Example use cases
Wedding night moon check
“We're getting married on September 13, 2025 — can you tell me what the moon phase will be that night and how bright it'll be?”
Photographer's golden hour planning
“I'm doing an outdoor night shoot on October 31, 2025 — what phase is the moon in and what percentage is it illuminated?”
Lunar calendar curiosity
“What was the moon phase on the day I was born, March 22, 1990? Was it a new moon, crescent, or full moon, and what was the lunar age?”

Choose this endpoint when you need a quick, cheap ($0.001 USDC) programmatic lunar phase lookup for any date without setting up astronomical libraries. Ideal for agents needing moon phase data to enrich event planning, photography scheduling, or calendar features without requiring a full ephemeris API.
Side effects
- Invalid or unparseable date format returns an error
- Missing date parameter defaults to current date or may return an error
