pagecheck — page audits and backtests, paid in USDC

payment-ready 2026-08-13, probe currently failing

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.

VERDICT

ranking generation 3

Not ranked yet: this listing was not in the ranked pool for AI the last time we built it, which happens at most once a minute. A service listed moments ago enters at the next rebuild.

ALTERNATIVES IN AI

Other AI services in this directory, ordered by the same measured score. The figures are ours: 30-day uptime from our own probes, 30-day settlement volume read on-chain (a conservative undercount, and null where we cannot measure it, never a zero).

ASSESSMENT

updated 3h ago

The parts the verdict above is computed from, each with its proof. Click any chip. Measured values stay read-only; unknown is honest, and an unknown is never counted as a zero.

uptime 90d: 85.9%

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (13/14): declares the current x402 version (2), stale (probe failing)

13 of 14 x402 conformance checks pass; failing: declares the current x402 version (2). Full checklist below.

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 use the 30d selector; each series spans only the dates it has data for. 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.
