2025 API LTA release notes

Release date	Released features
28.5.2025	API upgrade The API service accessible at URLs starting with https://solargis.info/ws/rest/datadelivery/request (Solargis API LTA) has been upgraded to provide enhanced transparency and usability. New response headers for enhanced transparency: Custom response headers are now included in every API response (where applicable) to provide real-time visibility into API usage and limits: solargis-usage-total and solargis-limit-total: Show the total number of calls made and the allowed limit for the entire subscription period. solargis-usage-unique-locations and solargis-limit-unique-locations: Monitor the number of unique locations accessed, valid for the entire subscription period. solargis-request-id: Assigns a unique ID to every API transaction for easier tracking and support. Users can now check their API consumption after each call for improved transparency and self-management. Usage API discontinued: The Usage API previously available at https://solargis.info/ws/usage/ has been discontinued. Usage information is now provided directly in each HTTP response header. New HTTP response codes: API error handling has been improved with updated response codes: 429 Too Many Requests is now returned when rate limits are exceeded (previously 403 Forbidden). 401 Unauthorized is now returned for invalid API keys or tokens (previously 403 Forbidden). More helpful error messages: Error messages have been improved for greater clarity and easier troubleshooting. Demo access updates: The demo access password for the pvplanner endpoint (Solargis API LTA) is now 'demo_pvplanner'. The password for the demo subscription to the datadelivery endpoint (Monitor API, Forecast API) remains 'demo'. Cleanup of Solargis API LTA response: The LTA API response now includes only those properties from the PV system element that directly affect simulation results. Irrelevant properties have been removed from the XML response for greater clarity and efficiency. Untouched API interface and data format: This upgrade does not change the API interface or data format (XML). Data values remain unchanged, ensuring compatibility with existing integrations.
