Assessment: 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.

## Facts

- Kind: Model platform · vendor: fal (Features & Labels, Inc.) · category: Video generation · legal entity: Features & Labels, Inc. · provenance 66/100
- Endpoint: `https://queue.fal.run` (HTTP, Streamable HTTP)
- Auth: OAuth or key · pricing: Pay per use · x402: no · licence: unknown
- Probe metrics: not measured yet (probes haven't run)
- Models: Seedance 2.5 and 2.0, Kling v3, o3 and 2.6, Veo 3.1 (standard, Fast, Lite), MiniMax H3 and H3 Max, Wan 3.0 and 2.7, Gemini Omni Flash, Grok Imagine Video 1.5, Flux 3 video, LTX 2.5 and 2.3, PixVerse v6, Vidu Q3, Happy Horse 1.1, Luma Ray 3.2, Hunyuan Video, Kandinsky 6 (https://api.fal.ai/v1/models?category=text-to-video&limit=100)
- Max clip length: Per model. Seedance 2.5 4 to 30 seconds, Wan 3.0 2 to 30, Kling v3 3 to 15, Veo 3.1 4, 6 or 8
- Resolution: Per model. Veo 3.1 720p, 1080p and 4K. LTX 2.5 Fast 720p to 4K. Seedance 2.5 and Wan 3.0 480p to 1080p
- Audio: Native audio on Veo 3.1, Kling v3, Seedance 2.5 and LTX 2.5. `generate_audio` defaults to true and raises the price on Veo 3.1 and Kling v3
- Typical job time: Async queue. No job times published. The MCP `run_model` tool waits 45 seconds by default, then returns a request ID
- Licence of output: Set by each model. The catalogue marks `license_type` (commercial on most, research on `fal-ai/ltx-video`). The terms warrant nothing about rights in output
- Free tier: None published. Promotional credits and grants exist and expire on their own terms
- Rate limits: Concurrency 2 for a new account, rising automatically to 40 self-serve with paid invoices. Queued requests don't count and aren't rejected
- Data retention: Request payloads 30 days by default, off with `X-Fal-Store-IO: 0`. Media lifetime set with `X-Fal-Object-Lifecycle-Preference`
- MCP server: `https://mcp.fal.ai/mcp-relay`, Streamable HTTP with OAuth, 11 tools, no extra charge
- Deprecated endpoints: 22 of 159 text-to-video endpoints, among them Sora 2, Veo 3, Veo 2 and Kling 1.x to 2.1, with no removal dates
- Prices: Kling v3 Pro with audio $0.168 per second of video; Kling v3 Standard with audio $0.126 per second of video; Veo 3.1 with audio, 720p or 1080p $0.40 per second of video; Veo 3.1 Fast with audio, 720p or 1080p $0.15 per second of video; Seedance 2.5 720p $0.473 per second of video; Wan 3.0 720p $0.10 per second of video; MiniMax H3 Max 768p $0.08 per second of video; LTX 2.5 Fast 720p $0.09 per second of video; Grok Imagine Video 1.5 720p $0.14 per second of video

## Before you call it

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`

## Connect

pip install fal-client   # or: npm install --save @fal-ai/client
```

curl -X POST https://queue.fal.run/fal-ai/kling-video/v3/pro/text-to-video -H "Authorization: Key $FAL_KEY" \
  -H "Content-Type: application/json" -d '{"prompt":"ocean waves at sunset, slow dolly in","duration":"5","generate_audio":false}'
```

```bash
claude mcp add --transport http --scope user fal https://mcp.fal.ai/mcp-relay
