How this service works
Daily OHLCV bars for a US equity: the last `days` sessions, 1 to 250, default 30. Daily only, no intraday. Built from the official consolidated end-of-day summary across all US exchanges and ATSs, so price, range and volume are market totals. If that dataset is unavailable for a read, the answer comes from a consolidation of three U.S. exchange venues instead and says so: coverage reads three-venue, venueVolume counts those venues only and volume is null.
Output
A flat array of bar objects each containing time, open, high, low, close, and volume fields for the requested symbol, interval, and range — suitable for direct use in charting libraries or quantitative backtests.
Example use cases
Example prompt
“Pull the daily OHLCV bars for NVDA over the past 6 months so I can chart them and run a backtest.”
Technical details
Endpoint
GEThttps://agent402.tools/api/stock-history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured OHLCV candlestick data for US stocks, ETFs, or indices at a specific granularity (from 1-minute to monthly) and a defined historical window. Prefer this over a live quote endpoint when you need multiple historical data points for charting, backtesting, or technical analysis. Note that intraday data is capped at ~60 days by the upstream provider.
Side effects
- Invalid or unknown ticker symbol returns an error or empty array
- Intraday intervals (1m–60m) requested for ranges beyond ~60 days return truncated or no data due to Yahoo Finance limits
- Missing required 'symbol' query parameter returns a validation error
- Unsupported interval or range value returns a 400 bad request
- Network or upstream Yahoo Finance outage may cause 5xx errors
