Image-conditioned models accept either imageDataUrl (base64) or a public imageUrl. The service uses the explicit value you provide before checking any saved attachments.

Overview

POST /generate-video submits an asynchronous job to create, extend, or edit a video. The endpoint responds immediately with runId, id, model, and status: "pending". runId and id are the same NanoGPT job identifier (format vid_...). Poll the unified Video Status endpoint with that job ID until you receive final assets. Duration-based billing is assessed after completion. Errors include descriptive JSON payloads. Surface the error.message (and HTTP status) to help users correct content-policy or validation issues.

Extend Workflows

Midjourney extend (task-based): use POST /api/generate-video/extend with runId (preferred) or taskId (legacy alias) plus index (0-3). This flow does not accept video, videoUrl, videoDataUrl, or videoAttachmentId.
Source video extend (extend models): use POST /api/generate-video with an extend model plus prompt and a source video (videoUrl, videoDataUrl, or videoAttachmentId). video is only accepted by select models (for example, wan-wavespeed-25-extend). Max source video length: 120 seconds.

Request Schema

Only include the fields required by your chosen model. Unknown keys are ignored, but some models fail when extra media fields are present.

Core Fields

field	type	required	details
`model`	string	yes	Video model ID. Model availability changes; discover models via `GET /api/v1/models?detailed=true`.
`conversationUUID`	string	no	Attach the request to a conversation thread.
`prompt`	string	conditional	Required for text-to-video and edit models unless a structured script is supplied.
`negative_prompt`	string	no	Suppresses specific content. Respected by Veo, Wan, Runway, Pixverse, and other models noted below.
`script`	string	conditional	LongStories models accept full scripts instead of relying on `prompt`.
`storyConfig`	object	conditional	LongStories structured payload (e.g. scenes, narration, voice).

Model Discovery

Video model IDs and supported fields change over time. Use GET /api/v1/models?detailed=true to discover the current list and select a model intended for video generation. Notes:

Different models accept different media inputs (for example imageUrl vs a source videoUrl) and may support different duration / resolution options.
If you see validation errors, first retry with only the minimal required fields for your chosen model.

Async Processing & Status Polling

The submission response includes { runId, id, model, status: "pending" } where id and runId are identical.
Poll /api/video/status?requestId=<runId> (or runId) until the job reaches status: "COMPLETED" or status: "FAILED". The legacy /api/generate-video/status endpoint is deprecated.
Many jobs emit intermediate states (queued, processing, generating, delivering). Persist them if you need audit trails.
Failed jobs include an error object. Surface the message and adjust prompts or inputs before retrying.
Duration and resolution determine credit usage.

Response example

{
  "runId": "vid_m1abc123def456",
  "id": "vid_m1abc123def456",
  "status": "pending",
  "model": "veo2-video",
  "cost": 0.35,
  "paymentSource": "XNO",
  "remainingBalance": 12.5,
  "prechargeLabel": "string"
}

Content & Safety Notes

Some models may block prompts that violate content policies. Non-200 responses describe the violation reason; relay these messages verbatim to users or implement automated prompt adjustments.

Next Steps

Poll the Video Status endpoint after every submission to retrieve final assets.
Keep customer-facing pricing tables in sync with the API behavior you observe in production.
