Commercial use license, support and dedicated API capacity

Free for non-commercial

Open-Meteo APIs are free for non-commercial use. We do not restrict access, but ask for fair use and attribution.

Kindly ensure that your daily requests remain below 10,000. Please note that we retain the right to block applications and IP addresses that misuse our service. For additional information, please refer to the terms and conditions.

Commercial Use License

Commercial clients enjoy the advantages of dedicated API servers and personalized support. If you have any inquiries or require assistance, please feel free to reach out to us at

During the evaluation, prototyping, and development stages, we encourage you to utilize the free tier. However, for your production system, we will provide you with an API key to ensure that your application reliably receives weather data.

Large API Call Volume

The API price includes millions of API calls, and you will not be billed for each individual API call. We suggest updating the weather forecast API every hour to achieve optimal accuracy.

If you anticipate a higher volume of API calls, you have the option to adjust the quantity of the API professional plan, doubling or even tripling the number of monthly API calls.

If you anticipate billions or more API calls, we recommend self-hosting the API. Feel free to reach out to us, and we will provide assistance and support for your self-hosting needs!

Excellent Uptime, Low Latency

Our API is built with top-tier servers and redundant data centers to ensure exceptional availability, reaching 99.9% uptime. You can monitor the real-time statistics at:

To provide low latency and increased redundancy, our servers are strategically located in Europe and North America. We are also planning to introduce additional servers in Asia soon.

Flexible Payment Options

We offer a range of payment methods to suit your preferences. You can make payments using credit cards, Apple Pay, Google Pay, SOFORT, or SEPA. Once you complete the purchase, you will receive a PDF invoice, and you have the freedom to cancel your subscription at any time. All payment transactions and subscriptions are securely processed through Stripe, and you can conveniently manage your subscription details in the customer portal.

Transparent Pricing, Flexible Cancellation

Our API subscription comes with a predictable cost, ensuring that you won't encounter any unexpected overcharges. The subscription price remains fixed throughout your usage. If you require additional API calls, you have the freedom to upgrade your API subscription at any time through the customer portal. We strive to provide you with complete control and flexibility over your subscription.

Frequently Asked Questions

How does the subscription process work?

To subscribe, you can sign up using a credit card by clicking on the subscription button above. Once you complete the subscription, you will immediately receive an API key and a PDF invoice. This API key allows you to access the dedicated API instances for customers. If you ever wish to cancel your subscription, you can do so at any time through the customer portal.

What happens if I exceed my monthly call volume?

If you approach 80%, 90%, or 100% of your monthly call volume, you will receive email notifications to keep you informed. However, due to the ample number of API calls provided, it is unlikely that you will reach this limit.

What sets apart the free API from the customer API?

The free API is accessible to everyone for non-commercial purposes and does not come with any service guarantees. On the other hand, the customer API is specifically designed for commercial use, offering dedicated API server instances to ensure sufficient resources and reliable API performance.

To differentiate between the two, the customer API uses distinct domains such as and includes API keys in the URL, denoted as &apikey=abc123. Apart from these variations, the syntax of the customer API remains identical to the free API.

Using the Standard API Plan can I use historical, climate and ensemble data?

Access to historical, climate, and ensemble data is limited to the Professional API Plan. If you are interested in utilizing this data, you can easily upgrade your subscription by visiting the customer portal

How is one API call defined?

Typically, one API call corresponds to one HTTP API request. However, if you select 200 weather variables simultaneously and make extensive use of the API, the number of API calls can increase. Therefore, API queries that involve more than 10 weather variables or more than 7 days of data are considered more than just one API call.

To calculate the number of API calls accurately, fractional counts are used. For example, 15 weather variables count as 1.5 API calls, while 4 weeks of weather data count as 3.0 API calls.

This distinction is crucial for developing future features such as APIs for multiple locations simultaneously.
