How the score works

What the score read on this service: status online, 100% uptime 30d, 197ms 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.

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.

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 362 listings, this one among them: the same 362 the position above is counted against. When the two differ, the field is the wider one, 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.

Settled via coinbase ($18.00, 583 tx). Traction is a conservative undercount; first settlement seen 2026-09-22.

What it does

Xynaptic is a 200-endpoint pay-per-request data & AI API for autonomous agents · no API key, no signup, no subscription. Live crypto market data, quant analytics, wallet screening and pre-purchase token audits; French company intelligence (official registry, KYB, LEI); US & EU securities; banking/card utilities (IBAN/BIN validation, sanctions screening, payment risk, supplier compliance, used-car dealer check); French jobs (live France Travail offers, BMO recruitment tensions); official real-estate transactions (DGFiP DVF); health data (openFDA, ClinicalTrials.gov, PubMed, French RPPS); energy (RTE live demand, ENTSO-E spot prices, EV charge windows, battery arbitrage); commodities and industrial prices; transport (FAA NOTAMs, SNCF real-time); plus the first x402-paid agent SKILLS (SKILL.md methods chaining catalog services: supplier due diligence, payment fraud screening, crypto token audit). Prices from $0.001 to $0.50 per request in USDC via x402 on Base, Solana or Polygon.

Xynaptic is a listed x402 Data API. Captured payment terms name Base, Polygon. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.

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

Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.
