How this service works
One Bitcoin transaction with its fee rate and confirmation status — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok status, a type field ('btc-tx'), a payment receipt containing the tx_hash, amount_usd charged, and a receipt_id, plus a generated_at ISO8601 timestamp. The core Bitcoin transaction data includes fee rate and confirmation status for the queried txid.
Example use cases
Verify incoming Bitcoin payment
“I just received a payment — can you check Bitcoin txid f3a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1 and confirm it's been confirmed on-chain?”
Check BTC transaction fee after sending
“I just sent some Bitcoin and want to know the fee rate that was used — can you pull up the details for txid a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1?”
Monitor settlement of a high-value transfer
“We're waiting on a large BTC transfer to settle — please check txid 9f8e7d6c5b4a3f2e1d0c9b8a7f6e5d4c3b2a1f0e9d8c7b6a5f4e3d2c1b0a9f8e and tell me the confirmation status and fee rate.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/btc-tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-use lookup of a single Bitcoin transaction's fee rate and confirmation status without managing your own Bitcoin node or indexer. It's well-suited for agents that occasionally need to verify BTC payments or check transaction finality without a recurring subscription.
Side effects
- Invalid or malformed txid (not 64 hex characters) returns a validation error
- Transaction not found on Bitcoin network returns a not-found or null result
- Network timeout or upstream Bitcoin node unavailability
- Payment failure (insufficient USDC balance for x402 payment of $0.005)
