Turn your OpenAPI spec into a monitoring plan

Paste your spec, get the 10 endpoints most worth monitoring, with per-endpoint Crontap deep links and suggested cadences.

How to pick a cadence

1 minute — infra health endpoints (/health, /ready). You want fast detection.
5-15 minutes — business-critical reads (/me, /users/{id}, /version).
60+ minutes — informational endpoints where rare failures are tolerable.

API health checks — use case companion.
Cron job monitoring — the monitoring product.
Synthetic monitoring — spec-driven monitoring patterns.
Curl explainer — sibling AI tool.

Ready to fix it?

Point Crontap at any URL. Pick any cron. Done.

WordPress, Shopify, Railway, Cloud Run, Vercel, HubSpot, Ghost, your own box. If it answers HTTP, Crontap can drive it on a clock you can read, in the timezone that actually matters, and page you when something breaks.
