Endpoint and authentication

Base URL:

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

Method	Endpoint	Purpose
`POST`	`/generateTask/hailuo-2-3`	Submit a generation task
`GET`	`/statusTask/hailuo-2-3?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 standard text-to-video task and returns a taskId.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/hailuo-2-3" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "async",
    "input": {
      "mode": "standard-text-to-video",
      "prompt": "a dramatic sunrise over a futuristic skyline with slow cinematic camera movement",
      "duration": 6
    }
  }'

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/hailuo-2-3?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": 1767965730929,
    "costTime": 120000
  }
}

Failed response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678",
    "state": "failed",
    "failCode": "PromptInvalid",
    "failMsg": "Prompt is invalid or rejected by provider",
    "createTime": 1767965610929,
    "completeTime": 1767965620132,
    "costTime": 9041
  }
}

Parse resultJson after state becomes success:

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

Request body

{
  "request_type": "async",
  "input": {
    "mode": "standard-text-to-video",
    "prompt": "a dramatic sunrise over a futuristic skyline with slow cinematic camera movement",
    "duration": 6
  }
}

Standard image-to-video

{
  "request_type": "async",
  "input": {
    "mode": "standard-image-to-video",
    "prompt": "make this still image move naturally with cinematic camera motion",
    "image_urls": [
      "https://example.com/input.jpg"
    ],
    "duration": 10
  }
}

Pro text-to-video

{
  "request_type": "async",

    "mode": "pro-text-to-video",
    "prompt": "a premium commercial shot of a glass perfume bottle with elegant camera movement"
  }
}

Pro image-to-video

{
  "request_type": "async",
  "input": {
    "mode": "pro-image-to-video",
    "prompt": "smoothly animate this image with a subtle camera push-in and natural lighting variation",
    "image_urls": [
      "https://example.com/input.jpg"
    ]
  }
}

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

Hailuo 2.3 input parameters.

Show properties

string

required

Generation mode. Supported values: standard-text-to-video, standard-image-to-video, pro-text-to-video, pro-image-to-video.

string

required

Text prompt describing the video. Must be a non-empty string and no more than 2,000 UTF-8 bytes.

string[]

Required for standard-image-to-video and pro-image-to-video. The backend requires exactly 1 non-empty image URL. Text-to-video modes ignore this field.

integer|string

Required for standard modes. Supported values: 6, 10, "6", or "10". Pro modes have a fixed 5-second output and ignore duration if it is present.

Mode	Required media	`duration` behavior	Output
`standard-text-to-video`	None	Required: `6` or `10` seconds	`768p` video
`standard-image-to-video`	Exactly 1 image URL	Required: `6` or `10` seconds	`768p` video
`pro-text-to-video`	None	Ignored	Fixed 5-second `1080p` video
`pro-image-to-video`	Exactly 1 image URL	Ignored	Fixed 5-second `1080p` video

Image-to-video uses the provided image as the first frame. Use a direct JPG, JPEG, or PNG URL; upstream validation may reject images over 20MB, images whose short side is 300px or smaller, or images outside the 2:5 to 5:2 aspect-ratio range.

Response format

Submit task response

POST /generateTask/hailuo-2-3 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: processing, success, or failed.

string

JSON string containing generated video URLs in resultUrls. 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 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/hailuo-2-3" \
  -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": "pro-image-to-video",
      "prompt": "animate this product image with a clean studio camera move",
      "image_urls": [
        "https://example.com/product.jpg"
      ]
    }
  }'

The callback payload mirrors the final status response shape with code, message, and data. See Webhooks for delivery requirements and retry behavior.

Billing

Hailuo 2.3 billing depends on the selected mode family.

Mode family	APIXO price	Billing rule	Example charge
Standard modes	`$0.056 / second`	`duration * $0.056`	6s: `$0.336`; 10s: `$0.56`
Pro modes	`$0.49 / use`	Fixed price per generation	Fixed 5-second output: `$0.49`

For current route and market comparison pricing, see Pricing.

Latency and polling

Actual latency may vary by prompt complexity, image accessibility, mode, provider queue load, and upstream processing time. The status response reports costTime in milliseconds after completion when timing data is available.

Mode family	Output duration	Recommended first poll	Poll interval
Standard modes	6s or 10s	30s after task creation	10s-15s
Pro modes	Fixed 5s	45s-60s after task creation	10s-15s

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

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, missing `input`, unsupported `mode`, invalid `duration`, or invalid image 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 or unknown upstream failure	Retry with backoff
`502`	Upstream provider error	Retry with backoff
`504`	Upstream timeout	Retry or use callback mode for long-running jobs

Validation notes

Condition	Backend behavior
Missing `input`	Request fails before task creation
Missing or empty `prompt`	Request fails before task creation
Unsupported `mode`	Request fails before task creation
Image mode without `image_urls`	Request fails before task creation
`image_urls` contains 0 or more than 1 item	Request fails before task creation
Standard mode without `duration`	Request fails before task creation
Standard mode with duration other than `6` or `10`	Request fails before task creation
Pro mode with `duration`	`duration` is ignored

Task failure codes

Fail code	Meaning	What to do
`PromptInvalid`	Prompt was rejected or malformed	Adjust the prompt and retry
`SensitiveContent` / `InputOutputSensitiveContentDetected`	Prompt, input image, or output failed content checks	Change the prompt or input image
`ImageFormatIncorrect` / `InvalidImageSize`	Input image failed upstream image validation	Use a public JPG/JPEG/PNG URL within the documented size and aspect-ratio limits
`RateLimited`	Provider-side rate limit	Retry with exponential backoff
`Timeout`	Provider-side timeout	Retry, simplify the request, or use callback mode
`Unknown error`	Provider returned an unmapped failure	Retry with backoff or contact support with the `taskId`
