Use a username and a password as your Weather API key to gain access to Meteomatics weather data. In this article, we will explain how to get a free Weather API key. Whether you are a seasoned developer or a novice looking to integrate weather data into your application, we have you covered.

What Is a Weather API Key

A weather API key is a unique identifier used by the majority of providers that allows developers to access a weather API and retrieve weather data from the provider's servers.

In other words, a weather API key can be seen as proof of entitlement to specific parts of a warehouse. Instead of letting users navigate the warehouse themselves, the API acts as a gatekeeper, allowing access only to those who can prove they are authorized to receive the requested items. Just like a delivery slip and ID, the API key is used to authenticate and authorize access to the desired data.

Most weather data providers work with a static key, but this is not generally considered secure as they do not expire, meaning if they are stolen they can be used indefinitely.

We have made things much easier and safer for you. Just keep reading to learn how to get a Weather API key from Meteomatics.

Get a Weather API Key From Meteomatics

At Meteomatics, we provide our users with login credentials to access our comprehensive weather data through our Weather API.

To further enhance the security of our users' data and reduce the risk of unauthorised access, we also offer a short-lived token generated through OAuth authentication. This token is valid for 3 hours and can be used to call the API without the need to enter credentials for each query.

By using this token, users reduce the risk of their credentials being stolen or compromised by unauthorized individuals. Additionally, if someone does manage to get hold of the token, it will only be valid for a short period of time, after which it will expire and no longer provide access to the API. This OAuth authentication system provides an additional layer of security for our users and ensures that their data remains safe and secure at all times.

When you sign up for one of our options to access the Weather API, you will receive a free Weather API key in the form of your Meteomatics login credentials.

These options include the Free Basic Weather API Account and the 14-days Free Trial of our Business package.

How to Obtain an OAuth Token for Extra Security

1. Go to this link https://login.meteomatics.com/api/v1/token

2. Insert your login credentials to receive a token directly on your browser. It will look like this:

{"access_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJ2IjoxLCJ1c2VyIjoiYWFva2kiLCJpc3MiOiJsb2dpbi5tZXRlb21hdGljcy5jb20iLCJleHAiOjE2ODAxMDM3MjIsInN1YiI6ImFjY2VzcyJ9.jJTSepDG4zdPsIHdPv6Skfm1HO0mmBKH9rOGz5rXJk0WS8_od3OVrq680wtWAORdA3psANwUfqNKMEc2pw1lFw","token_type":"bearer"}

3. Copy the entire token without the quotation marks, i.e., in the example above the token would be:

eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJ2IjoxLCJ1c2VyIjoiYWFva2kiLCJpc3MiOiJsb2dpbi5tZXRlb21hdGljcy5jb20iLCJleHAiOjE2ODAxMDM3MjIsInN1YiI6ImFjY2VzcyJ9.jJTSepDG4zdPsIHdPv6Skfm1HO0mmBKH9rOGz5rXJk0WS8_od3OVrq680wtWAORdA3psANwUfqNKMEc2pw1lFw

4. Make a query using the URL Creator.

5. Type ?access_token= followed by your token at the end of the URL. It should look like this:

https://api.meteomatics.com/2023-03-29T00:00:00Z/t_2m:C/52.520551,13.461804/html?access_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJ2IjoxLCJ1c2VyIjoiYWFva2kiLCJpc3MiOiJsb2dpbi5tZXRlb21hdGljcy5jb20iLCJleHAiOjE2ODAxMDM3MjIsInN1YiI6ImFjY2VzcyJ9.jJTSepDG4zdPsIHdPv6Skfm1HO0mmBKH9rOGz5rXJk0WS8_od3OVrq680wtWAORdA3psANwUfqNKMEc2pw1lFw
