How this service works
Blockchain explorer gateway — Solana, Bitcoin, Bitcoin Cash, Ethereum
Output
Returns a JSON response containing detailed information about the queried Bitcoin transactions, including transaction status, confirmation count, block height, inputs, outputs, fees, amounts, and timestamps for each txid provided in the request.
Example use cases
Confirm received Bitcoin payment
“I need to verify that a Bitcoin payment I was expecting actually went through — can you check the status and confirmation count for this txid: 6f7cf9580f1c2dfb3c4d5d043cdbb128c640ffd621df703c63f4b8a0f7855f06?”
Audit batch of BTC transactions
“I have a list of 10 Bitcoin transaction IDs from last week's payouts — can you pull the details for all of them so I can reconcile them against our records? Here they are: [txid1, txid2, txid3, txid4, txid5, txid6, txid7, txid8, txid9, txid10].”
Investigate suspicious BTC transfer
“Someone claims they sent me Bitcoin two hours ago with this transaction hash: 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b — can you look it up on the blockchain explorer and tell me if it's confirmed and what the amount is?”
Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/btc/transactions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to look up one or more Bitcoin (BTC) transaction details by their transaction IDs directly from blockchain.com's explorer infrastructure. It supports batch lookups of up to 50 txids in a single call, making it efficient for reconciliation or audit tasks. Prefer this over generic block explorers when you need programmatic access with JSON output and are already integrated with x402 micropayment flows.
Side effects
- Invalid or malformed txid strings result in an error or empty response for that entry
- Exceeding 50 txIds per request returns a validation error
- Unconfirmed or very recent transactions may return incomplete data
- Network or upstream blockchain node issues may cause timeouts or 5xx errors
- Payment failure (insufficient USDC balance for x402 payment) blocks the request
