Wan 2.7

Overview

Wan 2.7 is an Alibaba video model for text-to-video, image-to-video, reference-guided generation, and video editing. Use this page when you are ready to call the API after trying the model in the APIXO playground.

Capability	Value
Model ID	`wan-2-7-video`
Modes	`text-to-video`, `image-to-video`, `reference-to-video`, `video-edit`
Prompt	Required for `text-to-video` and `reference-to-video`; optional for `image-to-video` and `video-edit`
Resolutions	`720p`, `1080p`
Aspect ratios	`16:9`, `9:16`, `1:1`, `4:3`, `3:4`
Mode-specific ratio rules	Default `16:9` for `text-to-video` and `reference-to-video`; not supported for `image-to-video`; optional for `video-edit`
Duration	`text-to-video`/`image-to-video`: `2-15` (default `5`); `reference-to-video`: `2-15` or `2-10` when any reference video is used (default `5`); `video-edit`: `0` or `2-10` (default `0`)
Public media fields	`image_urls`, `video_urls`, `audio_urls`

Public input contract

Public media input fields are image_urls, video_urls, and audio_urls.
Use audio_urls (not audio_url) for audio input.

Endpoint and authentication

Base URL:

https://api.apixo.ai/api/v1

Method	Endpoint	Purpose
`POST`	`/generateTask/wan-2-7-video`	Submit a generation or edit task
`GET`	`/statusTask/wan-2-7-video?taskId={taskId}`	Poll task status and retrieve results

All requests require your APIXO API key:

Authorization: Bearer YOUR_API_KEY

Submit requests also require:

Content-Type: application/json

Copy-paste async quickstart

This minimal request submits a text-to-video task and returns a taskId.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/wan-2-7-video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "async",
    "input": {
      "mode": "text-to-video",
      "prompt": "a cinematic rainy night in tokyo",
      "resolution": "1080p",
      "ratio": "16:9",
      "duration": 5
    }
  }'

Successful response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678"
  }
}

Save the taskId; you need it to poll for the final result.

Poll for result

curl -X GET "https://api.apixo.ai/api/v1/statusTask/wan-2-7-video?taskId=task_12345678" \

Webhook callback mode

Use callback mode when your backend should receive the final result automatically instead of polling.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/wan-2-7-video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "callback",
    "callback_url": "https://your-server.com/webhooks/apixo",
    "input": {
      "mode": "video-edit",
      "video_urls": [
        "https://example.com/input.mp4"
      ],
      "image_urls": [
        "https://example.com/reference.png"
      ],
      "prompt": "change the scene to watercolor style",
      "resolution": "1080p",
      "duration": 0,
      "audio_setting": "origin"
    }
  }'

See Webhooks for delivery requirements and retry behavior.

Billing

Wan 2.7 is billed per second. The selected resolution determines the unit price.

Resolution	APIXO official price
`720p`	`$0.08 / second`
`1080p`	`$0.12 / second`

Billing formulas:

Mode	Formula
`text-to-video`	`duration * unitPrice`
`image-to-video`	`duration * unitPrice`
`reference-to-video`	`duration * unitPrice`
`video-edit`	`billableSeconds * unitPrice`

For video-edit, billing is based on both input and output duration:

Input video duration must be greater than 0 and less than 11 seconds.
Billable input duration is capped at 10 seconds.
If duration = 0, then billableSeconds = cappedInputDuration * 2.
If duration = 2-10, then billableSeconds = cappedInputDuration + duration.
Maximum billable seconds for video-edit is 20.

For current route and market comparison pricing, see Pricing.

Latency and polling

Wan 2.7 tasks are asynchronous. The backend does not provide a fixed public latency SLA; actual latency varies by mode, resolution, duration, prompt complexity, media fetch speed, and provider queue load.

Workflow	Recommended first poll	Poll interval
`text-to-video`	30s after task creation	10s
`image-to-video`	30s after task creation	10s
`reference-to-video`	30s-45s after task creation	10s-15s
`video-edit`	45s-60s after task creation	10s-15s

For production workloads, use callback mode to avoid frequent polling on long-running video jobs.

Rate limits and concurrency can vary by account, API key, and route. If you receive 429, slow down requests and retry with backoff. For account-level details, see System APIs.

Errors and troubleshooting

HTTP errors

Code	Meaning	What to do
`400`	Invalid request body, mode, parameter, or media URL shape	Fix the request before retrying
`401`	Missing or invalid API key	Check the `Authorization` header
`402`	Insufficient balance or quota	Add balance or switch account/key
`403`	Key or route cannot access the model	Check permissions and route strategy
`429`	Rate limit or concurrency limit reached	Retry with exponential backoff
`500`	Server error	Retry with backoff
`502`	Upstream provider error	Retry with backoff
`504`	Upstream timeout	Retry or use callback mode

Task failure codes

failCode is route-dependent and may come from mapped upstream failures. Common values include:

Fail code	Meaning	What to do
`PromptInvalid`	Prompt is invalid or rejected by provider	Rewrite prompt and retry
`MissingParameter` / `BadRequest`	Required fields are missing or malformed	Check mode-specific required fields
`SensitiveContent` / `SensitiveContentDetected`	Prompt or media failed safety checks	Change prompt or media
`RateLimitExceeded`	Provider or route rate limit was reached	Retry with backoff
`Task TimeOut` / `Timeout`	Upstream generation timed out	Retry or use callback mode
`UnmappedUpstreamError`	Upstream error could not be mapped to a known type	Retry with backoff or contact support with `taskId`

Parameter troubleshooting

mode must be one of text-to-video, image-to-video, reference-to-video, video-edit.
prompt is required for text-to-video and reference-to-video.
ratio is not allowed in image-to-video.
image-to-video requires image_urls or video_urls.
If image-to-video includes video_urls, audio_urls is not allowed.
reference-to-video requires at least one reference item across image_urls and video_urls, with total count <= 5.
If reference-to-video includes audio_urls, its length must equal image_urls + video_urls.
video-edit requires exactly one video_urls item.
video-edit input clip duration must be greater than 0 and less than 11 seconds.
