# gpt55_x402_bazaar_search

Query the CDP x402 Bazaar discovery API, normalize paid resources, surface resource URL, service name, tags, scheme, network, payTo, and minimum USDC price. This deterministic endpoint does not call an upstream model. Pay up to $0.004 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised. Exact fixed-price payment and Base upto token-metered payment are both accepted when clients support them; upto settlements use actual response usage, a 0.0001 minimum, and the selected tier price as the cap.

The financial aspects describe payment mechanics (metering, pricing tiers) rather than the tool performing financial transactions itself. It reads/queries data without creating, modifying, or deleting resources.

From the tool's own definition: "Tool performs 'Query the CDP x402 Bazaar discovery API, normalize paid resources, surface resource URL, service name, tags, scheme, network, payTo, and minimum USDC price.' The description explicitly states 'This deterministic endpoint does not call an…"
