Single-Request Image Generation endpoint

Copy page

We’ve released a powerful new endpoint that allows you to generate images from HTML/CSS in a single request using signed URLs. This new create-and-render endpoint eliminates the need for the traditional two-step process of creating an image and then fetching it.

Key benefits include:

  • Client-side friendly: Generate image URLs without exposing your API key
  • No POST requests: Skip the image creation step and go straight to rendering
  • HMAC authentication: Secure signed URLs prevent unauthorized usage
  • Direct image response: URLs return images immediately when accessed

This endpoint is perfect for scenarios where you need to generate image URLs from client-side code or want to simplify your image generation workflow. The endpoint uses HMAC SHA256 authentication to ensure security while keeping your API key private.
