Promptchan AI API Documentation

The Promptchan API lets you generate AI images and videos, and drive AI chat, directly from your own application. Requests are authenticated with an API key sent in an x-api-key header. The full, interactive endpoint reference is below.

What the API covers

• Image generation — POST /api/external/create generates an image from a text prompt with control over style, pose and quality.
• Chat — POST /api/external/chat drives a conversation with an AI character.
• Video generation — POST /api/external/video_v4/submit queues a video, then poll status_with_logs and fetch result when it completes.
