Kling AI uses JWT (JSON Web Token) authentication. You generate a token from your Access Key (AK) and Secret Key (SK), then pass it as a Bearer token in every request. Tokens expire after 30 minutes.
Diagnoses and fixes Kling AI API errors like HTTP 400-503, task failures, and JWT issues with solutions for video generation troubleshooting.
Generates videos from text prompts or images, animates still images, and creates talking avatars from photos with audio using Kling AI models (VIDEO 3.0, Avatar 2.0, etc.). Handles multi-shot storyboards, character consistency, and prompt engineering.
API authentication patterns, SDK installation scripts, environment variable management, and connection testing for ElevenLabs. Use when setting up ElevenLabs authentication, installing ElevenLabs SDK, configuring API keys, testing ElevenLabs connection, or when user mentions ElevenLabs authentication, xi-api-key, ELEVENLABS_API_KEY, or ElevenLabs setup.

| Error | Cause | Fix |
|---|---|---|
401 Unauthorized | Invalid/expired JWT | Regenerate token, check AK/SK |
403 Forbidden | API access not enabled | Enable API in developer console |
| JWT decode error | Wrong secret key | Verify SK matches the AK pair |
| Token expired | >30 min since generation | Implement auto-refresh (see above) |
| Clock skew error | Server time mismatch | Use nbf: now - 5 for tolerance |
