How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
A JSON object containing full details of the specified Bitcoin transaction, including transaction ID, block height, confirmation count, timestamp, total value transferred, fee, and the list of inputs and outputs with their addresses and amounts.
Example use cases
Verify incoming Bitcoin payment
“I'm expecting a Bitcoin payment from a customer — the transaction ID is f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16. Can you check whether it's confirmed and how much was sent?”
Audit on-chain transaction for accounting
“I need to audit a BTC transfer for our records. The transaction hash is a1075db55d416d3ca199f55b6084e2115b9345e16c5cf302fc80e9d5fbf5d48d — can you pull the full details including inputs, outputs, and fee?”
Debug a stuck or unconfirmed transaction
“My Bitcoin withdrawal seems stuck — the txId is 9021e8b4f2aa5e6e6a77a4d5b6e9b0f3c1d2a3e4f5a6b7c8d9e0f1a2b3c4d5e6. Can you check how many confirmations it has and whether it's been broadcast to the network?”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/btc/transaction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, real-time Bitcoin transaction data from blockchain.com's explorer infrastructure, especially for confirming payments, auditing transfers, or retrieving on-chain details by transaction hash. Prefer it over generalized blockchain APIs when you need reliable BTC-specific lookup with per-call micropayment pricing via x402.
Side effects
- Invalid or malformed txId returns an error response
- Transaction not found (e.g. not yet broadcast or wrong network) returns 404 or empty result
- Network timeout or upstream blockchain node unavailability
- Payment failure if USDC balance is insufficient for the $0.001 per-call fee
