OpenAPI/Swagger API Monitoring
Validate your APIs respect their documentation.
OpenAPI (formerly Swagger) is the standard for REST API documentation. But documentation doesn't guarantee the API follows it. Monitoring validates the API contract continuously.
Monitor your OpenAPI endpoints to detect breaking changes, schema regressions and compatibility issues before your clients do.
Why Monitor with OpenAPI
- Contract testing: validate API respects its documented specification.
- Breaking changes: detect incompatible changes before deployment.
- Documentation sync: ensure docs reflect reality.
What to Monitor
- Spec endpoint: monitor access to your openapi.json/yaml file.
- Response schemas: validate responses match defined schemas.
- Required fields: verify presence of required fields.
Automate with MoniTao
- JSON validation: use MoniTao assertions to validate expected fields.
- Multi-endpoints: create a monitor per critical endpoint in your spec.
Frequently Asked Questions
How to validate an OpenAPI schema?
MoniTao can check field presence and values. For complete validation, combine with CI tests.
Which OpenAPI version is supported?
MoniTao is agnostic - it monitors HTTP endpoints regardless of spec version.
How to detect breaking changes?
Monitor required fields with assertions. A missing field triggers an alert.
Can I monitor Swagger UI?
Yes, monitor your Swagger UI URL to ensure documentation remains accessible.
