# get_historical

Return daily OHLCV bar history for a symbol.

Dates must be ISO 8601 (YYYY-MM-DD). Returns bars in date-descending order. volume is null for spot instruments (XAU/USD, XAG/USD); real for futures (GC, SI, HG) and ETFs (GLD).

## Why get_historical is rated Low

This is a pure data retrieval function that queries historical pricing information. It retrieves time-series data for gold, silver, copper commodities with no ability to modify data, execute code, or perform financial transactions. The tool is read-only with minimal blast radius if misused—an AI might retrieve unwanted historical data but cannot cause harm beyond information disclosure.

From the tool's own definition: "Tool returns historical OHLCV bar data; description states 'Return daily OHLCV bar history' with no modification, deletion, or execution capabilities. Parameters are read-only (symbol, dates in ISO 8601 format). No side effects or state changes."

## Use case

AI agents call get_historical to retrieve information from Goldprice Dev without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
