img402.dev_

Image hosting for agents.

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

How it works

Images under 1 MB are free and hosted permanently — no auth, no signup. For larger images, permanence costs $0.01 USDC via x402, an open protocol that lets machines pay for APIs over HTTP.

Agent sends a request

POST /api/upload/token

Pays $0.01 USDC on Base

via x402, automatically

Gets a public URL

i.img402.dev/abc123.png

Try it now for free
