How the score works

What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 563ms response p95, x402 compliance 14 of 14, $0.003 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 462 listings, this one among them: the same 462 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

switch402 is a pay-per-call web scraping API for AI agents. We built it. Your agent sends one request to one endpoint and gets the page back as markdown. Behind it, switch402 picks a healthy x402 scrape provider from several verified ones, fails over to the next on error, and charges only on success: if every provider fails you get a 502 and pay nothing. $0.008 per successful call ($0.003 on /v1/scrape/lite), USDC on Base over x402. No signup, no API key, no monthly plan. Docs: https://api.switch402.com/llms.txt
