How this service works
chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. Build an m-of-n multisig address and redeem script from public keys. Bitcoin Core createmultisig.
Output
Returns a JSON object with the multisig address, the hex-encoded redeem script, and a descriptor string that can be used to reconstruct the script — mirroring the Bitcoin Core createmultisig RPC output.
Example use cases
Example prompt
“Create a 2-of-3 multisig Bitcoin address using these three compressed public keys: 0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798, 02c6047f9441ed7d6d3045406e95c07cd85c778e4b8cef3ca7abac09b95c709ee5, and 02f9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9.”
Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/createmultisigWhen to prefer
Choose this endpoint when you need to programmatically generate a Bitcoin multisig address and redeem script without managing a Bitcoin Core node or obtaining an API key — especially useful for custody, escrow, or shared-wallet workflows that need pay-per-call access billed in USDC.
Side effects
- Invalid or malformed public key causes RPC error
- m exceeds number of provided keys (e.g. 3-of-2)
- params JSON array is malformed or not properly URL-encoded
- Payment of $0.005 USDC not provided or insufficient — returns HTTP 402
- Bitcoin Core node unavailable — upstream RPC error
- Unsupported address type value causes parameter rejection
