Hosted MCP remains beta.\n\n**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.\n\n## Before you call either\n\n### HyperFrames\n\n1. Use the local CLI when project access and repeatable rendering matter.\n2. Preview the composition and check assets before rendering.\n3. Confirm account eligibility and credit cost before using the hosted beta.\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. 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\n5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls\n\n## Questions\n\n### Which is better for AI agents, HyperFrames or Kling AI API?\n\nHyperFrames scores 39.1 (E) on agent readiness against Kling AI API's 21.7 (F), and leads in 4 of 7 scored categories.
