How this service works
Bitcoin transaction by txid: confirmed or in the mempool, confirmations, block, fee in sats and sat/vB, RBF signal, inputs and outputs with addresses and amounts, USD value. Use to confirm a payment arrived or to check why a transaction is stuck.
Output
Returns whether the transaction is confirmed or still in the mempool, number of confirmations, the block it was included in, fee in satoshis and fee rate in sat/vB, whether RBF is signaled, a list of all inputs and outputs with addresses and amounts, and the current USD value of the transaction.
Example use cases
Confirm a customer Bitcoin payment
“A customer says they sent us Bitcoin with txid 7f3e2a1b9c8d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f — can you check if it's confirmed and how much they sent?”
Diagnose a stuck unconfirmed transaction
“My Bitcoin withdrawal has been pending for hours — the txid is 3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e. Can you check if it's in the mempool, what fee rate was used, and whether RBF is enabled so I know if it can be bumped?”
Audit a historical Bitcoin transfer
“I need to verify the details of an old Bitcoin transfer — txid 9f8e7d6c5b4a3f2e1d0c9b8a7f6e5d4c3b2a1f0e9d8c7b6a5f4e3d2c1b0a9f8e7d. Can you pull up the sender and receiver addresses, amounts, block it was mined in, and the USD value at settlement?”

Endpoint
POSThttps://agentsvc.io/api/v1/proxy/btc-tx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Bitcoin transaction status, including mempool visibility and RBF signaling, with fee analysis in both sat and sat/vB alongside live USD conversion — ideal for confirming payments, diagnosing stuck transactions, or auditing transfer details without running your own Bitcoin node.
Side effects
- Invalid or malformed txid (not 64 hex characters) — returns error
- Transaction not found in confirmed chain or mempool — returns not found
- Network timeout connecting to Bitcoin node — returns service error
- Transaction too old and pruned from accessible data — may return not found
