Server tool list (9)
Raw names from tools/list. Only developers need these.
| start_checkout | Open a direct billing URL for an explicitly selected eligible plan: a one-hour Stripe Checkout URL for Free accounts or the existing customer's Stripe billing portal. This always asks the human to confirm the same plan first; a cancellation creates nothing. |
| get_spot_price | Return the latest aggregated spot (or GC futures) price for one symbol. Price is a Decimal-formatted string. Latest USD spot price/bid/ask use nearest half-up rounding: XAU 2 decimal places, XAG 3, HG 4. `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. |
| get_carat | Return per-gram gold (XAU) prices by karat purity — 24k, 22k, 21k, 20k, 18k, 16k, 14k, 10k — in a requested currency (default USD; the same 31 currencies get_spot_price serves). Jewelry-grade pricing computed from live XAU spot + ECB FX. FREE on every tier — no plan gate. Values are Decimal-formatted strings, quantized to the currency's ISO 4217 minor unit (JPY → whole numbers, USD → 2dp). |
| get_historical | Return OHLCV bar history for a symbol at 1m, 5m, 15m, 30m, 1h, 2h, 4h, or 1d (default). Intraday intervals require Pro. History depth is set automatically by your API key's plan — do NOT pass a tier argument (there is none): Free sees the last 30 days; Physical sees the last year; Pro unlocks full history back to 1996 (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, XCU/USD); real for futures (GC, SI, HG) and ETFs (GLD). |
| search_docs | Search 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_view | Returns 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. |
| get_physical_price | Return the latest per-country physical dealer/retail gold prices — real quotes from dealers, mints, and bullion benchmarks, NOT spot-derived arithmetic — with nullable premium_over_spot_bps per quote (null when live reference inputs are unavailable). `country` is an ISO 3166-1 alpha-2 code (e.g. ID, IN, AE, JP). Requires the Physical tier or higher; static sample responses for evaluation are in the docs at https://goldprice.dev/docs/physical. |
