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.

Vidu API

Q3 Turbo from $0.035 a second at 540p, about half that off-peak. No llms.txt, OpenAPI file or error-code reference.

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

Vidu API

  1. Send Authorization: Token $VIDU_API_KEY. The scheme is Token, not Bearer
  2. POST the task, then poll the Get Creation endpoint by task id or set callback_url
  3. Set off_peak only for jobs that can wait up to 48 hours. It roughly halves the credit rate
  4. Set audio to true for dialogue and sound on Q3. It's off by default
  5. Keep the AI-generated label on outputs. The terms forbid removing it
