Penny x402 Endpoint Audit
Fetch any public URL and report whether its HTTP 402 challenge is a schema-valid x402 v2 PaymentRequired, payable in Base USDC, and catalog-ready (Bazaar discovery declaration + facilitator support). Deterministic JSON verdict: reachability, HTTP status, schema validity, accepts/price/asset/payTo, and readiness reasons. No opinions, no LLM output.

Passing checks, but a short history so far. Treat as provisional.
On-chain payments
Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-10-11; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. Methodology.
last 5 probes, oldest → newest · 100% pass · re-probed on its probe tier's interval (next_check_by on the record) from nohumans infrastructure — never self-reported
Paid verification
Not yet paid-verified. Probe-based status above is liveness only.
