How this service works
Sunrise and sunset times in UTC for a location and date, with day length. Input: 'lat,lon' or 'lat,lon,YYYY-MM-DD'.
Output
A JSON object with the latitude, longitude, and date queried, plus UTC ISO-8601 timestamps for sunrise and sunset, the total day length in hours, and a note that times are in UTC (or null values if polar day or night conditions apply).
Example use cases
Outdoor event daylight planning
“I'm organizing an outdoor wedding in Florence, Italy (43.7696, 11.2558) on September 13, 2025 — can you tell me exactly what time sunrise and sunset will be in UTC and how many hours of daylight we'll have?”
Polar night research check
“I'm traveling to Tromsø, Norway (69.6489, 18.9551) on December 10, 2025 — will there be any daylight at all? What are the sunrise and sunset times in UTC?”
Photography golden hour lookup
“I want to do a sunrise photo shoot in Cape Town (−33.9249, 18.4241) on March 1, 2025 — what time does the sun come up and go down in UTC, and how long is the day?”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/sunrise-sunset?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise UTC sunrise/sunset times and day length for any geographic coordinate on any date, especially in automated agent workflows where a pay-per-call micro-payment model ($0.001 USDC via x402) is acceptable. Prefer it over weather APIs that include sunrise as a secondary field when solar timing is your primary need, and when you want clean, minimal JSON output without unnecessary weather data.
Side effects
- Invalid or out-of-range latitude/longitude returns an error
- Malformed date string (not YYYY-MM-DD) causes a parse error
- Polar day or night conditions return null for sunrise or sunset times
- Network timeout if the Render.com host is cold-starting
- Missing input field returns a validation error
