Endpoint and authentication

Base URL:

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

Method	Endpoint	Purpose
`POST`	`/generateTask/wan-2-6-video`	Submit a generation task
`GET`	`/statusTask/wan-2-6-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-2-6-video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "async",
    "input": {
      "mode": "text-to-video",
      "prompt": "a cinematic fox walking through neon rain",
      "resolution": "720p",
      "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-2-6-video?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://r2.apixo.ai/video.mp4\"]}",
    "createTime": 1767965610929,
    "completeTime": 1767965752317,
    "costTime": 141388

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;

curl -X POST "https://api.apixo.ai/api/v1/generateTask/wan-2-6-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": "image-to-video-flash",
      "prompt": "make the character speak with subtle camera motion",
      "image_urls": [

      ],
      "resolution": "720p",
      "duration": 5,
      "sound": false
    }
  }'

See Webhooks for delivery requirements and retry behavior.

Billing

Wan 2.6 is billed per second. Total cost is duration * unitPrice. Standard (non-flash) modes:

Mode	Resolution	APIXO official price
`text-to-video`, `image-to-video`, `reference-to-video`	`720p`	`$0.10 / second`
`text-to-video`, `image-to-video`, `reference-to-video`	`1080p`	`$0.15 / second`

Flash modes:

Mode	Resolution	`sound=false`	`sound=true`
`image-to-video-flash`, `reference-to-video-flash`	`720p`	`$0.025 / second`	`$0.05 / second`
`image-to-video-flash`, `reference-to-video-flash`	`1080p`	`$0.0375 / second`	`$0.075 / second`

For current route and market comparison pricing, see Pricing.

Latency and polling

Wan 2.6 tasks are asynchronous. The backend does not provide a fixed public latency SLA; actual latency varies by mode, duration, resolution, 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` / `image-to-video-flash`	30s after task creation	10s
`reference-to-video` / `reference-to-video-flash`	45s 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 the 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 exponential backoff
`Task TimeOut` / `Timeout`	Upstream generation timed out	Retry or use callback mode
`UnmappedUpstreamError`	Upstream error could not be mapped to a known category	Retry with backoff or contact support with the `taskId`

Parameter troubleshooting

prompt is required and must be non-empty for all modes.
image-to-video-flash and image-to-video require exactly one image_urls item.
reference-to-video-flash and reference-to-video require reference_urls with 1-5 items.
sound is valid only for flash modes.
duration defaults to 5, but reference modes only allow up to 10.
In flash modes, when sound=false, optional audio input is ignored.
