JamFrame + REST API

What you can do

  • Five formats

    PNG, JPEG and WebP up to 3× scale, multi-page PDFs and MP4 video with sound.

  • Many sizes in one call

    Ask for up to 10 sizes and Smart Resize lays out each one.

  • Async jobs and webhooks

    Queue long renders, poll the job or get a signed webhook when it's done.

  • AI inside the request

    Send a prompt instead of text or an image, or translate the whole design into another language.

  • Signed and dynamic URLs

    Render from a plain link in an <img> tag or email, with caching and credit caps.

  • Post in the same call

    Render and publish to social accounts in one request.

Questions

JamFrame and REST API

How fast is a render?
Images usually come back in a second or two. Videos take longer, so long renders run as jobs you can wait for or get a webhook about.
What does a call cost?
One render credit per image or PDF page and one per second of video. Failed renders and cache hits are free.
  • Node.js SDK A typed client for Node.js and TypeScript.
  • Python SDK Sync and async clients for Python.
  • Webhooks Signed events when renders, posts and workflows finish.
  • MCP server Give any MCP-compatible agent a design tool with 17 actions.
