About

402 Index is a protocol-agnostic directory of paid APIs for AI agents. Provides searchable access to over 15,000 endpoints across L402 (Lightning Bitcoin micropayments), x402 (USDC stablecoin payments), and MPP (Stripe/Tempo fiat payments). Each endpoint includes hourly health checks, latency measurements, and reliability scoring. Enables agents to discover and evaluate paid APIs across multiple payment protocols before committing funds.
