Kling AI API F

Good for Buyers who want Kling's quality and price and are willing to sign JWTs and read the docs in a browser.

Verdicts

fal video models

One key and one queue API reach 137 active text-to-video endpoints, each with a published price, an OpenAPI document and an llms.txt. Billing units, duration formats and audio pricing differ per model, there is no free tier, and a person must sign up in a browser and buy credit.

Kling AI API

Kling 3.0 from $0.084 a second, with audio from $0.126. Developer docs, API terms and pricing render only with JavaScript.

Before you call either

fal video models

  1. Submit to queue.fal.run, keep the request_id, then poll status_url or set fal_webhook. Never resubmit to check progress, because each submit is a new billable job
  2. Read https://fal.ai/models/<endpoint-id>/llms.txt before a call. duration is the string "5" on Kling, "8s" on Veo 3.1 and an integer on Wan 3.0
  3. Set generate_audio on purpose. It defaults to true and raises the Kling v3 Pro price from $0.112 to $0.168 a second and Veo 3.1 from $0.20 to $0.40
  4. Check metadata.status in https://api.fal.ai/v1/models before pinning an endpoint. Deprecated endpoints carry no removal date
  5. Use an API-scope key, never an ADMIN key. A new account runs 2 requests at once, so long video jobs queue behind each other
  6. The MCP relay has no server-side approval gate. Call get_pricing and get the owner's approval before submit_job

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
