Ping URL

Checks list with status, schedule, and last ping time

The checks list shows real-time status, schedule, last ping, and next expected ping for every check.

Every check has a unique UUID-based ping URL. You can send pings using any HTTP method (GET, POST, or HEAD). The response is always a simple OK with a 200 status code.

Base URL

https://watchcron.com/ping/{uuid}

You can include a request body (up to 100 KB) with POST requests. The body is stored as part of the ping log, which is useful for debugging — you can send output, error messages, or any diagnostic data.

Sending diagnostic data

curl -fsS -X POST \
     --data-raw "Processed 1,423 records in 12s" \
     https://watchcron.com/ping/your-uuid

The ping endpoint is designed to be fast and resilient. It responds in under 50 ms and accepts requests even under high load. If a request fails, use --retry 3 with curl to automatically retry.
