API Monitoring
Make sure your APIs always respond correctly
Your apps, partners and integrations depend on your APIs. Onagre continuously checks that they answer, answer fast, and return the data they should.
What Onagre watches for
- Is the API up and responding?
- Are response times acceptable?
- Does the response contain the expected values?
- Are authentication and access still working?
Sensors that power this
- HTTP response Free Availability and expected status codes of a URL, with method, headers, body and authentication.
- JSON content Free A value read from a JSON response and compared to what you expect.
- XML content Free A value selected with XPath and compared to what you expect.


HOW ONAGRE HELPS
Make sure the answer is right, not just present
An API can return a 200 and still be broken — wrong data, an empty list, a field that quietly changed. Onagre calls your endpoints on the schedule you set, checks the status code, measures how long the answer takes, and looks inside the response to confirm the values your apps depend on are really there.
Need to watch an API that only lives inside your network? A private agent runs the same checks from within your infrastructure — no port to open, no exposure to the outside.
- Status code and response-time checks on every call
- Read values straight from JSON or XML responses
- Compare results against the thresholds you expect
- Public or private — works wherever your API lives
