CheapestInference

CheapestInference is unlimited LLM inference at a flat monthly price — no token caps, no per-token billing. Subscribe to a pool of frontier open-source models and use them through an OpenAI-compatible API (Anthropic-compatible endpoint included — works with Claude Code, Cursor, and any OpenAI SDK). This MCP server is the commercial front door: AI agents and humans can browse live pools and pricing, get a USDC quote, pay on Base L2, and receive an API key — end to end, no browser and no human needed. Card checkout links available too, and keyless pay-per-request is supported via the x402 protocol.
