Publish your x402 API for agent discovery with an Ontario profile and Bazaar Launch Passport after free validation: public profile, readiness report, Coinbase indexing preflight, five-query buyer-intent audit, optional MCP procurement evidence, badge, distribution metadata, and 30 days of freshness maintenance. Call when you need public launch evidence. Ontario is not Coinbase. Payment buys processing and publication, not placement, ranking, buyers, or safety.

Caveats

Things to know before drawing strong conclusions

· Calls and volume are 30-day cumulative figures from the source facilitator. Daily breakdowns are not yet available — see /methodology.
· Volume = price × calls. If the server publishes multiple price tiers, only the first accepts[] entry is used.
· "Last call" is what the source last reported, refreshed every 60 seconds.
