What it can do

  • Get Spot Price: Return the latest aggregated spot (or GC futures) price for one symbol. Price is a Decimal-formatted string; `is_stale` is true when aggregator detected source divergence or stale FX.
  • List Commodities: Return the full list of symbols served by this API. Use before get_spot_price / get_historical / get_metadata when you don't know which symbols are supported.
  • Get Metadata: Return provenance metadata for a symbol: aggregated sources, unit, methodology URL, staleness rules. Use for attribution and to document data lineage in downstream reports.

Server tool list (7)

Raw names from tools/list. Only developers need these.

get_spot_priceReturn the latest aggregated spot (or GC futures) price for one symbol. Price is a Decimal-formatted string; `is_stale` is true when aggregator detected source divergence or stale FX.
list_commoditiesReturn the full list of symbols served by this API. Use before get_spot_price / get_historical / get_metadata when you don't know which symbols are supported.
get_metadataReturn provenance metadata for a symbol: aggregated sources, unit, methodology URL, staleness rules. Use for attribution and to document data lineage in downstream reports.
get_historicalReturn daily OHLCV bar history for a symbol. History depth is set automatically by your API key's plan — do NOT pass a tier argument (there is none): Free + Basic see the last 30 days; Pro unlocks full history back to 2006 (XAU/USD). 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).
search_newsSearch recent commodity-market news from curated sources (FT Commodities and Mining.com at v1; more sources rolling out post-launch). Returns up to `limit` items ranked by source quality x recency (weight x exp(-hours_old / 48)). Use before answering 'what happened in gold this week' so you cite live headlines instead of training-data approximations.
search_docsSearch the goldprice.dev FAQ corpus via BM25. Returns top-K matching questions + answers with relevance scores. Use before answering how-to / billing / auth questions so you cite the canonical text instead of guessing from training data.
get_forward_viewReturns the multi-horizon futures settlement curve for a commodity (XAU, XAG, HG). Every populated horizon up to one year forward. Useful for bot builders and traders seeing the futures-implied path. See https://goldprice.dev/methodology#forward-view-layers for per-layer math.
