## Verdicts

**Kling AI API.** Kling 3.0 from $0.084 a second, with audio from $0.126, and failed generations deduct no units. Developer docs and API terms render only with JavaScript, and Kling 4.0 isn't on the API as of 17 October 2026.

**Popcraft MCP.** OAuth connector without copying API keys. Published tool inventories disagree.

## 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. Don't plan on Kling 4.0 or clips over 10 seconds through this API yet. Kling 4.0 isn't on the developer platform as of 17 October 2026
5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls

### Popcraft MCP

1. Preview credit cost and obtain approval before submitting paid generation.
2. Discover the current tool list instead of assuming the advertised count.
3. Poll the existing job rather than resubmitting a generation after a timeout.
