Alternative to img402 # 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. PixelVault img402 Payment to upload None — API key $0.01 USDC per upload (x402) Crypto wallet needed No Yes (Base / Solana) Free tier retention Permanent 7 days Free tier file size 5 MB 1 MB API REST with OpenAPI 3.1 Upload endpoint Agent discovery MCP server + llms.txt + OpenAPI SKILL.md Image management List, get, delete via API Upload only ## 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](/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. ## Try PixelVault free 200 MB storage, 500 uploads/month, zero egress fees. No credit card, no wallet. [Get started](/docs)
