Official indexing preflight
Coinbase's read-only validation result, required and advisory checks, simulated acceptance, and active-index status. Ontario discards raw payment material.
Free provider check · no settlement
See whether paying agents can find your x402 endpoint across five searches.
Enter one real buyer task. Ontario runs Coinbase's official read-only indexing preflight and five deterministic Bazaar searches, then separates configuration acceptance, index state, retrieval coverage, quality observations, and activation evidence.

Next justified step
Ontario recommends paid work only when the observed gap has a bounded deliverable.
No offer guarantees catalog ordering, traffic, safety, settlement, buyers, or revenue.
What the audit covers
Five buyer searches
The exact task plus four deterministic variants, observed target rank, returned alternatives, and visible Base USDC prices.
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.
