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.

OpenAI Sora API

Six months' notice, from 24 March to 24 September 2026. Shut down on 2026-09-24, so every call fails.

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

OpenAI Sora API

  1. Don't call /v1/videos. The Videos API was removed on 2026-09-24
  2. Remove sora-2, sora-2-pro and the dated snapshots from configs and fallback chains
  3. Pick another provider from this category. OpenAI has no video model on its API now
