Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/combinerawtransactionWhen to prefer
Use this endpoint when you have multiple partially-signed raw Bitcoin transactions (from different co-signers in a multisig setup) and need to merge them into a single fully-signed transaction, without needing an API key — paying only $0.005 USDC per call via x402
Side effects
- Missing or malformed params array results in RPC error
- Transactions that do not share the same inputs/outputs cannot be combined and return an error
- Providing non-hex or invalid raw transaction strings returns a parse error
- Insufficient signatures to produce a fully valid transaction returns an incomplete result
- Payment of $0.005 USDC not fulfilled results in HTTP 402 rejection before RPC execution
