Developer docs, API terms and pricing render only with JavaScript. **OpenAI Sora API.** Six months' notice, from 24 March to 24 September 2026. Shut down on 2026-09-24, so every call fails. ## 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 ### OpenAI Sora API 1. Don't call /v1/videos. The Videos API was removed on 2026-09-24 2. Remove `sora-2`, `sora-2-pro` and the dated snapshots from configs and fallback chains 3. Pick another provider from this category.
