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.\n\n**Runway API.** OpenAPI 3.1, llms.txt and Markdown copies of every docs page. Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog.\n\n## Before you call either\n\n### Higgsfield API\n\n1. Send `Authorization: Key \u003ckey_id\u003e:\u003ckey_secret\u003e` to https://api.higgsfield.ai. A Bearer token is rejected\n2. 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`\n3. 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\n4. Poll `status_url` from 2 seconds up to 10 with jitter, and stop on `completed`, `failed`, `nsfw` or `canceled`\n5. Download output within seven days. Media files may be deleted after that\n6. Read the model's own docs page for its schema. The OpenAPI file lists only a few models\n\n### Runway API\n\n1. Send `X-Runway-Version: 2024-11-06` on every request or it fails\n2. Use the SDK's wait-for-output helper or poll GET /v1/tasks/{id} until SUCCEEDED or FAILED\n3. Don't retry a SAFETY.* failure unchanged. It's moderation, not an outage\n4. Take model IDs from the models page, not memory. Two were removed without notice on 2026-07-30\n5. Copy outputs to your own storage. URLs expire within 24 to 48 hours\n\n## Questions\n\n### Which is better for AI agents, Higgsfield API or Runway API?\n\nHiggsfield API scores 63.5 (B) on agent readiness against Runway API's 60.8 (C), and leads in 4 of 7 scored categories. Runway API leads on schema \u0026 documentation.\n\n### Do Higgsfield API and Runway API need an API key?\n\nBoth need an API key.\n\n### Can an agent call Higgsfield API and Runway API without installing anything?\n\nYes.
