Ontario Protocol.
Free provider check · no settlement

See whether paying agents can find your x402 endpoint across five searches.

Enter one real buyer task. Ontario tests five deterministic variations against live CDP Bazaar search, then separates retrieval coverage, objective quality observations, HTTP 402 readiness, and activation evidence.

What the audit covers

Five buyer searches

The exact task plus four deterministic variants, observed target rank, returned alternatives, and visible Base USDC prices.

Objective quality

Public CDP 30-day call, unique-payer, and recency fields. These can include owner-funded tests and are never presented as revenue.

Gap diagnosis

Separates implementation, activation, and semantic relevance gaps so an already-indexed provider is not sold another activation review.

What it does not prove

This free check does not make an endpoint appear in Coinbase Bazaar. Coinbase documents that Bazaar cataloging follows a successful settlement through the CDP Facilitator for a Bazaar-enabled route. Ontario does not perform that settlement, request private keys, verify external placement, or guarantee safety, traffic, ranking, revenue, or future behavior.
