Cheapest Background Eraser API

A production REST API that erases the background from any image and returns a clean transparent PNG. The cheapest background eraser API with a publicly listed per-image price — $0.0025 per image, 8× cheaper than what Photoroom charges. One POST call. Transparent PNG back in 1–3 seconds. 24-hour free trial (up to 5,000 credits), no credit card.

Quick start — erase a background in one call

Sign up, grab your API 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.

# Step 1 — submit image
curl -X POST https://api.pixelapi.dev/v1/image/remove-background \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]"
# {"generation_id": "abc123", "status": "queued"}

# Step 2 — poll until completed
curl https://api.pixelapi.dev/v1/image/abc123 \
  -H "Authorization: Bearer YOUR_API_KEY"
# {"status": "completed", "output_url": "https://...cutout.png"}

# Step 3 — download transparent PNG
curl -o product_cutout.png "https://...cutout.png"

pip install pixelapi

from pixelapi import PixelAPI

client = PixelAPI(api_key="YOUR_API_KEY")
result = client.remove_background(image="product.jpg")
result.save("product_cutout.png") # transparent PNG

npm install pixelapi
---
import { PixelAPI } from "pixelapi";

const client = new PixelAPI({ apiKey: process.env.PIXELAPI_KEY });
const result = await client.removeBackground({ image: "./product.jpg" });
await result.save("product_cutout.png"); // transparent PNG

composer require pixelapi/pixelapi

<?php
use PixelAPI\Client;

$client = new Client(getenv("PIXELAPI_KEY"));
$result = $client->removeBackground(["image" => "product.jpg"]);
file_put_contents("product_cutout.png", $result->getBody());

gem install pixelapi
---
require "pixelapi"

client = PixelAPI::Client.new(api_key: ENV["PIXELAPI_KEY"])
result = client.remove_background(image: "product.jpg")
File.binwrite("product_cutout.png", result.body)

go get github.com/pixelapi/pixelapi-go

import "github.com/pixelapi/pixelapi-go"

client := pixelapi.New("YOUR_API_KEY")
result, err := client.RemoveBackground("product.jpg")
if err != nil { panic(err) }
result.Save("product_cutout.png")

Cheapest background eraser API — pricing compared

PixelAPI sets its price at 2× below the cheapest publicly listed per-image rate among mainstream background eraser APIs. That constraint is built into how we run the pricing — not a marketing claim.

Pricing verified from each rival's public pricing page May 2026. For rivals whose pricing pages are JavaScript-rendered (and therefore not crawlable), we link directly rather than risk publishing a stale number.

What you get back

Every call to the background eraser API returns a transparent PNG with the subject isolated from its background. The alpha channel preserves fine details that trip up lesser tools:

Who uses the cheapest background eraser API

At $0.0025/image the economics work at every scale — from a solo Shopify seller with 200 SKUs to a marketplace with 2 million listings. Common customer profiles:

• Ecommerce operators — batch-process product catalogs for Amazon, Shopify, WooCommerce, BigCommerce with white or transparent backgrounds.
• Photography studios — automate post-processing on session delivery; integrate with Lightroom exports via folder-watch scripts.
• Marketing agencies — cut out client products for ads, social assets, and print collateral without manual retouching.
• Headshot photographers — deliver studio-look portraits with consistent backgrounds for LinkedIn and corporate directories.
• Real estate teams — isolate furniture, appliances, and staging items for virtual room-planning tools.
• SaaS builders — embed background removal as a one-click feature inside photo editors, design tools, and marketplaces without building the model yourself.

Comparison vs alternatives

Rate limits & error handling

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

# Python SDK handles 429 with automatic exponential backoff
from pixelapi import PixelAPI

client = PixelAPI(api_key="YOUR_API_KEY", max_retries=4)
result = client.remove_background(image="product.jpg")
# SDK retries on 429 — no boilerplate needed

Other error codes to handle:

• 400 Bad Request — invalid file format or file exceeds 20 MB. Check the detail field for the specific reason.
• 401 Unauthorized — API key is missing or invalid. Confirm the Authorization: Bearer YOUR_KEY header is present.
• 402 Payment Required — credit balance is zero. Top up credits from the dashboard.
• 429 Too Many Requests — rate limit hit. Back off and retry after the Retry-After value.

If a processing job fails (not a network error), credits are automatically refunded — you are never charged for a broken result.
