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.
