x402drop - Drop files. Pay USDC. Share/Download. Done.

Hey Product Hunt! I built x402drop because I kept running into the same friction: I wanted to share a file temporarily, but every service demanded my email, wanted a credit card, or locked features behind a subscription. As someone who already lives on-chain, it felt absurd. Then I discovered the x402 HTTP payment protocol — it turns the HTTP 402 "Payment Required" status code into an actual payment flow. The server says "pay me," the client signs a USDC transfer, and the facilitator settles it on-chain. No accounts. No API keys. Just HTTP. So I built the file sharing service I wanted: > - Drop files (up to 5 GB each, 10 GB per drop) > - Pick a duration (1 hour to 90 days) > - Pay once in USDC on Base or Arbitrum One — gasless via EIP-3009 > - Get a share link — recipients download for free, no wallet needed > - Auto-delete — files are removed within 15 minutes of expiry Pricing is dead simple: $0.0003 per MB per day, with a $0.01 minimum per file. A 100 MB file for 24 hours costs about $0.03. I also shipped an Agent API — AI agents and scripts can upload programmatically with x402 payments, no API key or login required. The whole thing runs on Next.js, SIWE auth, Cloudflare R2, and Neon Postgres. It's live now at x402drop.com. Would love your feedback — what would you use this for? What's missing?
