## Which one, for what

### 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.

Watch for: Developer docs, API terms and pricing render only with JavaScript

### Replicate video models (B)

Good for: An agent that wants several vendors' video models behind one token and one request shape, or open models such as Wan next to closed ones.

Ahead on:
- Reliability, 75 against 15
- Schema & documentation, 86 against 15
- Agent ergonomics, 72 against 27
- Security & auth, 41 against 20
- Payments & pricing, 30 against 20
- Maintenance & community, 48 against 24
- Transparency & trust, 72 against 43

Also in its favour:
- Runs on your own machine

Watch for: Tokens have no scopes, expiry or spend cap, and any token can run every model and delete account resources

## Verdicts

**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.

**Replicate video models.** One bearer token reaches more than twenty official video models at published per-second prices, each with a typed input schema, and failed runs aren't charged. Tokens have no scopes or spend cap, no SLA is published, and the terms let Replicate withdraw any model without notice.

## Before you call either

### 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

### Replicate video models

1. Call official models at `POST /v1/models/{owner}/{name}/predictions` with no version, then poll `GET /v1/predictions/{id}` or pass `webhook`. Video jobs usually outlast the 60-second `Prefer: wait` window
2. Download the output file within the hour. API predictions lose inputs, outputs and logs after 60 minutes
3. Read the model's price tiers before setting `resolution`, `mode` or `generate_audio`. Kling 3.0 runs from $0.168 to $0.42 a second and Veo 3.1 doubles with audio
4. Send `Cancel-After` on every create. There is no idempotency key, so a blind retry is a second paid video
5. Keep credit above $20 or enable auto-reload. Low balances are throttled, and granted credit with no card is held to 6 requests a minute
