REST API

The COCO Annotator API is organized around REST. The API has predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors. JSON is returned by all API responses, including errors.

A swagger interface can be found at localhost:5000/api which lists each endpoint and allows you to call it from your web browser.
