x402 trust check ($0.003 USDC). Use before you pay an unfamiliar x402 endpoint, or when choosing between paid APIs.

Use it before paying an unfamiliar x402 endpoint or when choosing between paid APIs. We send one unpaid request and report whether it returns a valid 402, the price, asset, network and payTo, response time, whether that matches its public Bazaar listing, and our probe history, with a 0-100 score and each factor spelled out. Measured by our probes; not a guarantee. Never charged for errors: we settle the payment only after a successful answer.
