Two x402 endpoints on Base. /api/audit returns a deterministic technical audit of any product or landing page as JSON (1 USDC); /api/backtest runs a trading rule you POST as data, segmented out-of-sample against buy-and-hold, every fold reported including the losers (2 USDC). Both have free live samples. Settles EIP-3009 exact with no facilitator.
Pay from $1.00 to $5.00 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.

] OVER TIME
All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/pagecheck-page-audits-and-backtests-paid-in-usdc/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). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
Median across 3 endpoints. Use the selector to isolate one.
