## Verdicts

**Kling AI API.** Kling 3.0 from $0.084 a second, with audio from $0.126. Developer docs, API terms and pricing render only with JavaScript.

**MiniMax Video API.** 2K with stereo audio at $0.13 a second, 768P at $0.08. No statement found on whether API inputs train models, and the privacy policy needs a browser.

## Before you call either

### Kling AI API

1. Sign a JWT (HS256) with `iss` set to your AccessKey and a 30 minute `exp`, then send it as a bearer token
2. Generate a new key pair if you need Kling 3.0 Turbo. Older keys don't reach it
3. Create with POST /v1/videos/text2video or /v1/videos/image2video, then poll the task id until it succeeds
4. Take model IDs and prices from kling.ai/llms.txt. The HTML docs need JavaScript
5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls

### MiniMax Video API

1. Use POST /v2/video_generation for H3 and poll GET /v2/query/video_generation/{task_id}. Tasks stay queryable for 7 days
2. Set `ratio` for text-to-video. `adaptive` isn't allowed there
3. Pass `callback_url` to skip polling. Your endpoint must echo the `challenge` within 3 seconds
4. A 402 means the balance is empty and a 422 means moderation blocked the content. Don't retry either unchanged
