Audit Tools

Verification

Evaluate an Apify actor before you use it. Send one actor ID (for example apify/instagram-scraper) and get an evidence-backed quality report: 23 built-in criteria like reliability, 30-day failure rate, advertised-field truth, and cost per usable item, deep-scan criteria measured from live funded runs, or your own rubric in plain English. Use it to audit a scraper, compare actor quality, or pick the best actor. Returns JSON with per-criterion scores, evidence, and a verdict.

Pay from $1.00 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.

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/audit-tools/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.
