## Which one, for what

### fal video models (BB)

Good for: An agent or team that wants to compare or switch between Seedance, Kling, Veo, MiniMax, Wan and open-weights video models with one key and one queue contract.

Ahead on:
- Reliability, 77 against 43
- Schema & documentation, 89 against 81
- Agent ergonomics, 81 against 55
- Security & auth, 73 against 38
- Maintenance & community, 81 against 75
- Transparency & trust, 64 against 44

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: Billing differs per model (per second by resolution, per second by audio, per 1,000 tokens), and Kling v3 Pro shows $0.14 on the pricing page against $0.112 or $0.168 on its model page

### sync. labs MCP server (D)

Good for: Agents that lip-sync or dub video into other languages.

Ahead on:
- Payments & pricing, 30 against 20

Also in its favour:
- Open source

Watch for: No read-only mode


## Why the edge

### Security & auth: fal video models +35

- fal video models (73): Keys take one of seven permission presets (API, SERVERLESS, DEPLOY, COMPUTE, BILLING, READONLY, FULL) or a custom permission list, can be limited to named models and can expire after 1 hour to 1 year, since 9 October 2026. Legacy ADMIN and API keys still work. The MCP relay uses OAuth with browser sign-in, and its scopes aren't documented (30). A READONLY preset grants no write access, and model limits narrow a key further. The MCP docs state that the server has no server-side approval gate before a paid generation (15). Returns generated media and fal's own catalogue text (10). Request payloads are kept 30 days in the dashboard history, and usage and analytics APIs report per-request spend (10). `https://fal.ai/.well-known/security.txt` returned 404 on 1 November 2026 and no disclosure policy or bug bounty was found. The enterprise page claims SOC 2 certification, the DPA of 31 July 2026 has a data security exhibit, and the trust centre at trust.fal.ai renders only in a browser, so the report and its scope were unread, per the 8 October check (8).
- sync. labs MCP server (38): OAuth per organisation, or an API key in the environment (22 of 30). No read-only mode (3 of 20). Media in and out, no third-party text (10). No audit log found (0). No security programme found (3 of 20). 22 + 3 + 10 + 0 + 3 = 38.

### Reliability: fal video models +34

- fal video models (77): Graded as a hosted service on the queue API. Instatus page at status.fal.ai with components for Model API, Serverless API, Official Models and the dashboards, and monthly uptime figures (20). The notice history, re-read on 1 November 2026, has two notices in the 90 days from 3 August, a 30-minute major outage of synchronous calls to `fal.run` on 4 September (the queue wasn't named, so partial) and 18 minutes of degraded performance on 29 September, and none in October (20). Concurrency is published, 2 for a new account rising to 40 self-serve with paid invoices over four weeks, and queued requests are never rejected (15). A 429 carries type `concurrent_requests_limit` and `X-Fal-needs-retry: 1`, the docs give backoff of 1, 2, 4 and 8 seconds, the queue retries 503, 504 and connection errors up to 10 times, and backup domains are documented. There is no idempotency key, and one page says concurrency requeues have no maximum while another says 10 (12). The enterprise page mentions SLA guarantees but no SLA document is published (0). The queue API is generally available (10).
- sync. labs MCP server (43): Status page at status.sync.so with maintenance and previous incidents (20). History not read (5). No MCP limits found (0). The source has abort-signal handling and recovery guidance for long jobs (8 of 15). No SLA found (0). Version 0.2.4, not labelled beta (10). 20 + 5 + 0 + 8 + 0 + 10 = 43.

### Agent ergonomics: fal video models +26

- fal video models (81): Graded on the queue API, with the hosted MCP server noted. Results are small JSON with a file URL, and a model's llms.txt is 6 to 8 KB loaded on demand. The MCP server has 11 tools with schema and pricing lookups (20). The catalogue API takes `category`, `limit` and a cursor, queue status reports position, webhooks replace polling, and most models take duration and resolution, though names and types differ (18). Errors carry a machine-readable `error_type`, the same value in `X-Fal-Error-Type`, and guidance on which to retry (18). No idempotency key. Server-side retries, `X-Fal-No-Retry`, a cancel endpoint and no charge for 5xx failures reduce the cost of a failed call, but a repeated submit is a second billable job, and the MCP docs don't mention readOnlyHint or destructiveHint (10). Few required parameters, and official Python and JavaScript clients plus Swift, Kotlin and Dart (15).
- sync. labs MCP server (55): A generated catalogue filtered by client profile, curated for ChatGPT (15). Project history and estimates (12 of 20). Recovery tools; errors not documented (8 of 20). Annotations not read (5 of 20). OAuth or a key, npm package and library use (15). 15 + 12 + 8 + 5 + 15 = 55.

