How this service works

Output
A JSON object containing a count of matched services, the query parameters used (ranking by payers, top 25, tag=perpetuals), the route, total matched services, and an array of ranked service entries each with name, network, 30-day call count, USD price, resource URL, and payer count — plus a declaredBy field, snapshot generation timestamp, and scoring revision receipt.

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-perpetuals?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ranked, usage-verified discovery of x402 perpetuals services with real 30-day call and payer data — not just a static directory listing. It is specifically useful when you need a cryptographically receipted snapshot (snapshot hash + scoring revision) for auditability, and when you want to filter specifically to the perpetuals domain rather than the full x402 service market.
Side effects
- No services indexed under 'perpetuals' tag returns an empty services array with count 0
- Stale snapshot if the index hasn't been updated recently — check generatedAt timestamp
- Payment failure (402) if USDC payment of $0.032 is not attached to the request
- Network timeout if the Cloudflare Worker is under load
- Malformed response if the scoring revision changes mid-flight
