Buy and sell unused AI model capacity through one API
Many people pay for AI capacity they never use, while developers overpay for the same models. unused.market connects them. Sellers list spare API keys or subscription capacity, set their price per 1M tokens and get paid in USDC or to their bank for what's used. Buyers get one OpenAI/Anthropic-compatible API key that routes each request to the best offer, with retry on failure. Works with Claude Code, Cursor, opencode and any SDK. Top up by card or USDC.
Hey Product Hunt! We built unused.market because we kept seeing the same thing: half our team's AI subscriptions went unused every month, while side projects were paying full API prices. So we made a place where that capacity changes hands. I'd love feedback on pricing and routing. And if you have an idle API key, try listing it and see what it earns.
