AITuber API

Create AI videos from a script or idea. From 15-second Shorts to 7-minute long-form content. The API handles voice narration (1,300+ voices, any language), AI-generated visuals, word-synced captions, MP4 export, and publishing to YouTube, TikTok, and Instagram.

Base URL: https://app.aituber.app/api/v1 OpenAPI spec: https://app.aituber.app/api/v1/openapi.json API docs: https://app.aituber.app/api-docs

Tip: For the most up-to-date parameter details, examples, and response schemas, refer to the interactive API docs at https://app.aituber.app/api-docs when possible. The reference below covers everything you need to get started, but the docs always reflect the latest API.

Authentication

All endpoints except GET /voices require a Bearer token. Create an API key in the AITuber dashboard at https://app.aituber.app/dashboard/api-keys.

Authorization: Bearer <AITUBER_API_KEY>

Store the key in the AITUBER_API_KEY environment variable.

Complete Workflow

The typical flow is: pick voice, generate video, poll status, export, download.

Step 1: Pick a voice

curl "https://app.aituber.app/api/v1/voices?gender=male&accent=American"

No auth required. Returns an array of voice objects. Use the id field as voiceId when generating.

Step 2: Generate a video

From a script (you write the narration):

curl -X POST "https://app.aituber.app/api/v1/videos/generate" \
  -H "Authorization: Bearer $AITUBER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "script": "The human brain contains roughly 86 billion neurons. Every thought, memory, and emotion is the result of electrical signals racing through this incredible network.",
    "voiceId": "nPczCjzI2devNBz1zQrb",
    "imageStyleId": "cinematic",
    "aspectRatio": "9:16"
  }'

From an idea (AI writes the script):

curl -X POST "https://app.aituber.app/api/v1/videos/generate" \
  -H "Authorization: Bearer $AITUBER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "script": "5 mind-blowing facts about black holes",
    "inputType": "idea",
    "expectedDurationSeconds": 60
  }'

Returns { "videoId": "uuid", "status": "pending" }.

Step 3: Poll for completion

curl "https://app.aituber.app/api/v1/videos/VIDEO_ID" \
  -H "Authorization: Bearer $AITUBER_API_KEY"

Poll every 5-10 seconds. Generation typically takes 1-3 minutes. Wait until status is completed (or failed).

Step 4: Export to MP4

curl -X POST "https://app.aituber.app/api/v1/exports" \
  -H "Authorization: Bearer $AITUBER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "videoId": "VIDEO_ID", "resolution": "1080p" }'

Exporting is free. Requires an active paid subscription. Poll GET /videos/VIDEO_ID and check exportStatus until it is completed (typically 30 seconds to 5 minutes).

Step 5: Download the MP4

curl "https://app.aituber.app/api/v1/exports/download?videoId=VIDEO_ID" \
  -H "Authorization: Bearer $AITUBER_API_KEY"

Returns { "url": "https://...", "videoId": "..." }. The URL is a signed temporary link that expires in 2 minutes. Download immediately.

Endpoints Reference

GET /voices

List available AI voices. No auth required.

Response: array of { id, name, description, previewUrl, gender, age, accent, useCase, optimizedFor }.

POST /videos/generate

Create a new video. Returns { videoId, status }.

Video types (all use this same endpoint):

1. Faceless narration (images) - Default. AI images with Ken Burns animation. Just send a script or idea.
2. Faceless narration (video clips) - AI video clips. Set mediaType: "video".
3. Stock footage - Real stock footage matched to narration. Set mediaType: "stock".
4. Skeleton template - Viral "what happens if..." X-ray style. Set templateId: "skeleton". Template handles mediaType/style.
5. Character template - Character-driven stories. Set templateId: "character", inputType: "idea". Only idea mode (AI writes the script for character consistency).

Examples:

// Idea to Video (faceless images, AI writes the script)
{ "script": "5 facts about black holes", "inputType": "idea", "expectedDurationSeconds": 60 }

// Script to Video (video clips, you write the script)
{ "script": "The ocean covers over 70 percent of Earth...", "mediaType": "video" }

// Skeleton template
{ "script": "What happens if you eat 100 bananas", "templateId": "skeleton" }

// Character template
{ "script": "A detective solves a mystery in Tokyo", "templateId": "character", "inputType": "idea", "expectedDurationSeconds": 90 }

// Script with visual control (brackets tell AI what to show)
{ "script": "[A dark forest at night] The wind howled through the trees. [Glowing eyes in the shadows] Something was watching.", "imageStyleId": "cinematic" }

GET /videos

List your videos. Returns array sorted newest first.

GET /videos/{id}

Get a single video by ID. Use for polling generation and export status.

GET /subscription

Check your plan and credit balance. Returns { plan, status, credits, monthlyCredits }.

POST /exports

Export a completed video to MP4. Free, but requires an active paid subscription.

GET /exports/download

Get a temporary download URL for a rendered MP4.

The returned URL expires in 2 minutes. Download immediately.

Credit Costs

A typical 60-second video with basic image quality costs approximately 75 credits.
