Available Commands

All generation and edit tasks are asynchronous: submit a task, get a task_id, then poll for results.

Generate Image

Step 1: Submit task

curl -s -X POST "https://creaa.ai/api/open/v1/images/generate" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-Source: openclaw" \
  -d '{
    "prompt": "<user prompt here>",
    "model": "<model_id>",
    "aspect_ratio": "<ratio>",
    "n": <count>
  }'

Parameters:

• prompt (required): Image description
• model (optional): Model ID from the image models table above. Default: nano-banana-2
• aspect_ratio (optional): Aspect ratio like 1:1, 16:9, 9:16. Must match the model's supported ratios. Default varies by model.
• n (optional): Number of images, 1-4. Default 1

Response:

{
  "success": true,
  "task_id": "abc123-def456",
  "task_type": "image",
  "model": "nano-banana-2"
}

Step 2: Poll status (wait 5-10 seconds between polls for images)

curl -s "https://creaa.ai/api/open/v1/tasks/<task_id>" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "X-Source: openclaw"

Status Response (completed):

{
  "success": true,
  "task_id": "abc123-def456",
  "status": "completed",
  "progress": 1.0,
  "result_url": "https://...",
  "result_urls": ["https://...", "https://..."]
}

Image generation typically takes 10-60 seconds. Poll every 5 seconds.

Edit Image

Use this endpoint for:

• Single-image edit: image_url or image_data (base64)
• Multi-image reference edit / composition: image_urls or image_data_list (base64)

Step 1: Submit task (with URL)

curl -s -X POST "https://creaa.ai/api/open/v1/images/edit" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-Source: openclaw" \
  -d '{
    "prompt": "<edit prompt here>",
    "image_url": "https://...",
    "model": "<model_id>",
    "aspect_ratio": "<ratio>",
    "n": <count>
  }'

Step 1: Submit task (with base64 image data)

curl -s -X POST "https://creaa.ai/api/open/v1/images/edit" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-Source: openclaw" \
  -d '{
    "prompt": "<edit prompt here>",
    "image_data": "data:image/png;base64,iVBOR...",
    "model": "<model_id>",
    "aspect_ratio": "<ratio>",
    "n": <count>
  }'

Single-image edit parameters:

• prompt (required): Edit instruction
• image_url (option A): Public source image URL
• image_data (option B): Base64-encoded image data. Supports data:image/png;base64,... prefix or raw base64 string. Max 20MB.
• model (optional): Model ID from the image models table above. Default: nano-banana-2
• aspect_ratio (optional): Must match the model's supported ratios
• n (optional): Number of output images, 1-4. Default 1

Provide either image_url or image_data for single-image edit. If both are provided, image_url takes priority.

Multi-image edit / composition example:

curl -s -X POST "https://creaa.ai/api/open/v1/images/edit" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-Source: openclaw" \
  -d '{
    "prompt": "<combine these references into one result>",
    "image_urls": ["https://...", "https://..."],
    "model": "nano-banana-2",
    "aspect_ratio": "16:9",
    "n": 1
  }'

You can also use image_data_list with base64 strings instead of image_urls.

Multi-image edit notes:

• image_urls or image_data_list: 2-N images, where N depends on the model
• Max reference images by model:

- seedream-5.0: up to 4 input images - nano-banana-2: up to 14 input images - nano-banana-pro: up to 10 input images - gpt-image-1.5: up to 10 input images

• Only models with multi_image_edit capability support this mode
• URLs must be public http(s) URLs; base64 data is uploaded to storage automatically

Response:

{
  "success": true,
  "task_id": "abc123-def456",
  "task_type": "image_edit",
  "model": "nano-banana-2"
}

Step 2: Poll status

curl -s "https://creaa.ai/api/open/v1/tasks/<task_id>" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "X-Source: openclaw"

Status Response (completed):

{
  "success": true,
  "task_id": "abc123-def456",
  "status": "completed",
  "progress": 1.0,
  "result_url": "https://...",
  "result_urls": ["https://...", "https://..."]
}

Image editing typically takes 10-90 seconds. Poll every 5 seconds.

Generate Video

Step 1: Submit task

curl -s -X POST "https://creaa.ai/api/open/v1/videos/generate" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "X-Source: openclaw" \
  -d '{
    "prompt": "<user prompt here>",
    "model": "<model_id>",
    "mode": "<text_to_video|image_to_video>",
    "duration": <seconds>,
    "aspect_ratio": "<ratio>"
  }'

Parameters:

• prompt (required): Video description

• image_url (option A, required for image_to_video): URL of the source image
• image_data (option B, required for image_to_video): Base64-encoded image data. Supports data:image/png;base64,... prefix or raw base64 string. Max 20MB.
• duration (optional): Duration in seconds, must match the model's supported durations. Default varies by model.
• aspect_ratio (optional): e.g. 16:9, 9:16, 1:1. Must match the model's supported ratios.

For image_to_video mode, provide either image_url or image_data. If both are provided, image_url takes priority.

Response:

{
  "success": true,
  "task_id": "abc123-def456",
  "task_type": "video",
  "model": "veo-3.1"
}

Step 2: Poll status (wait 15 seconds between polls for videos)

curl -s "https://creaa.ai/api/open/v1/tasks/<task_id>" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "X-Source: openclaw"

Status Response (completed):

{
  "success": true,
  "task_id": "abc123-def456",
  "status": "completed",
  "progress": 1.0,
  "result_url": "https://..."
}

Status values: pending -> processing -> completed or failed. Video generation typically takes 60-300 seconds. Poll every 15 seconds.

Unified Task Status Endpoint

Image generation, image edit, and video tasks all use the same status endpoint:

curl -s "https://creaa.ai/api/open/v1/tasks/<task_id>" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "X-Source: openclaw"

Keep polling until status is completed or failed.

• For images: poll every 5 seconds
• For videos: poll every 15 seconds

List Available Models

curl -s "https://creaa.ai/api/open/v1/models" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "X-Source: openclaw"

Returns full model catalog with pricing, supported aspect ratios/durations, capabilities, and max_upload_images for image-edit models.

Check Usage

curl -s "https://creaa.ai/api/open/v1/usage" \
  -H "Authorization: Bearer $CREAA_API_KEY" \
  -H "X-Source: openclaw"

Usage is tracked against the API key's own credit pool (api_credits), not the website account balance.

Billing Notes

• Open API requests charge the API key credit pool, not the user's main website balance.
• If task submission fails before the job is queued, credits are refunded immediately.
• If a queued task fails, credits are refunded automatically.
• For image generation and image editing, partial success is billed by successful outputs; unused credits are refunded automatically.
• For video generation, successful jobs keep the full charge; failed jobs are refunded in full.

Error Handling

If any API call returns "success": false, display the error message to the user. Common errors:

• invalid_api_key: The API key is missing or wrong. User should check their key at https://creaa.ai/profile
• rate_limit_exceeded: Too many requests per minute. Wait and retry.
• Insufficient credits: Not enough credits. User should top up at https://creaa.ai/pricing
• Only public http(s) image URLs are allowed: The image URL points to localhost, private network, or a non-http(s) source.
• Model <id> does not support multi_image_edit: The requested model can edit a single image but cannot do multi-image composition.
