Abstract: Disclosed embodiments provide techniques for monitoring application program interface (API) health based on design-time checks and runtime performance. The health of an API can include multiple factors. The factors may include correctness of the data returned/output by the API. A high amount of incorrect data may correlate to a lower health metric. A low amount of incorrect data may correlate to a higher health metric. If a health metric value falls below a predetermined threshold, it may indicate that the API health is poor, and hence, should not be used, or should be used with caution, depending on the application. In embodiments, an alternate API may be automatically selected as a replacement for an API in response to a health metric falling below a predetermined threshold.
