Technology
WS API request parameters, represented as XML elements and attributes, are formally described by XML Schema Definition documents (XSD). We provide two endpoint variants for XML file validation:
- SOAP
- REST
The data period in one request is currently limited to a maximum of 31 days regardless of time resolution—the same applies for hourly or 15-minute time steps.
Terms
Price is specified individually based on your requirements. It reflects:
- Requested type and parameters (PVOUT, GHI, GTI, DNI, TEMP, etc.)
- Number of requests
Access to API is based on a one-year subscription. Authentication is based on an API key registered with the customer.
