Why developers choose this background remover API

Quick start — one API call removes any background

Sign up, copy your key from the dashboard, and POST your image. The endpoint returns a generation_id; poll until status=completed, then download the transparent PNG from output_url.

curl -X POST https://api.pixelapi.dev/v1/image/remove-background \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]"
# Response: {"generation_id": "uuid", "status": "queued", ...}

# Poll until completed
curl https://api.pixelapi.dev/v1/image/UUID \
  -H "Authorization: Bearer YOUR_API_KEY"
# Response: {"status": "completed", "output_url": "https://..."}

# Optional: request WebP output with a white background fallback
curl -X POST https://api.pixelapi.dev/v1/image/remove-background \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]" \
  -F "output_format=webp"

Comparison vs alternatives

Rate limits & error handling

Default 60 requests/minute on the free tier, 600 on paid tiers. Exceeding the limit returns HTTP 429 with a Retry-After header. The recommended retry strategy is exponential backoff starting at 2 seconds, doubling on each retry up to 30 seconds. The Python and Node SDKs implement this automatically.

# Python SDK auto-retries 429 with exponential backoff
from pixelapi import PixelAPI
client = PixelAPI(api_key="...", max_retries=4)
result = client.remove_background(image="bulk_product.jpg") # retries handled

Other notable HTTP responses:

• 400 Bad Request — image format unsupported or payload missing. Check the error field in the response body.
• 402 Payment Required — insufficient credits. Top up from the dashboard or set up auto-recharge.
• 413 Payload Too Large — image exceeds the 50 MP / 20 MB limit.
• 500 Internal Server Error — transient error; retry with backoff. Credits are never deducted on server errors.
