Overview
Background Remover runs the U2-Net salient object segmentation model on our own infrastructure, so your images are never sent to a third-party AI provider. It works best on photos with one clear subject, such as products, people, pets and vehicles, and returns a download URL for the finished PNG.

Endpoint
One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.
curl -X POST https://api.apiverve.com/v1/backgroundremover \
-H "x-api-key: your_api_key_here" \
-H "Content-Type: application/json" \
-d '{
"url": "https://upload.wikimedia.org/wikipedia/commons/2/26/YellowLabradorLooking_new.jpg",
"bgColor": "#ffffff"
}'const res = await fetch('https://api.apiverve.com/v1/backgroundremover', {

'x-api-key': 'your_api_key_here',

}Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.
Authentication
Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.
A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.
Parameters
Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them.
| Parameter | Type | Description |
|---|---|---|
imageRequired | string | Image file upload (JPG, PNG, GIF, WebP, BMP supported, max 10MB) |
bgColorOptional | string | Optional hex color to fill the background with (e.g. #ffffff). Omit for a transparent background. hexColor |
Response
Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.
{
"status": "ok",
"error": null,
"data": {
"id": "3f6c2a91-7d4e-4b8a-9c21-5e0d8b7a6f13",

"height": 577,
"background": "transparent",

},
"code": 200
}
Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
id | string | "3f6c2a91-7d4e-4b8a-9c21-5e0d8b7a6f13" | Unique identifier for the generated image file |
width | number | 700 | Width of the output image in pixels (same as the input) |
height | number | 577 | Height of the output image in pixels (same as the input) |
background | string | "transparent" | Background applied: "transparent" or the hex color used |
foregroundRatioPremium | number | 0.3778 | Share of the image kept as foreground, from 0 to 1 |
outputSizePremium | number | 806519 | File size in bytes of the output PNG |
mimeType | string | "image/png" | MIME type of the output file (always image/png) |
expires | number | 1761000000000 | Unix timestamp in milliseconds when the download URL expires |
downloadURL | string | "https://storage.googleapis.com/apiverve/backgroundremover/3f6c2a91-7d4e-4b8a-9c21-5e0d8b7a6f13.png" | Direct URL to download the output PNG |
Errors
Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted | A key restriction or IP allow-list; see key scoping. |
429 | Rate limited, or out of credits | Read error to tell them apart; see rate limits. |
Use cases
- Marketplace Product Listings
- Sellers upload phone photos of items and the listing tool swaps the cluttered background for plain white before the product page goes live.
- Profile Photo Cleanup
- Team directories cut employees out of casual snapshots and place them on a consistent brand color so every profile card matches.
- Sticker and Design Tools
- Design apps let users drop a photo onto a canvas and get the subject back as a transparent PNG they can layer, resize and recolor.
- Catalog Image Pipelines
- Retail catalog jobs batch-process supplier photos into transparent cutouts so merchandisers can composite them onto seasonal banners.
