About Nicolas Perez | Simple Numerology API

I build and run Simple Numerology API: the calculation engine, its documented conventions, the free calculators and every guide on this site.

Why I built it

Numerology calculators and APIs disagree with each other. One counts Y as a vowel, another does not; one reduces the Life Path in parts, another adds every digit at once and invents master numbers that are not there; many silently drop accented letters. Developers building on them inherit those inconsistencies without knowing it.

Simple Numerology API settles each of those questions in public. Every convention is documented, the default output is frozen under /v1/, and every response shows the letters it counted. The same engine powers the free calculators on this site, so what you see here is what the API returns.

What I write about

How Pythagorean numerology is calculated, the edge cases that change a chart, and how to build numerology into an app: the blog, the Life Path meanings and the developer guides, starting with the numerology calculator API.
