How this service works
Sunrise sunset times. Computes sunrise, sunset, solar noon, day length (seconds), and civil / nautical / astronomical twilight begin & end for any latitude/longitude on any date. Also covers golden hour, dawn / dusk, and full astronomy-times. UTC ISO8601 strings. Wraps sunrise-sunset.org's public API — no auth, commercial-OK.
Output
A JSON object with UTC ISO8601 timestamps for: sunrise, sunset, solar noon, day length in seconds, civil twilight begin and end, nautical twilight begin and end, astronomical twilight begin and end, golden hour start and end, dawn, and dusk — all computed for the requested latitude/longitude and date.
Example use cases
Example prompt

Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/astro-timesWhen to prefer
Use this endpoint when you need precise solar event times (sunrise, sunset, twilight phases, golden hour) for any global location and date. Prefer this over a weather API that only gives sunrise/sunset, because this provides the full astronomy suite including all six twilight boundary times and day length. No authentication is required and commercial use is permitted.
Side effects
- Invalid or out-of-range latitude/longitude returns an error
- Malformed or missing date parameter causes a bad request response
- Upstream sunrise-sunset.org API unavailable causes a timeout or 502 error
- Date far outside supported range may return null or error values
- Network issues with the Cloudflare Worker may cause intermittent failures
