Transaction

Get by Tx Hash

This endpoint retrieves the transaction details for a given transaction hash.

In the response body, if any output's hex size (vout[x].scriptPubKey.hex) exceeds 100KB, then the data for vout[x].scriptPubKey.hex and vout[x].scriptPubKey.asm is truncated and a flag vout[x].scriptPubKey.isTruncated is set to true.

For unconfirmed transactions, block and confirmations info won't be returned, as it doesn't exist.

A separate endpoint Get Raw Transaction Output Data can be used to fetch the full hex data, if required by the client application.

URL Parameters

Parameter
Description

hash

The hash/txId of the transaction to retrieve.

Get by Tx Index

This endpoint retrieves the transaction details for a given block height and transaction index in that block. Works only for confirmed transactions.

In the response body, if any output's hex size (vout[x].scriptPubKey.hex) exceeds 100KB, then the data for vout[x].scriptPubKey.hex and vout[x].scriptPubKey.asm is truncated and a flag vout[x].scriptPubKey.isTruncated is set to true.

A separate endpoint Get Raw Transaction Output Data can be used to fetch the full hex data, if required by the client application.

URL Parameters

Parameter

Get Transaction Propagation Status

This endpoint returns the propagation status for a given transaction. It queries a random set of peers on the network and returns the number of peers that have the transaction in question.

This is an expensive call, so it's recommended only for critical or high-value transactions that might require checking the network propagation status. It is rate-limited to 10 requests per 10 seconds.

If the transaction has been found on zero peers, possible reasons may include:

  • Propagation is still in progress;

  • The transaction fee rate, or that of a preceding transaction, is relatively low, making it invisible to peers that are configured to accept only higher fee rates.
