Data Quality Gate
Verification ✓ VERIFIEDverified until 2026-08-18
Deterministic dataset-quality gate for AI agents. POST a JSON dataset, get back a RELIABLE / USABLE_WITH_CLEANING / UNRELIABLE verdict with exact, recomputable facts (completeness, nulls, types, impossible values, duplicates, outliers) and a 0-100 score -- no LLM, same input always produces the same output. On financial/trading data, also detects cross-source price divergence for the same asset (e.g. the same trading pair quoted very differently by two exchanges), reported as additional facts. Built to be called per-batch before a decision, not as a real-time/streaming feed.
Pay from $0.01 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

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

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.

REQUEST / RESPONSE EXAMPLE
An unpaid request to POST /api returns HTTP 402 with the payment terms. Settle onchain via your facilitator, then retry with the X-Payment header.

] OVER TIME
All charts use the 7d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/data-quality-gate/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.
