## 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 50
- Schema & documentation, 69 against 43
- Agent ergonomics, 77 against 66
- Maintenance & community, 75 against 57
- Transparency & trust, 61 against 53

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

### Luma AI API (D)

Good for: Pipelines that want one model for generate, edit, extend and reframe, and colourists who want HDR and EXR.

Watch for: Video rates are marked as subject to change before general availability

## 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.

**Luma AI API.** Dollar prices per clip, $0.30 for 5 seconds at 720p, no credits to convert. Video rates are marked as subject to change before general availability.

## 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

### Luma AI API

1. Send model `ray-3.2` and type `video`, with resolution and duration inside `video`. Older model names are rejected
2. Poll GET /v1/generations/{id} until completed or failed, then copy the presigned URL
3. On 429, read `detail`. Rate limit exceeded means wait Retry-After, Too many concurrent jobs means wait for a job to finish
4. Use keyframes with `keyframe_indexes` for 10 second clips. start_frame and end_frame only work at 5 seconds
