2025 Forecast & Monitor release notes

Release date	Released features
28.5.2025	Solargis Monitor API & Solargis Forecast API API upgrade: The API services accessible at URLs starting with https://solargis.info/ws/rest/datadelivery/request (Solargis Monitor API and Solargis Forecast API) have been upgraded to improve performance and transparency. Performance enhancements: The API backend has been upgraded to a high-performance, scalable framework for rate limit evaluation to reduce latency during API calls. Some users should experience faster response times and improved reliability. 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-month and solargis-limit-month: Track monthly API usage and limits, refreshing every calendar month (UTC). solargis-usage-day and solargis-limit-day: Track daily API usage and limits, refreshing at UTC midnight. 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 useful error messages: Error messages have been improved for greater clarity and easier troubleshooting. 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.
