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
