Frequently Asked Questions

Yes. The real-time price endpoint is free with unlimited requests. The price history and OHLC endpoints are also free for up to 10 requests per hour, shared between the two. If you need more than that, the Premium plan gives you unlimited access.

There's no catch. The service is heavily optimized: it's built with low-level languages and high performance databases, and live prices are kept in memory so responses are almost instant. Because each request costs so little to serve, we can offer generous free limits and keep the Premium plan cheap.

Yes. Gold, silver, platinum and palladium prices are per troy ounce (about 31.1 grams), the standard unit for precious metals. A troy ounce is slightly heavier than a regular ounce, so convert using 31.1035 grams, not 28.35.

Yes. The API returns the spot price, which is the current market price for immediate delivery. Dealers usually charge a premium on top of spot when selling coins and bars.

Not for real-time prices. The /price and /symbols endpoints need no key or sign up. The /history and /ohlc endpoints need an API key, sent in the x-api-key header.

Create a free account, then open the API Keys page in your dashboard to generate a key.

On the free plan, the history and OHLC endpoints share a limit of 10 requests per hour, so you could make 5 requests to each before being throttled. There is no rate limit on real-time prices, however, spam will be dealt with on a case-by-case basis. Spam is usually considered sending multiple requests per second to the same exact endpoint. Prices only change every 30 seconds, so cache each response for 30 seconds. IPs that spam the API may be banned.

Live prices are updated every 30 seconds. Every /price response includes a cache-control header with the number of seconds until the next update, so you know exactly how long to cache it.

Everything is in UTC, both in the API and on this website. Convert to your local timezone in your own code if you need to.

It's the time, in UTC, that we last fetched the price from our data source. It tells you how fresh the price is. If your app relies on up-to-date prices, it's good practice to check updatedAt before using a price, and handle it if the price is older than you'd expect.

Gold (XAU), Silver (XAG), Platinum (XPT), Palladium (XPD), Copper (HG), Bitcoin (BTC) and Ethereum (ETH).

Yes. Add the currency code to the end of the URL, for example /price/XAU/EUR. Supported currencies are USD, EUR, GBP, JPY, CAD, AUD, CHF, CNY, HKD, SGD, SEK, NOK, DKK, NZD, MXN, INR, BRL, ZAR and KRW.

Yes. CORS is enabled, so you can call the real-time price API straight from the browser. Keep API keys on your server though, since anything in frontend code is visible to visitors.

Yes. Commercial use is always permitted, including in web apps, mobile apps, and websites you build for clients. Attribution of this service is not required but it's appreciated.

Prices come from multiple data providers. If one goes down, the API falls back to the next source. We spot check and cross reference every data source, both historical and new, against others to make sure the data is good. We work hard to keep the data accurate, but we can't guarantee it, so please verify prices before making financial decisions with them.
