payment-ready until 2026-10-05
Xynaptic is a 151-endpoint pay-per-request data & AI API for autonomous agents — no API key, no signup, no subscription. One catalog covers: live crypto market data and quant analytics; worldwide company intelligence (French official registry, KYB, LEI international); US securities (fundamentals, technicals, filings, insider); banking/card utilities (statement parsing, IBAN/BIN validation, sanctions screening); French official real-estate transactions (DGFiP DVF registry, 915k+ sales, median EUR/m2, valuation, yield); health data (openFDA drug labels, ClinicalTrials.gov, PubMed, official French RPPS directory of 2.3M health professionals, HAS hospital registry); live commodities and industrial market data (Brent, copper, gas, gold, INSEE producer prices, supplier search/risk); an AI insurance suite (policy parsing, coverage verdicts, claim structuring, legal-basis quotes, ORIAS broker registry); energy (spot prices, forecasts, EV charge windows); transport (aviation events, flight status, SNCF real-time trains); AI verticals (web-search with sourced answers, company/finance/property agents); and ephemeral agent infrastructure (store, watch, prepaid tickets). Prices from $0.001 to $0.50 per request in USDC via x402 on Base, Solana or Polygon. Machine-readable catalogue at /health. Built for agents: uniform JSON schemas (schema_version 2), every response cites its data source and freshness, disclaimers on regulated content.
Pay from $0.005 to $0.03 per request in USDC on Base / Polygon, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT
ranking generation 3solid 87/100 #62 of 331 in Data by measured score
What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 141ms 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.
ALTERNATIVES IN DATA
Other Data 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).

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 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/xynaptic/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.
