This Higgsfield blog guide is for teams whose product ran on the Sora 2 API, which OpenAI shut down on 24 September 2026 without naming a replacement. Its main point is that the Higgsfield API keeps Sora's pattern of a background job, a status check or webhook and a file to download, so only the integration layer changes, and one key reaches more than 50 video and image models. It matches old workloads to Seedance 2.5, Wan 3.0 or Kling 3.0 and walks through a four-step rewrite. If Sora ran inside an AI agent, it points to Higgsfield MCP instead, which spends plan credits; the API has its own separate prepaid balance.

What is said

★ — how much it matters to the source.

  • ★★★ Higgsfield's blog says OpenAI removed the Sora 2 models and its Videos API on 24 September 2026, six months after announcing the deprecation, and named no replacement. · OpenAI, Sora 2
  • ★★ OpenAI published the Sora deprecation notice on 24 March 2026 and phased Sora out in two stages: the Sora website and apps closed on 26 April 2026, and the API followed on 24 September 2026, taking every sora-2 and sora-2-pro model with it, so calls to /v1/videos now return an error. · OpenAI, Sora, Sora 2
  • ★★★ Higgsfield's blog says Sora API requests do not work on other video APIs unchanged; the closest replacement keeps Sora's architecture of an asynchronous job, a status check or webhook and a file to download, so only the integration layer changes. · Sora 2, Sora
  • ★★★ Higgsfield's blog says moving from the Sora API to another single-model API fixes the outage but recreates the dependency of a whole feature on one model from one vendor. · Higgsfield API, Sora
  • ★★★ The Higgsfield API gives one key, one prepaid balance in US dollars and one request lifecycle for more than 50 current video and image models. · Higgsfield API
  • ★★ Video models in the Higgsfield API catalog as of October 2026 include Seedance 2.5, Kling 3.0 and Wan 3.0, and models of the MiniMax, LTX, PixVerse and Grok families. · Higgsfield API, Seedance 2.5, Kling 3.0, Wan 3.0, MiniMax, Grok Video
  • ★★ Image models in the Higgsfield API catalog as of October 2026 include Higgsfield's own Soul 2.0, Soul Cinema and Marketing Studio Image, and models from Recraft, Ideogram and Qwen. · Higgsfield API, Soul 2.0, Soul Cinema, Marketing Studio
  • ★★ On the Higgsfield API, switching models means changing the endpoint path and the body fields; polling, webhooks and file handling stay the same. · Higgsfield API
  • ★★★ On the Higgsfield API, Seedance 2.5 and Wan 3.0 generate clips up to 30 seconds at up to 1080p, and Kling 3.0 multi-shot scenes up to 15 seconds at up to 4K; all three produce audio. · Higgsfield API, Seedance 2.5, Wan 3.0, Kling 3.0, native audio
  • ★★ Higgsfield's blog says Sora 2 generated clips up to 20 seconds at 720p and Sora 2 Pro reached 1080p, both in 16:9 and 9:16. · Sora 2
  • ★★ For former Sora workloads Higgsfield recommends Seedance 2.5 for long clips with sound: audio comes in the same pass, and separate endpoints handle image-to-video, references, edits and extensions. · Seedance 2.5, native audio, image-to-video, Sora
  • ★★ Higgsfield recommends Kling 3.0 for multi-shot scenes, several shots in one request, with Standard, Pro, Turbo and 4K endpoints; the 4K endpoints serve work needing more than Sora 2 Pro's 1080p. · Kling 3.0, Sora 2
  • ★★ Higgsfield recommends Wan 3.0 for reference-driven clips, through text-to-video, image-to-video and reference-to-video endpoints with native audio. · Wan 3.0, native audio, image-to-video
  • ★★ Since every model of the Higgsfield API sits behind the same key, Higgsfield's blog suggests a pipeline that runs drafts on one model and finals on another, with one balance and one lifecycle. · Higgsfield API
  • ★★ Through the Higgsfield API, a Soul 2.0 or Marketing Studio Image request makes a character still or product shot whose URL goes straight into an image-to-video request on Seedance 2.5 or Kling 3.0. · Higgsfield API, Soul 2.0, Marketing Studio, Seedance 2.5, Kling 3.0, image-to-video
  • ★★ A Higgsfield API request goes to the model's own endpoint and returns a request id, a status url and a cancel url, where Sora returned a video object with an id and a status. · Higgsfield API, Sora
  • ★★ The Higgsfield API uses Sora's four job statuses (queued, in progress, completed, failed) and adds two final ones: nsfw for requests stopped by moderation and canceled for requests withdrawn while queued. · Higgsfield API, Sora 2, Sora
  • ★★ Moving a Sora request to the Higgsfield API changes three things: the model name moves from the body into the URL, the Bearer header becomes a Key header, and the form fields become a JSON body. · Higgsfield API, Sora 2, Sora
  • ★★ Sora's input reference moves to the Seedance 2.5 image-to-video endpoint of the Higgsfield API, which takes an image url and an optional end image url for the last frame. · Seedance 2.5, image-to-video, Sora, Higgsfield API
