How Signals work

Signals are scheduled change monitoring, billed per check. See what you can watch and how it’s priced.
This endpoint is a backward-compatible alias for POST /v1/signals/{id}/check-now. Prefer check-now in new integrations. For webhook plumbing without a scrape, use POST /v1/signals/{id}/test-webhook.
