Mask API is a powerful and flexible tool designed to help programmers and companies customize the response format of endpoint APIs, enabling selective field filtering and data transformation in API responses.
Mask API publishes 1 API on the APIs.io network. Tagged areas include API Tools, Developer Tools, and Response Filtering.
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/mask-api: open an issue to ask a question, or submit a pull request to add artifacts.
