/api/stocks/metricsPAYMENT-SIGNATURE.The metrics API is a pay-per-call stocks endpoint built for AI agents and autonomous software. Key fundamental metrics and 52-week price statistics for a US-listed company.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in metrics data source for an agent tool-use loop, an MCP host, or a backend that needs stocks data on demand without onboarding to yet another vendor portal.
