How this service works
HALOWERK medienwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A base64-encoded PNG or WebP image with a real alpha channel (background made transparent), along with the fraction of the frame that survived removal, the bounding box of the remaining subject, and optionally a version cropped to that bounding box.
Example use cases
E-commerce product photo cutout
“I have a product image at https://myshop.com/images/mug.jpg — strip the background and return a PNG with a transparent alpha channel so I can drop it onto any color backdrop in my store.”
Portrait subject isolation
“Take this headshot I'm sending as base64 and remove the background, returning a WebP with true transparency and the bounding box coordinates so I know where the face is in the frame.”
Privacy-safe local background removal
“Remove the background from this confidential document scan — I need it done locally with no data leaving our systems. Return the result as a PNG cropped to just the subject.”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/bg-remove?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when privacy is critical (no image data leaves the server, no third-party provider sees the image), when cost matters ($0.01 per call with no subscription), or when you need bounding-box metadata alongside the transparent image. Choose it over cloud providers like remove.bg or Photoroom when data retention restrictions apply.
Side effects
- Image URL is unreachable or returns a non-image content type
- Base64 payload is malformed or too large
- Unsupported image format submitted
- Subject detection fails (very low contrast or ambiguous scenes), resulting in poor cutout quality
- Timeout on very large or high-resolution images
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| format | string | Output format. Both carry an alpha channel; WebP is markedly smaller. |
| source | object | The image. Either url or content_base64. |
| quality | integer | For WebP output. |
| max_width | integer | Scale the result down so the width fits. Never scales up. |
| alpha_matting | boolean | Refine the edge for hair and fur. Slower, and not always better — compare before using it by default. |
| crop_to_subject | boolean | Crop the result to the bounding box of what remained. |
