Publish your x402 API as an Ontario 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.
