Bitpost API

Bitpost API makes bitcoin transactions easier and cheaper for the end user. Server answers in JSend format.

API servers:

Note: new code is tried on testnet first, so it's less stable but might have new features not deployed on mainnet . Testnet can't simulate the fee environment on mainnet, in 99.99% of cases, 1 sat/B transactions will be confirmed.

Parameters

Name In Type Required Description
target query number true Unix epoch timestamp determining when the transactions should be executed (have at least one confirmation).
wallettoken query string false Optional string identifying the wallet who is creating the request. Should contain at least 20 characters.
changepos query integer false Index of the change address output of the transaction (starting with 0). This information can be retrieved later to make child transactions with the /getutxos endpoint. If absent, the change address will be deduced as the the output from which the fee is subtracted. To turn this off, set this parameter to a negative number.
delay query string false Delays broadcasting any transaction until the specified timestamp, thus scheduling payments into the future. Can be set to 1, to allow the application to delay the initial broadcast as it deems fit. Setting it to 0 forces a transaction to be initially broadcasted.
broadcast query string false TxID of the transaction tha was broadcasted or is intended to be broadcasted initially. Our servers will immedialty (re)broadcast this transaction. An index (starting from 0) of body of the request where the raw transaction is present is also accepted.
body body PSTarray or PSTjson true Array of raw signed transactions that signal for RBF with different fees.

Parameters

Name In Type Required Description
maxfeerate query number true the maximum feerate the owner is willing to pay in satoshis/byte.
size query integer false the number of feerates in the set. It should be no greater than maxfeerate, otherwise it will be adjusted.
canreducefee query boolean false whether or not the fee of the transaction can be reduced. This can happen if the transaction spends from a pending RBF transaction or the first transaction broadcast can be delayed.
target query number false Unix epoch timestamp determining when the payment should be executed (have at least one confirmation). This parameter is required if 'canreducefee' is set to false.
