How this report is made

• Source: the public Coinbase CDP x402 Bazaar discovery catalogue, snapshotted in full about once a day.
• Buyers = unique paying wallets per listing in the last 30 days, as the Bazaar reports them; one wallet buying from several listings counts once per listing. Many listings show 1–2 buyers (often their own tests), so we also show listings with 5+ buyers.
• Uptime and speed = our own unpaid checks (one request, expecting a 402 price quote) several times a day for the most-used listings. We never pay or call other services beyond that check.
• MCP servers: the official MCP Registry (public domain), synced twice a day. Health = one plain request to each hosted server's URL several times a week; we never call its tools.
• Categories come from each listing's description and URL. Novelty and test endpoints (jokes, dice, pings) are excluded from rankings.
• Neutral: no paid placements. Aayat AI's own services are ranked by the same rules and mentioned only where they rank.
