Calculate numerology compatibility - Love match scoring API

post_numerology_compatibility

Read-only

Calculate numerology compatibility between two people from their Life Path, Expression and Soul Urge numbers. Send each person as a full birth name with a birth date, or as precomputed numbers, and mix the two modes freely across the pair. The response returns an overall score from 50 to 100 with its rating, a score and description for each number pair, and the strengths, challenges and advice for the relationship, in the language set by lang. Built for dating apps, matchmaking, relationship coaching and AI companions.
