## Which one, for what

### Higgsfield API (B)

Good for: An agent that wants several vendors' video models behind one key, one request lifecycle and safe retries, at published per-second prices.

Ahead on:
- Reliability, 85 against 35
- Schema & documentation, 69 against 48
- Agent ergonomics, 77 against 55
- Security & auth, 48 against 28
- Maintenance & community, 75 against 57
- Transparency & trust, 61 against 46

Watch for: API inputs and outputs can train Higgsfield's models by default. The opt-out is a workspace setting, processed within 10 business days

### Vidu API (E)

Good for: Batch jobs that can wait for off-peak prices and want reference-to-video or start-end frames with sound.

Also in its favour:
- Runs on your own machine

Watch for: No llms.txt, OpenAPI file or error-code reference

## Verdicts

**Higgsfield API.** One asynchronous API for 67 video and 17 image catalogue entries, with idempotency keys, per-second list prices public without a login, and failed or moderated jobs not charged. API inputs and outputs train Higgsfield's models unless the workspace opts out, and the docs carry no changelog. The API returns 400 at the concurrency limit, with no Retry-After.

**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

### Higgsfield API

1. Send `Authorization: Key <key_id>:<key_secret>` to https://api.higgsfield.ai. A Bearer token is rejected
2. Send a fresh `Idempotency-Key` with every generation. After a timeout or 5xx, repeat the same request with the same key, then read `status_url`
3. Treat a 400 whose `detail` mentions concurrent requests as a limit, not a bad request. Wait for a running job to finish before submitting more
4. Poll `status_url` from 2 seconds up to 10 with jitter, and stop on `completed`, `failed`, `nsfw` or `canceled`
5. Download output within seven days. Media files may be deleted after that
6. Read the model's own docs page for its schema. The OpenAPI file lists only a few models

### 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
