We built The World API data product with scale in mind.

It offers you 10k API requests per month, with the ability add 10k more API requests for only $20USD per month.

Your API requests are not linked to any set 'site' or location, and can be used in any manner that you choose.

With 10k API requests per month, you can achieve the goals of most applications.

Each World API request for forecasts provides you the latest forecast data, out to 7 days ahead.

Each World API request for live data, provides you the estimated actuals data for the past 7 days.

Each API endpoint is updating on our Rapid Update cycle, meaning new data is available every 5-15 minutes depending on your location.

This of course depends on your solution, but in all likelihood, it is probably less than you'd expect.

For applications where you need 'estimated actuals' of solar irradiance or PV power, you can use our live data. You may need only 1 API request per week, per location, as each live API request contains the past 7 days of data.

For forecasting applications, most use cases require a day-ahead forecast. Here, you would only need to make an API request for forecast data once per day, per location. This is because each API request will provide you with the forecast from now, through 7 days ahead.

Some applications may want to take advantage of our Rapid Update cycle capability, and get the latest live or forecast data with each data update cycle, which occurs every 5-15 minutes. This will significantly increase the total number of API requests you need. However, these use cases are much less common!

Another important consideration is relevant for applications where locations of interest are located close to one another. For example, a user may require day-ahead solar forecasts for several small scale PV systems which are located within 5-10km of one another. It is not necessary to make an individual API request for each of these systems, as they are likely to experience similar irradiance conditions.

Using this information, you can make a simple calculation based on the number of locations you'll need to retrieve data for, and how often you need to request new data.

Here is an example where the user needs 2 API requests per day for various scenarios with 100 to 10,000 locations ('sites' in the below image)

Here is an example where the user needs 1 API requests per day for various scenarios with 100 to 10,000 locations ('sites' in the below image)

In both of the above examples, the 'Total Price per Month' is increasing at $20USD per 10,000 API calls.
