Frequently Asked Questions
What deprecation signals do you detect?
We parse Deprecation, Sunset, and Warning headers per RFC 8594, plus X-API-Warn, X-Deprecated-*, and response body patterns common across major API providers.
How quickly will I be alerted?
Endpoints are polled on your chosen interval (minimum 1 minute). Alerts fire within seconds of detection via email or webhook.
Can I monitor private or authenticated APIs?
Yes. You can store API keys and custom headers securely per endpoint. All credentials are encrypted at rest.
