API overview
jmgBB exposes a JSON-oriented HTTP API for uploads and image metadata. The web app calls this API; you can integrate the same endpoints from your own clients when permitted by our Terms of Service.
Base URL (for this deployment): https://api.jmgbb.com
POST /api/upload— multipart form fieldimage, optionaltitle, optionalAuthorization: Bearer …when signed in.GET /api/images/:id— public metadata for a hosted image (by short id or slug where supported).- Account-specific routes (albums, library, settings) require authentication; see signed-in flows in the web app.
