# FireImg Documentation

Welcome to the FireImg docs. Here you’ll find guides and references for uploading images, image URLs, and client libraries so you can integrate image optimization and delivery into your apps.

# Quick links

• CLI — Upload, delete, and list images from the terminal, CI, or a coding agent.
• API reference — HTTP API keys, presigned uploads, list, moderation, and delete.
• Image URL reference — Query-parameter image URLs, supported parameter aliases, and examples for FireImg image URLs in <img /> tags.
• Packages — @fireimg/js, @fireimg/react, the fireimg Ruby gem, and the fireimg Go module.
• For AI agents — How coding agents should upload with the CLI.

# Getting started

1. Sign up at FireImg and create a project.
2. Upload images that you want optimized:
   • In the FireImg app, open your project and choose Upload,
   • Install the FireImg CLI and run fireimg upload ./hero.jpg with an API key, or
   • Use the fireimg Ruby gem from a Rails (or other Ruby) app, or
   • Use the fireimg Go module from a Go app.
3. Point your image URLs through FireImg to get automatic optimization and CDN delivery.

• Example: <img src="https://img.fireimg.com/demo/images/img.jpg?width=800&quality=high" />
