How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a URL to the newly generated image (hosted on api.delx.ai), the sale price charged in USDC (0.003), and a boolean indicating whether the output image contains transparency. The image URL is publicly accessible and points directly to the background-replaced PNG.
Example use cases
E-commerce product photo cleanup
“Take this JPEG of my sneaker product shot and replace the background with a clean white studio fill (#FFFFFF) so it looks professional for my online store listing — here's the image in base64.”
Consistent brand photo backgrounds
“I have a base64-encoded PNG of a team headshot and I want to replace the background with our brand color #1A2B3C so all our team photos look uniform.”
Quick mockup background swap
“Here's a base64-encoded WebP image of my prototype gadget — can you replace the background with studio gray so I can use it in a presentation mockup?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/replace-background?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, no-signup, pay-per-result background replacement that accepts a raw base64 image and returns a hosted URL immediately. It is ideal for agentic workflows that require verifiable USDC-based micropayments (x402 on Base or Solana) and exact per-call pricing with no subscription or API key management. Prefer it over subscription-based image editing APIs when you want deterministic cost per operation and when you only need a solid studio fill rather than AI-generated scene backgrounds.
Side effects
- Image too large — base64 input exceeds 349,550 characters (256 KiB decoded) returns a validation error
- Invalid base64 encoding or unsupported image format (must be PNG, JPEG, or WebP) causes a 400-level error
- Invalid hex color format for the fill parameter causes a validation error
- Payment failure via x402 protocol (insufficient USDC balance) blocks the request
- Network or processing timeout if the background replacement model is slow or unavailable
