Skill: API contract drift check

agent402.tools · x402

The 'did this API contract change in a way that breaks our integration?' workflow. Diff two OpenAPI snapshots structurally, lint the new one for agent-readiness regressions, extract the endpoint surface for inventory comparison, validate a known-good payload against the new contract, and summarize security-relevant changes. Six tools, one go/no-go answer on whether the upstream API broke us.

x402: an unpaid request gets a 402 with the price and pay-to wallet. addrbook never pays.

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read . addrbook has not counted these payments itself.

Its x402 endpoints have not listed a payment option addrbook could read yet.
