- [Site Climate - Climate Comparison by Coordinates](https://www.zero.xyz/c/site-climate-climate-comparison-by-coordinates-061a8f6a/llms.txt): $0.05/call via x402. Compare climate metrics side by side for two geographic locations, including temperature, rainfall, sunshine, wind, humidity, and Köppen classification.
- [Site Climate Rainfall Pattern](https://www.zero.xyz/c/site-climate-rainfall-pattern-fb2b7603/llms.txt): $0.02/call via x402. Returns monthly rainfall totals, wettest/driest months, and the Walsh-Lawler seasonality index for any geographic coordinates.
- [Site Climate Day Length & Solar Times](https://www.zero.xyz/c/site-climate-day-length-solar-times-7ebaa31f/llms.txt): $0.02/call via x402. Returns day length, sunrise, sunset, and solar noon times (UTC) for a given latitude, longitude, and date, including handling of polar day and polar night conditions.
- [Site Climate – Solar Resource (Monthly Sunlight & PV Yield)](https://www.zero.xyz/c/site-climate-solar-resource-monthly-sunlight-pv-yield-a45a3ec2/llms.txt): $0.02/call via x402. Returns monthly peak sun hours, solar resource class, and optional PV energy yield estimate for any latitude/longitude coordinate.
- [Site Climate Daily Weather History](https://www.zero.xyz/c/site-climate-daily-weather-history-b3080af7/llms.txt): $0.05/call via x402. Returns day-by-day historical weather data (temperature, rain, wind, sunlight) for any coordinates over a date range up to one year, plus summary statistics.
- [Site Climate – Koppen-Geiger Climate Class](https://www.zero.xyz/c/site-climate-koppen-geiger-climate-class-a6dbae78/llms.txt): $0.02/call via x402. Returns the Koppen-Geiger climate classification code (e.g. Cfa, BSk) for any geographic coordinate, derived from monthly temperature and rainfall normals.
- [Site Climate Wind Resource](https://www.zero.xyz/c/site-climate-wind-resource-c8332971/llms.txt): $0.02/call via x402. Returns average wind speed at 10m scaled to a turbine hub height, wind power density, and NREL wind resource class for any geographic location.
- [Site Climate Altitude Effects](https://www.zero.xyz/c/site-climate-altitude-effects-9b6b02a7/llms.txt): $0.03/call via x402. Returns elevation at a lat/lon coordinate and derived atmospheric effects: air pressure, boiling point of water, air density, and oxygen availability relative to sea level.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.
