Api Endpoint

Agent Mercantile

Observe whether one x402 seller resource appears in Coinbase Bazaar merchant discovery and where the exact resource sits in the first 20 results for 1–3 buyer-supplied job-language searches. Factual evidence only. Call when you need a point-in-time Bazaar presence and top-20 search observation, not a trust, SEO, or remediation score.
