Bytescale

Bytescale (formerly Upload.io) is a file upload, storage, image / video / audio processing, and CDN platform for developers. A simple REST API uploads files (binary, multipart form data, or from a URL), manages files and folders, and serves optimized media through real-time, URL-based transformations on a global CDN.

Bytescale publishes 3 APIs on the APIs.io network: Files API, Folders API, and Upload API. Tagged areas include File Upload, Storage, Image Processing, CDN, and Media.

Bytescale’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/bytescale: open an issue to ask a question, or submit a pull request to add artifacts.
