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

Method	Endpoint	Purpose
`POST`	`/generateTask/wan-2-2-animate`	Submit a generation task
`GET`	`/statusTask/wan-2-2-animate?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 an animate task and returns a taskId.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/wan-2-2-animate" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "async",
    "input": {
      "mode": "standard",
      "type": "animate",
      "image_urls": [
        "https://example.com/character.png"
      ],
      "video_urls": [
        "https://example.com/motion.mp4"
      ],
      "resolution": "480p",
      "seed": -1
    }
  }'

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-2-2-animate?taskId=task_12345678" \
  -H "Authorization: Bearer YOUR_API_KEY"

Processing response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678",
    "state": "processing",
    "createTime": 1767965610929
  }
}

Success response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678",
    "state": "success",
    "resultJson": "{\"resultUrls\":[\"https://file.apixo.ai/video.mp4\"]}",
    "createTime": 1767965610929,
    "completeTime": 1767965772317,
    "costTime": 161388
  }
}

Failed response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678",
    "state": "failed",
    "failCode": "PromptInvalid",

    "createTime": 1767965610929,
    "completeTime": 1767965620132
  }
}

Parse resultJson after state becomes success:

const payload = JSON.parse(data.resultJson);
const videoUrls = payload.resultUrls;

Request body

Animate

Use type: "animate" to animate the character in the source image with motion from the reference video.

{
  "request_type": "async",
  "input": {
    "mode": "standard",
    "type": "animate",
    "image_urls": [
      "https://example.com/character.png"

    "resolution": "480p",
    "seed": -1
  }
}

Replace

Use type: "replace" to replace the character in the motion video with the character from the source image.

{
  "request_type": "async",
  "input": {
    "mode": "standard",
    "type": "replace",
    "image_urls": [
      "https://example.com/character.png"

}

Parameters

string

default:"async"

Result delivery mode. Use async for polling with statusTask, or callback for webhook delivery.

string

Required when request_type is callback. Must be a public HTTPS URL that can receive the final task payload. See Webhooks.

object

required

Wan 2.2 Animate input parameters.

Show properties

string

required

Public generation mode. Supported value: standard.

string

default:"animate"

Animation behavior. Supported values: animate, replace.

string[]

required

Source image URLs. Provide exactly 1 URL.

string[]

required

Motion reference video URLs. Provide exactly 1 public HTTP/HTTPS MP4, MOV, or M4V URL. APIXO probes video_urls[0] to detect billing duration before submitting the task.

string

Optional prompt guidance. If provided, it must be a non-empty string.

string

default:"480p"

Output resolution. Supported values: 480p, 720p.

integer

default:"-1"

Random seed. Use -1 for a random seed, or set an integer from 0 to 2147483647 for reproducible runs.

Response format

Submit task response

POST /generateTask/wan-2-2-animate returns a task ID when the task is accepted:

integer

API status code. 200 means the task was accepted.

string

Human-readable status message.

string

Unique task identifier used with the status endpoint.

Status response fields

string

Unique task identifier.

string

Current task state: pending, processing, success, or failed.

string

JSON string containing the generated video URLs. Present when state is success.

string

Machine-readable failure code. Present when state is failed.

string

Human-readable failure message. Present when state is failed.

integer

Task creation timestamp in Unix milliseconds.

integer

Task completion timestamp in Unix milliseconds. Present after completion.

integer

Processing duration in milliseconds. Present after successful completion when timing data is available.

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-2-2-animate" \
  -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": "standard",
      "type": "replace",
      "image_urls": [
        "https://example.com/character.png"
      ],
      "video_urls": [
        "https://example.com/motion.mp4"
      ],
      "prompt": "replace the person in the motion video with the provided character",
      "resolution": "720p",
      "seed": 42
    }
  }'

See Webhooks for delivery requirements and retry behavior.

Billing

Wan 2.2 Animate is billed per generated video second. The selected resolution determines the unit price, and billable duration is detected from video_urls[0].

Resolution	Billing input	APIXO price
`480p`	Detected reference video duration, minimum 5 seconds and maximum 120 billable seconds	`$0.04 / second`
`720p`	Detected reference video duration, minimum 5 seconds and maximum 120 billable seconds	`$0.08 / second`

If the reference video is shorter than 5 seconds, billing uses 5 seconds. If it is longer than 120 seconds, billing is capped at 120 seconds. For current route and market comparison pricing, see Pricing.

Latency and polling

Actual latency may vary by reference video duration, resolution, queue load, and current route health.

Request shape	Typical generation time	Recommended first poll	Poll interval
Short `480p` animation	Varies with reference video duration and queue load	60s after task creation	5s-10s
Short `720p` animation	Varies with reference video duration and queue load	60s after task creation	5s-10s
Longer reference video	Varies with reference video duration and queue load	60s-120s after task creation	10s

Video generation can take several minutes. For production workloads, use callback mode to avoid frequent polling.

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, image URL, or video URL	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, or content was rejected	Check permissions and revise input content
`429`	Rate limit or concurrency limit reached	Retry with exponential backoff
`500`	Server error	Retry with backoff
`502`	Upstream service error	Retry with backoff
`504`	Upstream timeout	Retry or use callback mode for long-running jobs

Task failure causes

Cause	What to check
Content policy rejection	Revise the prompt, source image, or motion video
Invalid mode or type	Use `mode: "standard"` and `type: "animate"` or `"replace"`
Invalid media shape	Provide exactly 1 `image_urls` item and exactly 1 `video_urls` item
Video URL cannot be probed	Use a direct public HTTP/HTTPS MP4, MOV, or M4V URL that supports range reads or full download
Invalid resolution	Use `480p` or `720p`
Invalid seed	Use `-1` or an integer from `0` to `2147483647`
Upstream rate limit or timeout	Retry with backoff or switch to callback mode

Common fixes

Symptom	Fix
Request fails with invalid mode	Set `input.mode` to `standard`
Request fails before task creation	Check that `video_urls[0]` is publicly reachable and has a supported MP4, MOV, or M4V media type
Billing is higher than expected for a very short video	Videos shorter than 5 seconds are billed as 5 seconds
Billing stops increasing for a long reference video	Billable duration is capped at 120 seconds
No update for several minutes	Continue polling with backoff, or use callback mode for production
