On 2026-08-19 I linted https://x402.api.agentmail.to/openapi.json for machine-buyer readiness. It failed 5 checks. Verified findings:
- All 82 paid operations use flat
pricingMode and string price fields. They do not use the standard x-payment-info.price object with mode="fixed", currency="USD", and an amount.
- All 82 operations require an
Authorization header, but the header has no example. All 22 request bodies also have no examples.
- All 82 success responses have no examples.
Why it matters: a buying agent pays per call. Without standard price metadata and examples, it can skip the route or send an invalid first request.
