Inspect up to 10 public x402 endpoints in one paid request, without paying the t
Inspect up to 10 public x402 endpoints in one paid request, without paying the target endpoints. Returns per-endpoint quote status, schemes, amounts, network, asset, payTo, resource metadata, and aggregate buyer-readiness warnings. This deterministic endpoint does not call an upstream model. GET variant for agents, crawlers, and wallets that prefer query parameters over a JSON body. Pay up to $0.002 per request with x402 USDC on Base.
