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.

Could you build this?
Partial The marketplace UI and OpenAI/Anthropic-compatible proxy are vibe-codeable, but payouts in USDC and bank transfers bring money-transmission, KYC/AML, and fraud problems. Reselling API capacity may also conflict with provider terms of service.
What it would actually take: Build an API gateway that proxies and meters requests to upstream providers, with per-key routing, token accounting, and rate limiting. Add a marketplace with listing, escrow, and settlement, and integrate a payments provider such as Stripe for bank payouts and a stablecoin processor for USDC. Real use requires a fintech or compliance lawyer for money-transmission and ToS questions, plus someone who can run high-throughput, low-latency infrastructure reliably.
