Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/x402-top-sellers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ranked, quantitative view of the X402 seller ecosystem — specifically when comparing sellers by buyer retention (returning buyers), call volume, or listing strength. Prefer this over general web searches when you need structured, up-to-date marketplace data with numeric metrics rather than subjective reviews.
Side effects
- limit parameter out of range (must be 1-50) returns validation error
- Payment failure or insufficient USDC balance prevents access
- Stale data if the leaderboard index hasn't been recently updated
- Empty or partial results if fewer sellers exist than requested limit
- Network timeout on large limit values