  • ★★ The Seedance 2.5 reference-to-video endpoint of the Higgsfield API accepts image, video and audio references in one request. · Seedance 2.5, Higgsfield API, image-to-video
  • ★ Sora's extensions and edits calls correspond to the Seedance 2.5 video-extend and video-edit endpoints of the Higgsfield API. · Seedance 2.5, Sora 2, Sora, Higgsfield API
  • ★★ The Higgsfield API is a separate product from a higgsfield.ai plan, with its own account for an individual or a company, a prepaid US-dollar balance and a minimum top-up of $5. · Higgsfield API
  • ★★ Higgsfield advises storing the Higgsfield API key, an ID and a secret shown in full only once, on the server and out of browser and mobile code. · Higgsfield API
  • ★ Official Python and TypeScript SDKs for the Higgsfield API are available alongside plain REST. · Higgsfield API
  • ★★ Higgsfield advises storing a Higgsfield API request id as soon as the request is accepted: it identifies the job for polling, cancellation, webhook deduplication and support requests. · Higgsfield API
  • ★★ For polling, Higgsfield advises checking the status url from the submit response with backoff, stopping at completed, failed, NSFW or canceled, and cancelling through the cancel url while still queued. · Higgsfield API
  • ★★ For webhooks, a Higgsfield API request carries the HTTPS endpoint, URL-encoded, as its hf webhook query parameter, replacing Sora's project-level webhooks. · Higgsfield API, Sora
  • ★★ A Higgsfield API webhook endpoint should reply with any 2xx status within ten seconds; network failures and 5xx responses are retried for up to two hours, and 4xx responses are final. · Higgsfield API
  • ★★ Since Higgsfield API webhook deliveries can repeat, Higgsfield advises deduplicating by request id and status, and reading the result from the status endpoint if delivery fails for good. · Higgsfield API
  • ★★ A finished Higgsfield API file stays at video.url for at least seven days, so Higgsfield advises a last pipeline step that copies it to one's own storage; Sora links expired within an hour. · Higgsfield API, Sora 2, Sora
  • ★★ Higgsfield API video models are priced per second of output, at a rate that depends on settings such as resolution and audio. · Higgsfield API
  • ★★ Higgsfield advises estimating cost before running: the Higgsfield API estimate endpoint takes the generation request's parameters and returns the cost without starting a job. · Higgsfield API
  • ★★ Failed Higgsfield API generations are not billed, and their cost returns to the balance automatically. · Higgsfield API · first in: 2026-09-16, How To Generate AI Videos Straight From the Higgsfield API
  • ★★ The Higgsfield API balance cannot go negative: new requests wait for a top-up, or auto top-up keeps production traffic running. · Higgsfield API
  • ★★★ If Sora ran as a tool inside Claude or another AI agent, Higgsfield's blog says Higgsfield MCP may fit better than the API: the agent connects through mcp.higgsfield.ai/mcp and signs in with a higgsfield.ai account, without an API key. (hedged) · Higgsfield MCP, Claude, Sora 2, Sora
  • ★ The Higgsfield plugin connects ChatGPT to Higgsfield the same way as Higgsfield MCP. · Higgsfield ChatGPT Plugin, ChatGPT, Higgsfield MCP
  • ★★ The higgsfield.ai lineup reachable through Higgsfield MCP includes Google Veo 3.1 alongside Seedance 2.5 at up to 1080p, Kling 3.0 and Wan 3.0; access to each model follows the account's plan. · Higgsfield MCP, Veo 3.1, Google, Seedance 2.5, Kling 3.0, Wan 3.0
  • ★★★ Generations through Higgsfield MCP spend plan credits at standard rates, since Unlimited access applies only on the higgsfield.ai website. · Higgsfield MCP, Higgsfield Unlimited, credit
  • ★ Results made through Higgsfield MCP appear in Assets on higgsfield.ai, tagged with the MCP source, next to work made in the interface. · Higgsfield MCP
  • ★★★ The Higgsfield API is a separate developer product with its own account and prepaid US-dollar balance; plan credits and Unlimited access from higgsfield.ai do not apply to API requests. · Higgsfield API, Higgsfield Unlimited, credit
  • ★★ Before switching production traffic from Sora, Higgsfield advises testing the migrated workflow in the Higgsfield API Playground. · Higgsfield API, Sora
  • ★★ n8n and Make have no native Higgsfield node and connect to the Higgsfield API through the standard HTTP Request step. · Higgsfield API
  • ★★ Sora 2 is no longer part of the Higgsfield model lineup; video work that ran on Sora can move to other models on higgsfield.ai such as Seedance 2.5, Kling 3.0 or Google Veo 3.1. · Sora 2, Seedance 2.5, Kling 3.0, Veo 3.1, Sora, Google
  • ★★ Creating a Higgsfield API key unlocks 20 concurrent requests, a limit that grows with the account's top-up volume. · Higgsfield API
