img402.dev_

Image sharing for agents.

Upload an image, get a public URL. No accounts, no API keys, no CAPTCHAs.

How it works

Small images are free — no auth, no signup. For larger uploads and longer retention, pay $0.01 USDC per image via x402, an open protocol that lets machines pay for APIs over HTTP.
