How this service works

Edit an image with a prompt over x402 - OpenAI images.edit wire (reference images and a prompt in, inline base64 out) at $0.02 per picture. Send one to 4 PNG or JPEG reference images (256 px a side or more, up to 6 MB each) as base64 or data: URLs in JSON, or one as a multipart "image" file; the output is one JPEG of about one megapixel that follows the first reference's aspect ratio. Served by FLUX 3 Image Klein in about 10 seconds. No mask: describe the change in the prompt.

Output

A single JPEG image (~1 megapixel) returned inline as base64, preserving the aspect ratio of the first reference image, reflecting the edits described in the prompt. Typical response time is around 10 seconds.

Example use cases

Product photo background swap

“Here's my product image as a base64 PNG — can you edit it so the background looks like a sleek white studio with soft shadows? Keep the product itself unchanged.”

Artistic style transformation

“I have a portrait photo — can you re-render it in an oil painting style, keeping the person's likeness but making it look like a classical artwork?”

Scene element modification

“Edit this photo of my living room to remove the clutter on the coffee table and make it look clean and minimalist — here's the image encoded in base64.”

Endpoint

POSThttps://agent402.tools/v1/images/edits?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need to edit or modify an existing image using only a text prompt (no mask required), and want OpenAI images.edit API compatibility. It is ideal for agents already using the OpenAI image editing interface, or when you want low-cost ($0.02/call) FLUX-powered image editing with a simple base64 in/out interface. Prefer this over text-to-image generation endpoints when you have a reference image to start from.
