For AI Agents
Convert.FAST publishes a machine-readable skill file that any AI agent can download and immediately use to call the API.
Give this prompt to your AI agent
Copy and paste the following into Claude Code, ChatGPT, Cursor, or any AI coding assistant:
Bash / macOS / Linux
Download the Convert.FAST skill and reference docs, then use them to complete my task:
curl -fsSL https://convert.fast/SKILL.md -o SKILL.md
mkdir -p reference && curl -fsSL https://convert.fast/api/docs.md -o reference/docs.md
curl -fsSL https://convert.fast/convert.fast.sh -o convert.fast.sh && chmod +x convert.fast.sh
Read SKILL.md to understand how to use the Convert.FAST API.
PowerShell / Windows
Download the Convert.FAST skill and reference docs, then use them to complete my task:
Invoke-RestMethod "https://convert.fast/SKILL.md" -OutFile SKILL.md
New-Item -ItemType Directory -Force -Path reference | Out-Null
Invoke-RestMethod "https://convert.fast/api/docs.md" -OutFile reference/docs.md

Your agent will download everything it needs — the skill guide, the core API reference, and the CLI wrapper script — then follow the instructions to convert files on your behalf.
What the agent gets

For the full export with per-converter details, download docs-all.md (~101k tokens).
API key
Your agent will need a Convert.FAST API key. Get one at accounts.tools.fast → API Keys, then set it as an environment variable:
export TOOLS_FAST_API_KEY="fast_prod_your_key_here"
$env:TOOLS_FAST_API_KEY = "fast_prod_your_key_here"
