Frequently asked

Questions developers ask before integrating.

What's the difference between Pythagorean and Chaldean numerology?
Pythagorean assigns numbers 1–9 to letters in alphabetical order. Chaldean is older and uses a different letter-to-number mapping based on sound vibration; 9 is sacred and excluded from name calculation.
Which numbers does the API calculate?
Life Path, Destiny (Expression), Soul Urge, Personality, Birth Day, Maturity Number, Pinnacles, Challenges, Personal Year, Personal Month, plus karmic debt and karmic lessons.
Does it detect master numbers (11, 22, 33)?
Yes — master number detection is built in, including karmic debt numbers (13, 14, 16, 19) with classical interpretations.
Can I calculate compatibility between two people?
Yes. The compatibility endpoint scores Life Path, Destiny, and Soul Urge matches between two birth dates and returns a numeric score with narrative interpretation.
