Example prompt: What are the top-ranked x402 services right now based on real 30-day usage — show me the highest-demand ones with their scores and the snapshot receipt so I can verify the data.

## When to prefer this

Choose this endpoint when you need verifiable, scored discovery of x402 services ranked by real-world usage (30-day calls and paying wallets) rather than static or self-reported listings. It is especially useful when you want a receipted snapshot for auditability or when searching for a specific x402 service by partial URL match.

## Known failure modes

- Invalid or unrecognized URL substring returns empty result set
- Missing required 'type' or 'method' fields in input object returns validation error
- Service index may be stale if snapshot was not recently refreshed
- Non-GET/HEAD method enum value causes schema validation failure
- Network or worker timeout if index is large and query is broad

## Output

A JSON response containing ranked x402 service entries scored by 30-day call counts and paying-wallet bounds, a generatedAt ISO-8601 timestamp, and a receipt identifying the snapshot hash and scoring revision used.
