The best numerology API, compared

Why Simple Numerology API is the best numerology API

• The simplest. One POST with a name and a birthdate returns the complete Pythagorean chart, 47 fields, in one response. No endpoint per number, no credits to budget, no chart assembled from a dozen calls.
• The easiest to integrate. A free key in under a minute with no card, an OpenAPI 3.1 contract, Python and JavaScript SDKs, a Postman collection and a hosted MCP server for AI assistants.
• Fast. 0.15 ms p99 calculation time per chart, measured over 12,000 charts, and up to 100 charts in a single batch request.
• The best calculations. Every convention is documented, master numbers are reduced the canonical way, accents and Russian Cyrillic are valued correctly, and every response shows the letters it counted. The default output is frozen under /v1/, so a number never changes under you.

The best calculations

Numerology sources disagree on whether Y is a vowel, whether names are reduced together or one by one, and how accents and other scripts are valued, so APIs can return different numbers for the same person. Simple Numerology API settles every one of these questions in public:

• Documented conventions. Every rule is in the reference, and the contested ones can be changed per request and are echoed back in conventions.
• Master numbers done right. The Life Path reduces month, day and year separately, so it never invents a false 11 or 22 the way the add-every-digit shortcut does.
• Real names. Accents are folded, Russian Cyrillic is valued with the Russian table, and computed_name shows exactly which letters counted.
• Frozen output. The default output is pinned byte for byte by a golden test file, so an integration never breaks because a number changed.

Run any name through the ten-point checklist to see the difference.

Your words, not ours

Simple Numerology API returns numbers, not canned paragraphs. Your app describes each number in its own voice and in every language it supports, instead of showing the same sentences as every other app on the same provider. If you want a starting point, the free numerology calculators and Life Path meanings on this site show how.
