number 3, eg: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy) address format type you should set address_type to be equal to P2SH. If you want to get addresses in Bech32 (Bech32 which begin with bc1, eg: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq) address format type you should set address_type to be equal to Bech32.

Info

Get Pub Addresses Endpoint allows you to get transactions associated with the specified extended public key. Supported BIP formats are: bip39, bip44, bip49 and bip84. Since addresses are hierarchically ordered we provide the query params index and limit, in order to be able to get the addresses and their transactions in specific positions. Default values are: 0 and 100, accordingly. The default values will return the transactions for the first one hundred receive addresses. If you want to get the change addresses of the extended public key you should set type to be equal to "change" as a query parameter. If the transactions you are looking for are transactions from addresses in P2PKH (P2PKH which begin with the number 1, eg: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2) address format type you should set address_type to be equal to P2PKH. If the transactions you are looking for are transactions from addresses in P2SH (P2SH which begin with the number 3, eg: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy) address format type you should set address_type to be equal to P2SH.

Info

Get Pub Details Endpoint allows you to get transactions associated with the specified extended public key and the total balance of the results. Supported BIP formats are: bip39, bip44, bip49 and bip84. Since addresses are hierarchically ordered we provide the query params index and limit, in order to be able to get the addresses and their transactions in specific positions. Default values are: 0 and 100, accordingly. The default values will return the transactions for the first one hundred receive addresses. If you want to get the change addresses of the extended public key you should set type to be equal to "change" as a query parameter. If you are looking for the details from addresses in P2PKH (P2PKH which begin with the number 1, eg: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2) address format type you should set address_type to be equal to P2PKH. If you are looking for the details from addresses in P2SH (P2SH which begin with the number 3, eg: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy) address format type you should set address_type to be equal to P2SH. If you are looking for the details from addresses in Bech32 (Bech32 which begin with bc1, eg: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq) address format type you should set address_type to be equal to Bech32. If you are looking for the details from addresses in ALL (P2PKH, P2SH, Bech32) formats type you should set address_type to be equal to ALL.

results property in the response shows the number of addresses that have transactions for the specified query.

Payment Forwarding

Payment Forwarding is an automatic way to move any received funds to another wallet, it's mainly used to move funds once received to cold wallets. Moving funds from hot wallets to cold wallets is a common practice in the market, it's used by all exchanges and wallets. You can subscribe for payment forwarding for any wallet/address you own, in the subscription you mention where to move the funds and how to notify you once done. Crypto APIs will monitor the wallet/address you have subscription for and once any funds are received, Crypto APIs will move them to the target wallet/address then notify you by sending a call to the URL you have specified. commerce without necessarily requiring extensive setup barriers, like registering new accounts. In that spirit, our Payment Forwarding API is the easiest way to accept—and consolidate—payments securely without forcing your users to create accounts and jump through unnecessary loops. It’s also a generic way to automatically transfer value from one address to another. One of the well-known benefits of cryptocurrency is the ability to allow users to partake in online commerce without necessarily requiring extensive setup barriers, like registering new accounts. In that spirit, our Payment Forwarding API is the easiest way to accept—and consolidate—payments securely without forcing your users to create accounts and jump through unnecessary loops. It’s also a generic way to automatically transfer value from one address to another. While there are many possible use cases, the two we hear most about are: A way to generate payment-specific addresses for which funds will automatically transfer to a main merchant address. Great for automatic merchandise (whether physical or virtual) processing.

We do not take a fee on payment forwarding, other than the required miner fee; payments are free. However, as part of your own services, you can include a fee (either fixed or a percentage) that will also be automatically transfered to your own address in the same transaction. Fee-based business models are thus easily achieved, and moreover, easily auditable via the blockchain.
