An array of public addresses associated with the output of the previous transaction.For example, for bip65 on bitcoin, you could check its state via this URL:.Unique identifier for this job, used to get job status and results.

Optional Hex-encoded bytes of the transaction, as sent over the network.You can set it manually in the request object, useful if your source address is high-value, or you want to mitigate security risk after sending private keys.Documentation Please. cbitcoin is a bitcoin library in development designed to make developing bitcoin applications easier.Fee-based business models are thus easily achieved, and moreover, easily auditable via the blockchain.Metadata API: Store both public and private key-value pairs against addresses, transactions, and blocks.

Like normal wallets, it can be used interchangeably with all the Address API endpoints, and in many places that require addresses, like when Creating Transactions.Array of input data, which can be seen explicitly in the cURL example.Optional Raw size of block (including header and all transactions) in bytes.

Very similar to array of TXInput s, but with values related to assets instead of satoshis.

How to split your coins using Electrum in case of a fork

Since the default, non-registered rate limit per second is 3, larger batches require a paid API token.Optional Fixed processing fee amount to be sent to the fee address.

BTC-Crypt REST API Documentation. Existing Bitcoin Deposit Addresses.Start accepting bitcoin, store and spend bitcoin securely, or get the BitPay Card.The behavior part of our model primarily focuses on how a transaction propagates through the network.All endpoints that can retrieve a single Object can be batched to return multiple objects.As mentioned above, Bitcoin Testnet3 is frequently under attack, sometimes from core developers stress-testing the protocol, sometimes from malevolent actors attempting new attack vectors.Get live data on the Bitcoin exchange rate and live market price with our Bitcoin exchange rate API.

New blocks get built every minute, confirming the transactions that have been created using our transaction API.If successful, it will return the same Wallet or HDWallet object you requested, appended with your user token.In the mean time, if you want to experiment with client-side signing, consider using our signer tool.General information about a blockchain is available by GET-ing the base resource.PAYID is a string representing the payment forwarding request you want to delete, for example.

Optional Associated hex-encoded metadata with this transaction, if it exists.While reasonably unique, using hashes as identifiers may be unsafe.A TXRef object represents summarized data about a transaction input or output.Blockchain API: Endpoints to query general information about a blockchain and its blocks.

The returned object contains information about the address, including its balance in satoshis, the number of transactions associated with it, and the corresponding full transaction records in descending order by block height—and if multiple transactions associated with this address exist within the same block, by descending block index (position in block).Due to congestion on the Bitcoin network and the drastic increase in miner fees, data embedding has become uneconomical.Developer documentation and additional info. our Bitcoin Liquid Index API.Filters response to only include transactions below before height in the blockchain.Of course, all our API calls are standard HTTP endpoints using JSON formatted responses, so any language (or cURL from the command-line) will work just fine.Typically returned from the Unconfirmed Transactions and Transaction Hash endpoints.

The final destination address to which the payment will eventually be sent.Optional If not set, defaults to true, which means the API will wait for BlockCypher to guarantee the transaction, using our Confidence Factor.You are required to authenticate with your user token when using a Wallet or HD Wallet in any API endpoint.Our live block explorer visually shows confidence intervals on unconfirmed transactions directly.You can get a live view of unconfirmed transaction propagation analysis on Bitcoin by connecting to our Transaction Propagation WebSocket, at the following address.

We know many learn more from code examples than specific reference documentation, which is why we have code samples in our official languages.Bitcoin API setup guides, code examples, SDK downloads and documentation.A rolling average of the fee (in satoshis) paid per kilobyte for transactions to be confirmed in 7 or more blocks.

If successful, it will return an HTTP Status Code 204 with no return object.Optional All unconfirmed transaction inputs and outputs for this address.For more WebSocket implementation details, check Using WebSockets.MicroTXs can also be signed on the client-side without ever sending your private key.

Returns transactions relayed by a given source (IP address and port) within the given time range denoted by start and end.

When we started the Digital Currency Initiative (DCI) at MIT, our goal was to create an environment that enabled.Array of hex-encoded data for you to sign, one for each input.This set of endpoints currently leverages the Open Assets Protocol, a simple, robust method of embedding assets across any blockchain that supports null-data outputs.Array of bitcoin public addresses involved in the transaction.WebHooks leverage similar objects and interactions but with two key differences.But you can always see the full call in the cURL code sample.
