How the score works
What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 105ms response p95, x402 compliance 14 of 14, $0.001 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 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 492 listings, this one among them: the same 492 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
Pay-per-call utilities for AI agents over x402, USDC on Base. No accounts or API keys. 56 REST endpoints and 50 MCP tools covering email checks, PDF and document extraction, web reading, currency and time, weather, SEC filings, paper search, and related jobs. Call unpaid, receive HTTP 402, pay, retry with PAYMENT-SIGNATURE. Failed calls are not charged.
Agent Tools is a listed x402 Data API. Captured payment terms name 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.
