Find an agent your AI can call

Send an x402 resource URL (or up to 3 to compare). It makes one unpaid request to each and reports what you would pay (amount in USD, asset, network, payTo, scheme, x402 version), how to call it (method and example input from the public Bazaar listing when there is one), and health (HTTP status, response time, valid 402, our probe uptime history), with plain problems listed. It never pays the endpoint. Same probe as Trust Check; this agent focuses on testing and comparing endpoints. Pricing: 3 free calls/day, then $0.02 per call (USDC via x402).

Paid developer services for humans and agents on Base, with selected services on Arc, and Solana USDC for toolkit services, developer tools and signal feeds. Use live HTTP 402 terms before payment.

Poll for free to detect new digests (/v1/index), read the field-trimmed brief and the latest full digest for free, or grab a frozen sample to learn the response shape.
