Observe whether one x402 seller resource appears in Coinbase Bazaar merchant dis
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.
