Quickstart

Create images and videos with the same async OpenAPI contract.

Step 1: Get an API key

Register
Open API keys
Create a key and store it securely (shown once)

Step 2: Top up

Open Recharge
Complete payment before calling the API

Step 3: Note the base URL

The console shows a base URL like (origin only, no path):

https://sigrunai.com

API paths start with /v1. Auth: Authorization: Bearer <API Key>.

Image example (GPT Image 2)

curl -X POST 'https://sigrunai.com/v1/images' \
  -H 'Authorization: Bearer sk_xxx' \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "gpt-image-2",
    "prompt": "A golden retriever running in sunlight, photorealistic",
    "quality": "medium",
    "n": 1
  }'

Video example (Seedance 2.0 MD)

curl -X POST 'https://sigrunai.com/v1/videos' \
  -H 'Authorization: Bearer sk_xxx' \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "seedance2.0-md",
    "prompt": "A cat running on grass, tracking shot",
    "duration": 5,
    "aspect_ratio": "16:9"
  }'

Success responses look like { "code": 20000, "msg": "...", "data": { "task_id": "...", "status": "queued", ... } }.

Step 4: Poll the task

curl -X GET 'https://sigrunai.com/v1/images/{task_id}' \
  -H 'Authorization: Bearer sk_xxx'

For video, use /v1/videos/{task_id}. When status is completed, read data.result.image_url or data.result.video_url.
