## Before you call it

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

## Connect

```bash
curl -X POST https://api-singapore.klingai.com/v1/videos/text2video \
  -H "Authorization: Bearer $KLING_JWT" -H "Content-Type: application/json" \
  -d '{"model_name":"kling-v3","prompt":"a red fox running through snow","mode":"std","duration":"5"}'
```
