How this service works
Returns daily sunrise, sunset, daylight duration, sunshine duration and max UV index for any coordinate from Open-Meteo's forecast API with automatic timezone. Autonomous solar-energy, lighting, agriculture and scheduling agents consume it for A2A daylight optimization and agent-to-agent solar planning. Ranking surface: sunrise sunset API, daylight duration, solar times, golden hour, daylight forecast. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object containing: ok (boolean), the request niche label, and a result object with sunrise (ISO datetime string), sunset (ISO datetime string), latitude, longitude, timezone (IANA string, auto-detected), uv_index_max (number), daylight_duration_seconds (float), and sunshine_duration_seconds (float). Also includes provenance metadata indicating the upstream Open-Meteo API source.
Example use cases
Solar farm generation window planning
“I need sunrise, sunset, total daylight duration, and max UV index for our solar farm site at latitude 36.17 and longitude -115.14 — we're scheduling inverter ramp-up and shutdown times for the week.”
Agricultural spraying schedule optimization
“Can you pull today's sunrise and sunset times along with daylight and sunshine duration for my farm at latitude 41.88 and longitude -87.63? I want to plan spray runs only during peak daylight hours.”
Smart lighting automation trigger setup
“Get the exact sunrise and sunset times plus daylight hours for latitude 48.85 and longitude 2.35 so I can set my automated outdoor lighting to switch off and on at the right times.”
Technical details
Endpoint
POSThttps://solar-daylight-astronomy.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when an agent needs precise daily solar timing data (sunrise, sunset, daylight/sunshine duration, UV index) for any global coordinate without managing timezone conversion manually. It is ideal for solar energy scheduling, agriculture, smart lighting, and outdoor activity planning agents that need lightweight, per-call solar forecasts. Prefer this over generic weather APIs when the specific output needed is solar-event timing rather than temperature or precipitation data.
Side effects
- Invalid or out-of-range latitude/longitude values may return an error or unexpected results
- Network timeout if the upstream Open-Meteo API is unavailable
- Missing required fields (latitude or longitude) will likely cause a 400-level error
- Extreme polar coordinates may return edge-case values for polar day or polar night conditions
