mockAPI

mockAPI.io is a hosted mock API service that lets developers create custom REST endpoints, define resource schemas, and generate fake data for testing and prototyping web and mobile applications. Users define resources in a web UI and mockAPI provisions a fully working REST endpoint with CRUD semantics, custom response codes, and seed data so teams can prototype against realistic API behavior without standing up a backend.

mockAPI publishes 1 API on the APIs.io network. Tagged areas include API Mocking, CRUD, Mock Server, Mocking, and Platform.

The mockAPI catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

mockAPI’s developer surface includes documentation, getting-started guide, GitHub presence, and 6 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/mockapi: open an issue to ask a question, or submit a pull request to add artifacts.
