How this service works
chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. Decode a PSBT into readable JSON: inputs, outputs, scripts, and metadata. Bitcoin Core decodepsbt.
Output
A JSON object containing the fully decoded PSBT: an array of inputs (each with UTXOs, scripts, witness items, BIP32 derivation info, partial signatures), an array of outputs (with scripts and derivation paths), an estimated fee, and top-level metadata such as version and locktime — mirroring Bitcoin Core's decodepsbt RPC response.
Example use cases
Example prompt
“Can you decode this PSBT for me and show me all the inputs, outputs, and scripts in plain JSON? The PSBT is: cHNidP8BAHUCAAAAASaBcTce3/KF6Tet7qSze3gADAVmy7utpLZD2xErGPkAAAA...”
Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/decodepsbtWhen to prefer
Use this endpoint when you need to inspect or audit a PSBT before signing or broadcasting — e.g. verifying inputs, outputs, and fee amounts in a multisig workflow. Prefer this over manual hex parsing when you need a structured JSON breakdown without running your own Bitcoin Core node. It requires no API key — just a micropayment via x402.
Side effects
- Invalid or malformed Base64 PSBT string returns an RPC error
- Missing required 'params' query parameter causes a bad request
- Payment of $0.005 USDC not fulfilled causes 402 Payment Required before the call is processed
- Non-PSBT data passed as param causes Bitcoin Core to return a parse error
- Network or node unavailability returns a 5xx error
