Tanod skypeek Sun & Moon Calculator
x402
Tanod skypeek Sun & Moon Calculator is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-09).
Computes sunrise, sunset, twilight times, solar noon, and moon phase/rise/set for a given location and date, entirely offline using astronomical algorithms.

How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
A JSON object containing: full sun data (sunrise, sunset, solar noon, day length in hours, max altitude in degrees, civil/nautical/astronomical twilight dawn and dusk times, and a polar field explaining null rise/set when applicable), and full moon data (phase name, waxing boolean, moonrise, moonset, distance in km, age fraction, illumination fraction, and elongation in degrees). All times are ISO 8601 with timezone offset. Method and accuracy notes are included.
Example use cases
Photography golden hour planning
“I'm shooting outdoors in Paris (48.8566°N, 2.3522°E) on July 14, 2026. Can you tell me when sunrise, sunset, civil twilight, and solar noon are, using the Europe/Paris timezone?”
Nighttime stargazing window check
“I want to go stargazing near Denver (39.7392°N, 104.9903°W) on August 12, 2026. Can you tell me when astronomical twilight ends and what the moon phase and illumination will be that night? Use America/Denver timezone.”
Ramadan prayer time data prep
“What are the sunrise and sunset times for Karachi (24.8607°N, 67.0011°E) on March 15, 2026? Also include civil twilight times. Use Asia/Karachi as the timezone.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/space/sun-moon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise, locally-computed solar and lunar event times for any latitude/longitude and date without relying on a third-party ephemeris service. It is ideal for applications needing offline-safe, deterministic astronomical calculations with timezone-aware output. Prefer it over weather APIs (which don't provide astronomical data) or ephemeris-based services when sub-minute accuracy for twilight and within-3-minute moonrise/moonset accuracy is sufficient.
Side effects
- Missing required lat or lon fields returns a validation error
- Invalid IANA timezone string causes an error response
- Date outside the supported 1900–2100 range is rejected
- Polar locations may return null for sunrise/sunset with an explanation in sun.polar
- Moonrise or moonset may be null on days with no rise or set event
Input
