How the score works
What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 58ms response p95, x402 compliance 14 of 14, $0.012 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
44 SEO and keyword data endpoints for agents and developers, paid per call over x402 (USDC on Base), $0.012 to $0.25. Google search volume, CPC, keyword difficulty, keyword ideas and Google Trends; domain overview, ranked keywords, competitors and keyword gap; backlinks, referring domains and anchors; Google, Bing, YouTube, Maps and Amazon search results; on-page audit, PageSpeed, tech stack and brand mentions. Also as remote MCP and A2A. No account, no API key.
SEO and Keyword Data API 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.
