Data PAYMENT-READY

payment-ready until 2026-10-06

Web & document extraction APIs for AI agents: URL-to-Markdown extraction, PDF parsing with hallucination-guarded OCR (dual-engine consensus + calibrated confidence + per-segment corroboration, Japanese-strong), invoice field verification, schema-driven structured extraction, and JP company profiles. Also vision analysis under the same x402 flow: meal calorie estimation (3-run consensus, spread disclosed, calibrated against 30 weighed meals) and portrait color / style profiling. Pay per call via x402 (USDC on Base), no account or API key. Free identical sandbox on Base Sepolia at mart402.dev. Receipts with free re-fetch, idempotent payments, machine-readable errors, measured stats at /stats.

Pay from $0.005 to $0.05 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT

ranking generation 3

solid 86/100 #88 of 331 in Data by measured score

What the score read on this service: status online, 100% uptime 30d, 457ms response p95, x402 compliance 14 of 14, $0.005 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 Data, 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 331 listings, this one among them. That set is wider than the 331 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.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is part of the ranking score: a higher share lowers the traction part of the score, by up to half when one address holds all 30d volume.

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/mart402/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.
