30+ Weather Models
Weather models from ECMWF, DWD, NOAA, MÊtÊo-France, JMA, KMA, KNMI, DMI, MeteoSwiss, UK Met Office, BOM, CMA, GeoSphere Austria, and more. The best_match option automatically selects the highest-resolution model for any coordinates.
Resolution ranges from 1â2 km (regional mesoscale) to 9â11 km (global). All output is normalised to hourly resolution.
Commercial Use Licence
A subscription grants a commercial use licence and an API key for the dedicated customer endpoint at customer-api.open-meteo.com. The API syntax is identical to the free tier â only the domain and key parameter differ.
Use the free tier for evaluation and prototyping. For custom volume requirements or enterprise contracts, contact info@open-meteo.com.
High-Volume Usage
Plans are priced on a monthly call budget, not per individual request. Standard: 1M calls/month. Professional: 5M calls/month. Enterprise: 50M+ calls/month.
For workloads in the billions, self-hosting the open-source server is the practical path. Contact us for guidance on deployment and infrastructure sizing.
Uptime and Latency
Paid plans run on reserved server instances with a 99.9% uptime target. Live status and incident history are at status.open-meteo.com.
Servers are located in Europe and North America for low-latency access across both regions.
Payment Options
Payments via credit card, Apple Pay, Google Pay, SOFORT, or SEPA â processed through Stripe. A PDF invoice is issued on each billing cycle. Subscription details and payment method are managed in the customer portal.
Predictable Pricing
Fixed monthly price â no per-call overages or surprise charges. Upgrade or downgrade at any time via the customer portal. Cancellation takes effect at the end of the current billing period.

Frequently Asked Questions
How does the subscription process work?
Click a plan above to subscribe via Stripe. After checkout, an API key and PDF invoice are issued immediately. The key grants access to customer-api.open-meteo.com. Cancel, upgrade, or update payment details at any time in the customer portal.
What happens if I exceed my monthly call volume?
Email alerts are sent at 80%, 90%, and 100% of your monthly budget. A usage dashboard is in development â until it is live, no hard cutoffs are enforced.
What sets apart the free API from the customer API?
The free API is for non-commercial use, rate-limited to 10,000 calls/day, and carries no uptime guarantee. The customer API runs on dedicated servers, has no daily rate limit, and includes a commercial use licence.
The customer endpoint is customer-api.open-meteo.com; requests include &apikey=abc123. All parameters and response formats are otherwise identical to the free API.
Using the Standard API Plan can I use historical, climate and ensemble data?
Historical, climate, ensemble, and satellite radiation APIs require the Professional API Plan or higher. Upgrade via 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. Requests for data covering more than 10 weather variables or extending over a period of more than 2 weeks for a single location are considered multiple API calls.
To calculate the number of API calls accurately, fractional counts are used. For example, a request for 2 weeks of data with 15 weather variables will be calculated as 1.5 API calls, while 4 weeks of data equals 3.0 API calls.
This distinction is crucial for developing future features such as APIs for multiple locations simultaneously.
Is it necessary to provide attribution to Open-Meteo?
Open-Meteo relies on open data that is licenced under Attribution 4.0 International (CC BY 4.0). This licence mandates giving appropriate credit and indicating any modifications made to the data.

Unlock the Power of Open-Source Weather Data!
Subscriptions fund the infrastructure, data ingestion pipelines, and ongoing development behind the API. The server code is open-source under AGPLv3; the weather data is CC BY 4.0.
Commercial plans add a dedicated endpoint, an API key, and a 99.9% uptime target. For custom volume requirements or enterprise contracts, contact info@open-meteo.com.
