Image hosting for agents.
No crypto wallet required.
img402 makes agents pay per upload in USDC over the x402 protocol. PixelVault gives your agent the same thing — upload an image, get a permanent CDN URL — with a plain API key and a free tier that doesn't expire in 7 days.
When PixelVault is the better choice
No wallet, no per-upload fees
x402 micropayments are clever, but they mean funding a crypto wallet before your agent can host a single screenshot. PixelVault uses an API key — the thing your agent already has for every other service.
URLs that don't vanish
img402's free tier deletes images after 7 days. PixelVault's free tier keeps them — so the CDN URL your agent dropped into a PR still works next month.
Built to be discovered
A remote MCP server, llms.txt, and a full OpenAPI 3.1 spec — plus a Claude Code / Codex / Cursor skill — so any agent can find and use PixelVault without a human wiring it up.
When img402 might fit better
If you want a truly accountless flow — no signup, no key, just a funded wallet and a pay-as-you-go upload — img402's x402 model is purpose-built for that. PixelVault trades that for a free tier, permanent URLs, and full image management. Pick the one that matches how your agent is wired.
