How the score works

What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 479ms average response (no p95 yet), no gradeable x402 checklist (scored on the payment-ready prior), $0.005 price against the category. 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 Finance, 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 144 listings, this one among them: the same 144 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.

All measured facts

What it does

Exchange-exact crypto derivatives data for AI agents: open interest, funding and liquidations on 13 venues, measured Hyperliquid and Lighter positions with liquidation prices. Paid per call in USDC on Base or Arbitrum: rows of history and positions ($0.005), and answers priced by what they save an agent: a trading rule tested against the hourly archive ($0.10), hours that resembled now with their outcomes ($0.05), your liquidation price on 12 venues from their real maintenance-margin tiers ($0.02), an Ed25519-signed receipt of a data snapshot ($0.05). One payment to /api/v1/credits/buy returns a prepaid API key (no email). Conclusions and live snapshots are free; every number is checked against the exchanges every 10 minutes at /accuracy.

LiquidVision.app is a listed x402 Finance API. Captured payment terms name Arbitrum One, Base. 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.
