Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/YahooFinanceAgent/fetch_price_historyWhen to prefer
Use this endpoint when you need structured historical price data (OHLCV) for stocks or major cryptocurrencies, especially when you need candlestick granularity at hourly or daily resolution. Prefer this over general web search when you need clean, structured time-series price data rather than news or narrative content. Best suited for backtesting, charting, or quantitative analysis tasks involving major equities or top-30 large-cap crypto tokens.
Side effects
- Invalid or unsupported symbol returns an error or empty dataset
- Intraday (1h) data requested beyond 60-day limit returns an error or truncated data
- Unsupported interval (not 1h or 1d) causes a validation error
- Crypto symbol missing -USD suffix results in no data found
- Date range outside available history returns empty or partial results
- Network or upstream Yahoo Finance unavailability causes a timeout or 5xx error
