Akool Image Generation API

openapi: 3.0.3
info:
  title: Akool Open Authentication Image Generation API
  description: 'The Akool OpenAPI exposes Akool''s generative AI video and image tools over HTTPS REST under https://openapi.akool.com. Covered here are the Talking Avatar, Talking Photo, Face Swap, Video Translation, Image Generation, and Live Avatar (real-time streaming) products. Generation is asynchronous: callers create a task and either poll by id or receive an encrypted webhook callback when the task completes (video_status / image_status / job status 1=queueing, 2=processing, 3=completed, 4=failed). Requests authenticate with an `Authorization: Bearer {token}` header (token minted from clientId / clientSecret at POST /api/open/v3/getToken) or a direct `x-api-key` header. This document is authored by API Evangelist from Akool''s public documentation (docs.akool.com) and hand-models request/response shapes at a high level; consult the live docs and Akool''s own published OpenAPI files for exhaustive field detail.'
