Paid x402 API from x402scan returning its ecosystem datasets: merchants, resources, buyers, facilitators and origin registry, priced per call in USDC on Base.
Pay from $0.01 to $0.02 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

risk clean
No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME
All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/x402scan/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
