Uptime check, website status: is it up and how fast

$0.01 per call · failed calls are never charged · no account or API key needed

Check whether a website is up right now: one live request (following redirects) with the HTTP status, up or down, response time in ms, the final URL, content type, server header and page size, and optionally whether the page contains a given text. Timeouts and connection failures come back as down with the reason, not as an error. Use for uptime monitoring, health checks before calling an API, or to confirm a deploy.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/url/uptime?url=https%3A%2F%2Fwww.wikipedia.org%2F"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/url/uptime?url=https%3A%2F%2Fwww.wikipedia.org%2F&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
