Where does your gold price come from?

XAU is a mid-market reference rate: the midpoint between the live bid and ask, taken from real-time market data for the global over-the-counter spot gold market, sourced from official banks and exchanges. The market is centred on London, where banks and dealers trade physical gold around the clock, and XAU is refreshed every second.

Is this the LBMA Gold Price?

No. The LBMA Gold Price is a benchmark set by auction twice a day, at 10:30 and 15:00 London time, and administered by ICE Benchmark Administration. XAU is the live spot price from the same over-the-counter market, so it moves every second, including between those auctions.

Is this the COMEX gold price?

No. COMEX gold is a futures contract in New York and usually trades slightly above spot because of time to delivery. XAU is a spot price.

Live gold rates

Returns the latest spot rate for gold (XAU): the mid-market price from the global over-the-counter spot market, including bid and ask prices.

Endpoint

GEThttps://api.commoditypriceapi.com/v3/rates/latest/xau

Every current plan receives real-time rates. Basic plan users receive rates in USD; the quote parameter is not available on that plan. Standard, Advanced and Enterprise users can request any supported quote currency. On the legacy Lite plan rates are in USD and may be delayed by up to 10 minutes.

Authentication

X-API-Keyheader · stringrequired

Your unique API key, passed as a request header. Find it in your dashboard.

Query parameters

quotestringoptionalStandard & above

The target currency to convert the rate into. If omitted, the commodity's native quote currency (USD) is used. Basic and legacy Lite plan users cannot use this parameter — it is silently ignored.

includestringoptional

The unit to express the rate in. Additional unit-specific fields are appended to the rate object alongside the base troy ounce rate. Accepted values:

gram— appends a gram field with the per-gram rate (1 troy oz ÷ 31.1035)
tola— appends a tola field with the per-tola rate (1 troy oz ÷ 2.66667)
carat— appends a carats object with per-gram rates for 24k, 22k, 21k, 20k, 18k, 16k, 14k, 12k, 10k, 9k, and 8k purity

The base rate, bid, and ask fields are always returned in troy ounce regardless of this parameter.

metadatabooleanoptional

Whether to include the metadata object in the response. Defaults to true. Pass false to receive only the rate and keep the payload minimal. Any other value is treated as the default.

Response fields

successboolean

Always true for 200 responses. Indicates the request was processed successfully.

timestampnumber

Unix timestamp (seconds) of when the rate was generated on the server.

rates.XAUobject

Rate data for XAU. Includes rate (mid-market price per troy ounce), bid (highest buy price), and ask (lowest sell price). Additional fields — gram, tola, or carats — are present only when the include parameter is passed.

metadata.XAUobject

Context for the returned rate — the unit it's expressed in (T.oz) and the quote currency (e.g. USD, or whichever currency was requested). Omitted when the request sets metadata=false.
