Recipes

Short current-platform recipes for common Sume API workflows.

This page is a short index of recipes. For Avatar, the canonical /v1/avatar-1.0/* routes are the best choice. The deep guides are in Models.

A Format that you run for your own customers has a longer recipe of its own. Refer to Embed a Format in your product.

  • Avatar photo input: input.image_url
  • Avatar Video product reference: product_image
  • Avatar Video scene photo reference: scene.image_url
  • Face swap / captions source: video_url

Refer to Media inputs.
