⚡ Async Image Generation API

Submit a task and get a task_id, then poll the status endpoint until generation completes.

Step 1 — Submit Async Task

POST https://vinano.ai/api/v1/images/async

Step 2 — Poll Task Status

GET https://vinano.ai/api/v1/images/task-status?task_id={task_id}

# Step 1: Submit async task (same parameters as sync API)
curl -X POST "https://vinano.ai/api/v1/images/async" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -F "prompt=a beautiful sunset" \
  -F "model=gemini-2.5-flash-image-preview"

# Response (202):
# {
#   "status": 202,
#   "task_id": "550e8400-e29b-41d4-a716-446655440000",
#   "message": "Task submitted. Use GET /api/v1/images/task-status?task_id={task_id} to poll for results.",
#   "model": "gemini-2.5-flash-image-preview",
#   "credits": { "cost": 10 }
# }

# Step 2: Poll task status (repeat every 3-5s until status=200)
curl -X GET "https://vinano.ai/api/v1/images/task-status?task_id=550e8400-e29b-41d4-a716-446655440000" \

Best Practices

Keep API Token Safe

Do not share your API Token with others or expose it in code repositories

Implement Error Handling

Handle all possible error codes, especially 429 (rate limit) and 495 (insufficient credits)

Monitor Rate Limit Headers

Check X-RateLimit-Remaining in response headers to understand remaining quota

Implement Retry Mechanism

For 429 errors, implement exponential backoff retry based on Retry-After header

Optimize Prompts

Clear, specific prompts yield better generation results

Compress Images

Compressing images before upload improves transfer speed and saves bandwidth

API Rate Limit

API calls are protected by rate limiting, limits vary by subscription plan:

年

Yearly Advanced Plan

200 requests/minute

月

Monthly Advanced Plan

20 requests/minute

💡Response headers will include X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset information
