How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing a publicly accessible URL pointing to the colorized image (image_url) hosted on Delx's servers, and the confirmed sale price in USDC (sale_price_usdc, typically 0.01). The colorized image is a color-rendered version of the submitted grayscale or black-and-white photo.
Example use cases
Restore old family portraits
“I have a scanned grayscale photo of my grandparents from the 1940s encoded in base64 — can you colorize it so it looks like a realistic color photograph?”
Colorize historical archive images
“I'm working on a history project and need to colorize these black-and-white archival images. Here's one as a base64 JPEG — please add realistic color to it.”
Enhance monochrome product mockups
“I've got a grayscale mockup image in base64 format that I'd like converted into a color version — can you colorize it for me?”