### Transparency & trust: fal video models +20

- fal video models (64): Closed platform with published terms (8 September 2026) and API Services supplemental terms. The clients are MIT and the catalogue marks each model's `license_type`. The terms warrant nothing about rights in output, and a clause bars scripts that integrate with the services without written authorisation, which sits oddly with an API product (13). Data handling is documented and mostly agrees. Request payloads are kept 30 days with an opt-out header and a delete API, the API Services terms say client content isn't used to train or develop fal's products except on models marked Pending Enterprise Ready, and the privacy policy of 22 July 2026 deletes account data 30 days after closure. The terms still let fal use usage data to develop AI models, and content sent to a third-party model goes to that third party (22). Model pages now carry dated deprecation notices, Veo 3.1 and its sub-endpoints on 17 November 2026, Luma Ray 2 on 25 October with a named replacement, and the key docs say presets can be refined. But 31 of 152 text-to-video endpoints are marked deprecated in the catalogue, most without a date, and there is no written policy or changelog entry (12). The DPA names a subprocessor list at trust.fal.ai/subprocessors with 15 days' notice of changes, but that page renders only in a browser, and the privacy policy says processing is in the United States and other countries (10).
- sync. labs MCP server (44): MIT open source (30). Data handling not read (5 of 30). No deprecation policy; earlier tool names documented as superseded (5 of 20). Subprocessors not found (0). 30 + 5 + 5 + 0 = 40.

### Payments & pricing: sync. labs MCP server +10

- fal video models (20): No x402, MPP or L402 in the docs, pricing page or terms (0). Per-model prices are public without a login on fal.ai/pricing and on every model page and llms.txt, and a pricing API returns unit prices by endpoint ID (20). No standing free tier. The terms and FAQ mention promotional credits and grants with their own expiry, and the terms require credit bought in advance (0). A person signs up in a browser and buys credit, and the MCP relay needs browser sign-in (0).
- sync. labs MCP server (30): No machine payment protocol (0). Per-second prices published (20). A free try for short videos (10 of 20). A person signs up (0). 0 + 20 + 10 + 0 = 30.

### Schema & documentation: fal video models +8

- fal video models (89): An OpenAPI 3.1 document for the queue API and one for the platform APIs, and a per-endpoint OpenAPI 3.1 document from the catalogue API with `expand=openapi-3.0`, read for `fal-ai/kling-video/v3/pro/text-to-video` on 1 November 2026 (25). The 8 October reading of per-endpoint documents on fal.ai's `?endpoint_id=` path is struck, because fal.ai's robots.txt disallows that query. A docs llms.txt, Markdown twins of docs pages and an llms.txt per model with schema, defaults and price (10). Model pages state what each model does but rarely when not to use it, and the Seedance 2.5 catalogue text says up to 720p while its schema lists 1080p (12). Inputs are typed with enums, ranges and defaults, but `duration` is a string enum on Kling, a string with a unit on Veo 3.1 and an integer on Wan 3.0, and Kling's rule that one of `prompt` or `multi_prompt` is needed sits in prose with a required example of `{}` (13). Examples in cURL, Python and JavaScript on every model, a model error reference with typed errors such as `content_policy_violation` and `video_duration_too_long`, and a request error reference with 13 types (14). Versioned endpoint IDs and a dated public changelog (15).
- sync. labs MCP server (81): Tools generated from the public API specification plus workflow tools, with typed schemas in the source (25). llms.txt and .md pages (10). Tool table with descriptions (14 of 20). Typed from the API spec (12 of 15). Examples and an estimates tool; errors not documented (8 of 15). Tags v0.2.2 to v0.2.4 and dated commits (12 of 15). 25 + 10 + 14 + 12 + 8 + 12 = 81.

## Verdicts

**fal video models.** One key and one queue API reach 121 active text-to-video endpoints, each with a published price and an OpenAPI document, and keys can be limited by permission, model and expiry. 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.

**sync. labs MCP server.** sync. labs' MCP server is open source, generated from its API spec with workflow tools on top, and released often, with clear per-second prices for lip sync and dubbing. Security and data handling are thinly documented, and there's no read-only mode.

## 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` and the model page's notice before pinning an endpoint. Veo 3.1 is deprecated on 17 November 2026
5. Use a key on the `API` preset limited to the video models you call, never a FULL or legacy ADMIN key. A new account runs 2 requests at once
6. The MCP relay has no server-side approval gate. Call `get_pricing` and get the owner's approval before `submit_job`

### sync. labs MCP server

1. Get an estimate before long generations
2. Dub or lip-sync only voices and faces the user has the right to use
3. Check the active organisation before connecting with OAuth
