  • The median response time of the API is 206 ms .

Get p50 under 220 ms to get a 4/5 score.


The reliability score is derived from the number of inconsistent server responses, either server errors or non-conforming return values.

  • Self compliance: response objects matched the declared response types.
  • Server errors: the server did not return any 5xx error.


The design score reflects the quality of the specification file (usually named openapi.json or swagger.json). Having a high-quality specification file (with up-to-date types and examples) help developers understand the API and tools produce relevant documentation.

  • Respects OpenAPI 2.0 schema specification.
  • Contains comments and summaries.
  • Contains examples.
  • Does not contain duplicated objects.
