Files.fm API

Build and automate secure file upload, storage, sharing, processing, and content management workflows using the Files.fm API and MCP.

The Files.fm API allows developers to integrate scalable ES-based cloud storage into web, mobile, desktop, and server-side applications without building and maintaining their own file storage infrastructure and heavy file processing such as video, audio, or image conversion and streaming.
