The paid-proof layer for x402 commerce

Proof of what happens after payment.

x402 lets software agents pay for API calls and web resources with stablecoins: the server quotes a price in an HTTP 402 response, the agent pays, and the resource returns. ResolveBots exists for the messy part: we buy endpoints with real USDC before you have to, publish what came back, and rank every service on one question: could an agent actually use the result?

We pay first Reviews start with real USDC calls, not scraped marketplace descriptions.
You see the payload before you pay Agents and builders can inspect sample payloads before they spend.
Failures stay public Timeouts, charged failures, stale metadata, and network gaps stay visible in the evidence trail.
Paid proof

Directories show what exists. ResolveBots shows what happened after payment.

x402 makes machine payments simple, and directories are getting better at showing what is live. ResolveBots handles the part directories cannot: independent paid evidence, response shape, failure visibility, and whether an agent could actually use the result.

Pilot pricing

Priced so sponsors can buy testing, never rankings.

The best price is the one that gets useful endpoints tested without letting sponsors buy the ranking. Pilot packages keep editorial scoring separate from paid placement.
