Example prompt: Pull up the current x402 Bazaar rankings — I want to see which live x402 services are scoring highest based on real 30-day call volume and paying-wallet activity, including the snapshot hash for verification.

## When to prefer this

Choose this endpoint when you need a ranked, verifiable view of the live x402 service market based on real usage signals (30-day calls, paying wallets) rather than self-reported metadata. It is the right choice when you want an auditable snapshot receipt alongside discovery results, or when evaluating which x402 services have genuine traction before integrating or investing in them.

## Known failure modes

- No services indexed yet — empty data array returned
- Snapshot data stale if the indexer has not run recently
- Payment required error (402) if the $0.50 USDC call fee is not settled
- Schema mismatch if properties filter is malformed
- Rate limiting or worker timeout on Cloudflare edge

## Output
