FIRST PUBLIC-PAGE CHECK
Start with one source.
Before monitoring a supplier changelog or public pricing page, check that FluxProof can read it. Try example.com to learn the request, then replace it with the public source you actually need.
No key, payment or monitor is created here. JavaScript-only pages, sign-in and bot challenges are not supported. This example does not demonstrate a change between observations.
Ready. Nothing has been fetched yet.
Your source is readable.
The response is metadata only. Monitoring requires a separate API key and explicit baseline creation. The free plan supports one daily source; faster schedules, history and webhooks require the $9 pass.
Choose free or paid access · Create your first monitor: copyable REST and MCP stepsReferral and flow labels are caller-supplied hints, not unique people. We record the step reached with a random flow ID; no page text is included in the preflight event.
