GoldAPI Precious Metals Quotes

get_history and get_kline both return historical candle data and are the only pair that could be confused; the descriptions differentiate them by granularity (hourly vs daily), cost model (paid vs free), and range semantics (92-day window vs recent N days). get_realtime and list_varieties are clearly distinct from each other and from the history tools.

All names follow a clean snake_case verb_noun pattern (get_history, get_kline, get_realtime, list_varieties), with 'get' for data retrieval and 'list' for enumeration used consistently and meaningfully. No style mixing or vague verbs.

Four tools is tightly scoped to a market-data quote API: enumerate instruments, fetch realtime, fetch recent daily candles, fetch historical hourly candles. Each tool has a distinct role and nothing feels padded or missing at the structural level.

The surface covers the core lifecycle of a quote service: discover goldIds, then pull realtime, short-term daily, and longer historical series. Minor gaps exist (no currency/premium conversion or cross-ratio helper, and no explicit batch historical/kline call), but the listed order in descriptions lets an agent work around them.
