Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/converttopsbtWhen to prefer
Use this endpoint when you need a pay-per-call, no-API-key Bitcoin Core converttopsbt RPC call and want to avoid running your own node. Ideal for one-off PSBT conversion tasks in agent workflows, multisig coordination, or hardware wallet signing flows. Prefer this over self-hosted nodes when you want instant access without infrastructure overhead and are comfortable with per-call micropayment pricing via x402.
Side effects
- Invalid or malformed raw transaction hex returns an RPC error
- Transaction already has signatures and cannot be converted to PSBT
- Network or payment failure returns 402 if USDC payment is not attached
- Missing or malformed params JSON array returns a 400 error
- Non-final or invalid transaction structure rejected by Bitcoin Core
