U.S. federal contract search

Endpoint

Send the JSON body below. An unpaid request returns HTTP 402 with a PAYMENT-REQUIRED header; an x402-compatible buyer signs the requirement and retries with PAYMENT-SIGNATURE.

Official Coinbase agent path

Coinbase Agentic Wallet can satisfy this x402 request in one command. Running it may pay automatically, so --max-amount is fixed to $0.02 USDC in atomic units. Copying the command does not install, authenticate, sign, or pay; review the request and use a separate low-value wallet before running it.
