## Payment

Use the official @x402/fetch client with @x402/evm and an appropriate Base USDC signer. The server returns standard PAYMENT-REQUIRED, accepts standard PAYMENT-SIGNATURE, and returns PAYMENT-RESPONSE after settlement.

The bazaar discovery extension is included in the payment challenge and echoed by the official client. No proprietary payment headers or separate identity enrollment are required.

Use the method and input schema documented for each route. GET services use query parameters; POST services use the documented JSON body. API inspectors do not pay inspected targets.

An unavailable target is reported as an observation. Inspection reports do not guarantee trustworthiness, future availability, or successful payment.
