Developer docs, API terms and pricing render only with JavaScript.\n\n**OpenAI Sora API.** Six months' notice, from 24 March to 24 September 2026. Shut down on 2026-09-24, so every call fails.\n\n## Before you call either\n\n### Kling AI API\n\n1. Sign a JWT (HS256) with `iss` set to your AccessKey and a 30 minute `exp`, then send it as a bearer token\n2. Generate a new key pair if you need Kling 3.0 Turbo. Older keys don't reach it\n3. Create with POST /v1/videos/text2video or /v1/videos/image2video, then poll the task id until it succeeds\n4. Take model IDs and prices from kling.ai/llms.txt. The HTML docs need JavaScript\n5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls\n\n### OpenAI Sora API\n\n1. Don't call /v1/videos. The Videos API was removed on 2026-09-24\n2. Remove `sora-2`, `sora-2-pro` and the dated snapshots from configs and fallback chains\n3. Pick another provider from this category. OpenAI has no video model on its API now\n\n## Other comparisons with Kling AI API or OpenAI Sora API\n\n- [Alibaba Wan (Model Studio) vs Kling AI API](https://www.anchorterminal.com/compare/alibaba-wan-vs-kling.md)\n- [Alibaba Wan (Model Studio) vs OpenAI Sora API](https://www.anchorterminal.com/compare/alibaba-wan-vs-openai-sora.md)\n- [Google Veo vs Kling AI API](https://www.anchorterminal.com/compare/google-veo-vs-kling.md)\n- [Google Veo vs OpenAI Sora API](https://www.anchorterminal.com/compare/google-veo-vs-openai-sora.md)\n- [Kling AI API vs Luma AI API](https://www.anchorterminal.com/compare/kling-vs-luma.md)\n- [Kling AI API vs MiniMax Video API](https://www.anchorterminal.com/compare/kling-vs-minimax-video.md)\n- [Kling AI API vs Pika API](https://www.anchorterminal.com/compare/kling-vs-pika.md)\n- [Kling AI API vs PixVerse API](https://www.anchorterminal.com/compare/kling-vs-pixverse.md)\n- [Kling AI API vs Runway API](https://www.anchorterminal.com/compare/kling-vs-runway.md)\n- [Kling AI API vs Vidu API](https://www.anchorterminal.com/compare/kling-vs-vidu.md)\n- [Luma AI API vs OpenAI Sora API](https://www.anchorterminal.com/compare/luma-vs-openai-sora.md)\n- [MiniMax Video API vs OpenAI Sora API](https://www.anchorterminal.com/compare/minimax-video-vs-openai-sora.md)\n- [OpenAI Sora API vs Pika API](https://www.anchorterminal.com/compare/openai-sora-vs-pika.md)\n- [OpenAI Sora API vs PixVerse API](https://www.anchorterminal.com/compare/openai-sora-vs-pixverse.md)\n- [OpenAI Sora API vs Runway API](https://www.anchorterminal.com/compare/openai-sora-vs-runway.md)\n- [OpenAI Sora API vs Vidu API](https://www.anchorterminal.com/compare/openai-sora-vs-vidu.md)\n",
