How this service works
chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. An unspent transaction output (UTXO) by txid and index from chainquery's independent full node. Bitcoin Core gettxout.
Output
Returns the Bitcoin Core gettxout result: UTXO value in BTC, scriptPubKey details (asm, hex, type, addresses), number of confirmations, the best block hash at query time, and a coinbase flag — or null if the output has been spent or does not exist.
Example use cases
Example prompt
“Is the output at index 0 of Bitcoin txid 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b still unspent? Pull the UTXO details from chainquery's Bitcoin node.”
Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/gettxoutWhen to prefer
Use this endpoint when you need to verify UTXO existence and details (value, script, confirmations) for a specific txid:vout pair from an independent full node, without setting up your own node or obtaining an API key — especially when pay-per-call micropayment access via x402 is acceptable and you need trustless, node-direct results rather than a third-party index.
Side effects
- txid not found or already spent returns null result
- malformed txid returns RPC error
- invalid vout index returns null
- params not JSON-encoded correctly returns 400 or RPC parse error
- payment failure (402) if x402 payment header is missing or insufficient
- node temporarily unavailable returns 5xx
