OpenTestData API
REST API behind opentestdata.org, test.ai's free and open database of automated test fixture data. 13 paths / 16 operations covering user signup and login, e-mail confirmation, avatars, admin promotion, test and datum create/read/update, and a combined search over tests and data. Authenticated with a JWT bearer token. The publicly hosted instance the provider documented, api.opentestdata.org, no longer resolves; the contract survives in the company's own repository.
