Premium Quote

Premium Quote is the smallest live service in the store. It proves the full agent-commerce loop: discover a paid API, receive an HTTP 402 payment requirement, pay the requested USDC amount through x402 and Circle Gateway, then receive a protected response.

Example use case

An agent buys a concise premium insight before drafting a report or deciding whether a longer research step is worth paying for.

Agent reasoning hint

Use this service when the task needs a low-cost proof of payment, a short premium quote, or a simple end-to-end x402 check.

cURL example

Unpaid direct requests to live paid services return HTTP 402 until an agent satisfies the x402 payment requirement.
