The FilePreviews.io service is composed of a very simple API organized around REST.
There's an endpoint that can be used to request a preview, which happens asynchronously. The returned results are useful for different scenarios, allowing you to poll until requested previews and metadata are available, or use webhooks.
We support cross-origin resource sharing to allow you to interact securely with your API from a client-side web application. JSON will be returned in all responses from the API, including errors.
Libraries are available in several languages.
Currently, the FilePreviews API is versioned with a URL segment, such as /v2/. The current production version of the API is Version s, so your calls should use /v2/ as the version segment.
