AgentGen — HTML → PDF & Image

Convert any HTML to a PDF or screenshot image via the AgentGen API.

Free tier — no sign-up required

The /v1/generate/image and /v1/generate/pdf endpoints work without an API key. Just omit the X-API-Key header.

Limits:

  • 1 request per 60 seconds per IP (returns 429 if exceeded)
  • Single-page PDFs only
  • A small agent-gen.com watermark is added to all output

    • # Free tier — generate an image (no API key)
agentgen image --html "
    Hello
    " --output hello.png
    Free tier — generate a PDF (no API key)
    
agentgen pdf --html "
    Invoice
    " --output invoice.pdf

    Simply omit AGENTGEN_API_KEY and the CLI uses the free tier automatically.

    Authenticated tier — no watermark, no rate limit

    Set your API key to use the full API. New accounts at agent-gen.com include free tokens — no credit card required to get started.

    export AGENTGEN_API_KEY=your_key_here

    Check your balance:

    If you run out, the CLI prints your current balance, the amount required, and a direct link to buy more tokens.
