Metals-API API

Powered by 10+ exchange rate data sources for precious metals, the Metals-API API is capable of delivering real-time precious metals rate data. The API comes with multiple endpoints, each serving a different use case. Endpoint functionalities include getting the latest exchange rate data for all or a specific set of currencies, converting amounts from one currency to another, retrieving Time-Series data for one or multiple currencies and querying the API for daily fluctuation data.

Throughout this documentation you will learn about API structure, methods, potential errors and code examples. In case any question was left unanswered, please make sure to contact us and our team will be happy to help out.

Getting Started

Definitions

Definition	Description
API Key	A unique key assigned to each API account used to authenticate with the API.
Symbol	Refers to the three-letter currency code or metal code of a given currency.
Base Currency	The currency to which exchange rates are relative to. (If 1 USD = X EUR, USD is the base currency)
Target Currency	The currency an amount is converted to. (If 1 USD = X EUR, EUR is the target currency)
Base URL	Refers to URL which all API request endpoints and URLs are based on.

API Key

Your API Key is the unique key that is passed into the API base URL's access_key parameter in order to authenticate with the Metals-API API.

Base URL:

https://metals-api.com/api/

Append your API Key: Here is how to authenticate with the Metals-API API:

https://metals-api.com/api/latest
? access_key = API_KEY

API Response

Exchange rates delivered by the Metals-API API are by default relative to USD. All data is returned in standard JSON format and can be parsed easily using any programming language.

When fetching metal rates with USD selected as the base currency (utilizing the 'base' parameter, defaulting to USD if not specified), it is necessary to apply 1/value to the API response.

For instance, to ascertain the gold rate in USD from the API response value, execute 1/0.0004831705, yielding 2069.6627795 USD.

Furthermore, when USD serves as the base, the API response will include the USD Price without requiring additional conversion. This can be identified, for example, as USDXAU. (ONLY APPLIES FOR LATEST ENDPOINT).

Additionally, it's important to note that if you opt for a different base currency, such as EUR, the 1/value division is not necessary. The price is already converted.

[...]
}
}

As illustrated above, the API's response - when queried for real-time exchange rates - always contains a timestamp object containing a standard UNIX time stamp indicating the time the given exchange rate data was collected, a base object containing the three-letter currency code or metal code of the base currency, a date object containing the date the given exchange rate data was collected, and a rates object containing the actual exchange rate data.

Further below, in the Endpoints section, the API response structure will be discussed in detail.

Available Endpoints

SSL Connection

All paid subscription plans available on Metals-API come with 256-bit SSL encryption. To connect to the API via SSL, simply use the https protocol instead of standard http.

JSONP Callbacks

The Metals-API API comes with support for JSONP Callbacks. This feature enables you to specify a function name, pass it into the API's callback GET parameter and cause the API to return your requested API response wrapped inside that function.

Example Call:

https://metals-api.com/api/latest
? access_key = API_KEY
& callback = MY_FUNCTION

In the example call above we are requesting the API to use the callback name MY_FUNCTION.

Example Response: Your API response will be wrapped inside your preferred callback function.

({
"success": true,
"timestamp": 1519296206,
"base": "EUR",
"date": "2018-09-10",
"rates": {
"AUD": 1.566015,
"CAD": 1.560132,
"CHF": 1.154727,

"USD": 1.23396,
[...]
}
})

Access-Control / CORS

Metals-API also supports Cross-Origin Resource Sharing (CORS) and Access-Control Headers. This will enable you to use the Metals-API API via Cross-Origin HTTP Requests.

Learn more about CORS »

HTTP ETags

HTTP ETags are a way of reducing the load on your back-end by requesting new Metals-API data only if rates have changed since the last API response.

What are ETags?

An ETag is a part of the HTTP protocol and one of the several mechanisms used for cache validation. The ETag is an identifier assigned to a data resource in a server, and if that resource is ever updated at the server, the ETag is changed.

Whenever a resource is requested (via its URL), the data and ETag are retrieved and stored in the Web cache, and the ETag is sent along with subsequent requests. If the ETag at the server has not changed, a "Not Modified" message is returned, and the cached data is used. (Definition by pcmag.com)

ETags - Quickstart Guide

Step 1

Your initial request to the Metals-API API will create an ETag object containing a unique ETag key and a Date object containing the exact date and time at which the data was last modified. This data must be cached along with the entire API response in order for ETags to work.

ETag: "202567a75aef2e66a3ebf2366bff048f"  
Date: Mon, 12 Apr 2018 11:30:01 GMT

Step 2

Once you make another API request, make sure to include the If-None-Match HTTP header abd set ut to your previously generated ETag value. Moreover, you will need to add the If-Modified-Since HTTP header to your API request containing the date and time data from your last request.

If-None-Match: "1872ade88f3013edeb33decd74a4f947"  
If-Modified-Since: Fri, 10 Apr 2015 12:10:04 GMT

Step 3

Depending on whether or not your result set has updated since your last API request, the API will return either:

the results from your initial API request along with a 304 – Not Modified HTTP header indicating that no change has occured. In this case, the size of the API response will be as small as 0.2kb;
or new results with an entirely new set of ETag and Date objects indicating that new data has been accessed. In this case, the size of your API response will be normal.

Potential Errors

Whenever a requested resource is not available or an API call fails for another reason, a JSON error is returned. Errors always come with an error code and a description.

Example Error: The following error is returned if your monthly API request volume has been exceeded.

{
"success": false,
"error": {
"code": 104,
"info": "Your monthly API request volume has been reached. Please upgrade your plan."    
}
}

Specify Symbols

To reduce bandwidth you can limit the number of output currencies to a specific set of your choice on most API endpoints. To do so, simply append the Metals-API API's symbols parameter to your API request and set it to one or more comma-separated currency codes or metal codes.

Example:

https://metals-api.com/api/latest
? access_key = API_KEY
& symbols = XAU,XAG,XPD

The API's response for the request above will be limited to the currencies USD, CAD and JPY.

Changing base currency

Provided changing base currency is supported on your subscription plan, you can change the currency to which your output currency rates are relative to by appending the base parameter to your API request URL and setting it to the three-letter code of your preferred base currency.

Example:

https://metals-api.com/api/latest
? access_key = API_KEY
& base = USD

Please note: The default base currency is USD. You can use any currency as base currency. If you need additional base currencies please contact us

Convert Endpoint

The Metals-API API comes with a separate currency conversion endpoint, which can be used to convert any amount from one currency to another. In order to convert currencies, please use the API's convert endpoint, append the from and to parameters and set them to your preferred base and target currency codes or metal codes.

It is also possible to convert currencies using historical exchange rate data. To do this, please also use the API's date parameter and set it to your preferred date. (format YYYY-MM-DD)

API Request:

https://metals-api.com/api/convert

Time-Series Endpoint

The Metals-API timeseries endpoint allows you to query the API for daily historical rates between two dates of your choice. (The date limits per API request depend on the acquired plan).

This endpoint has a limitation depending on the acquired plan, allowing only one symbol per request. If you need to query more than 30 days or more than one symbol, you should send another API call.

For LME symbols, the prices provided in this endpoint correspond to the first known price of the previous day (not the requested day). For example, a request for 2024-11-13 will return the price from 2024-11-12.

For LBMA symbols, there is a two-day delay. For example, a request for 2024-08-22 will return the closing price for the 20th.

For other symbols, the prices correspond to the first known price of the requested day.

You cannot use the current date for the "end_date" parameter. We recommend using a day prior to the current date to get a successful response. To get the latest price, you will need to use the latest endpoint.

We also offer specific historical endpoints for LBMA and LME, where older data is available.
