Is a stock exchange open right now? Pass exchange (default US); returns whether trading is open, the current session (pre-market, regular, post-market, or closed), whether today is a market holiday, the exchange timezone, and the server timestamp. Use it to gate time-sensitive logic to market hours. Data by Finnhub.
/api/markets/statusPAYMENT-SIGNATURE.The status API is a pay-per-call markets endpoint built for AI agents and autonomous software. Is a stock exchange open right now?
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 status data source for an agent tool-use loop, an MCP host, or a backend that needs markets data on demand without onboarding to yet another vendor portal.
