Price data is the first thing a finance agent needs and one of the most fragmented: every vendor has its own symbols, intervals and limits, and the exchange feeds themselves are priced for institutions. Through AgentKey your agent pulls quotes, candles, option chains and market status the same way it pulls everything else — find_tools, describe_tool, execute_tool — with yfinance, Finnhub and AlphaVantage behind the scenes for global markets and Tushare for China and Hong Kong.

How to use it

Pass the request in plain language and let the router pick the tool:
Name the interval and the market in the request (“weekly”, “Hong Kong”, “options”) and the router ranks the right provider first. Always describe_tool before executing — symbol formats, interval names and per-call costs differ between providers.
Building with code? The same capability is available as fixed-contract Scenario Methods with automatic provider failover: finance.quote, finance.price.history, finance.symbol.search.

FAQ

It depends on the route. One provider serves real-time quotes for US stocks; another returns a real-time or delayed snapshot depending on the exchange. describe_tool states what each tool returns. Historical candles are the same on every route.
Most routes take the exchange-suffixed form, for example 0700.HK for Tencent in Hong Kong or 600519.SS for Kweichow Moutai in Shanghai, while plain AAPL works for US listings. One provider lists its symbols as exchange ticker plus exchange code. When unsure, resolve the name with the ticker search first and pass the symbol it returns.
Daily, weekly and monthly series reach back 20+ years on the time-series routes. Intraday bars cover shorter windows; describe_tool documents the range each interval supports.
