API key
Your agent will need an Extract.FAST API key. Create 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"API keys can be created from the account dashboard, but extraction jobs require Pro access and account credits. Add credits or subscribe before asking an agent to run API job work; the starter credit pack is $5 for 2,500 credits.
Public API only
Use the public single-job endpoints: POST /estimate/{sourceFileExtension}, POST /extract, POST /transcribe, GET /job/{id}, and GET /job/{id}/download.
