Notes

  • US equities only — NYSE and NASDAQ listed stocks.
  • Daily interval only — minute-level data is not available.
  • Closed trading days only — the current trading day is not included until market close.
  • No real-time quotes — use this endpoint for historical data, not latest prices.
  • First request latency — the first query for a given ticker + range may be slower as data is fetched from yfinance and cached. Subsequent queries for the same range return instantly.
  • Data source — powered by yfinance (unofficial); approximately 98% success rate.
