Data Quality Gate

Verification PAYMENT-READY

payment-ready until 2026-10-02

Clean scraped data and assess data quality before an agent acts on it. Three POST endpoints, all deterministic and LLM-free: identical input always returns byte-identical output, so results are cacheable and replayable. POST /api ($0.01) - dataset quality verdict. Send a JSON array of rows; get a 0-100 score, a RELIABLE / USABLE_WITH_CLEANING / UNRELIABLE judgement, and exact per-check facts: completeness, nulls, type consistency, impossible values, exact and near duplicates, statistical outliers, cardinality. On financial data it also reports cross-source price divergence for the same asset. POST /api/clean ($0.04) - deterministic data cleaning. The response body IS the clean data: post a JSON array of row objects and the same array comes back repaired; post one object and one object comes back; post plain text and text comes back. CSV is accepted and returns parsed rows. Fixes broken encoding and mojibake ("Café" becomes "Café"), strips leftover HTML tags and entities, removes zero-width and invisible characters and non-breaking spaces, normalises whitespace. Repairs how data was encoded, never what it says: a negative price is reported, not rewritten. Flags failed extractions such as captcha walls and error pages instead of passing them off as content. POST /api/clean/audit ($0.12) - the same repaired data plus a reversible ledger of every transformation. Replaying it backwards reconstructs the exact input, byte for byte. Use it to clean scraped data, fix encoding, remove HTML from text, deduplicate rows, validate dataset contents, assess data quality, and decide whether to trust data before ingesting, indexing or trading on it. Never destroys a legitimate value: "None" stays a surname, "NA" stays Namibia, a Persian ZWNJ and an emoji joiner survive untouched. The full ruleset is published at GET /api/clean, readable before paying. Also a free Python library: pip install scrubkit.

Pay from $0.01 to $0.12 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT

ranking generation 3

solid 80/100 #67 of 100 in Verification by measured score

What the score read on this service: status online, 99.7% uptime 30d, 3180ms response p95, x402 compliance 14 of 14, $0.01 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

It is a score inside Verification, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 100 listings, this one among them. That set is wider than the 100 the position above is counted against, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

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.

Top buyer share is a concentration signal, not part of the ranking score.

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/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.
