As a reminder, the API documented in this article has been deprecated and is being retired in stages. The “Get user-facing version for a file” request, do=checkForUpdates, has already stopped working for new files uploaded after 8 May 2026. We currently intend to turn off all remaining endpoints on 1 June 2026 and are moving to our new authenticated API. For checking updates to your own files, we recommend using our new Version Check Keys. These include API documentation in your Account Settings. Please note that Version Check Keys are limited to checking updates for files you own. For other use cases, our new Public API keys are available on request for non-commercial use. These allow you to retrieve file details in bulk, up to 10,000 files at a time, sorted by file update date by default. These new endpoints include far more details about files, including tags, screenshots and more. We plan to share more in the coming months about the full deprecation of the “Get user-facing version for a file” endpoint. If you have any questions, please let us know.
