The API That Unlocks Real Compatibility

Here's how the magic works: Numerology reduces names and birthdates to single digits that reveal personality patterns.

For example, someone born March 21, 1992 has a calculated life path by adding the digits.

These numbers aren't random - they've been studied for thousands of years and show real personality traits.

Our API compares these core numbers between two people and creates a weighted compatibility score.

We look at 5 different dimensions: Life Path (core personality), Expression (communication style), Soul Desire (inner wants), Personality (how others see you), and Maturity (long-term potential).

Instead of just averaging them like basic calculators, we use advanced algorithms that know which combinations work better together.

Most compatibility calculators are basically as generic as horoscopes.

Ours is different because we actually look at the specific number combinations and their real-world implications.

For example, a Life Path 1 (independent leader) with a Life Path 2 (supportive partner) scores higher than two Life Path 1s (who might fight for control).

We've analyzed thousands of real relationships to see which number combinations actually work in practice, not just theory.

Our AI also considers cultural context - expression numbers from western names work differently than those from eastern name patterns.

Plus we provide specific advice for each pairing: what to watch out for, how to communicate better, even date activity suggestions that match your combined energy.

Integration is super easy - like adding any modern API to your app.

First grab an API key (takes 30 seconds), then make a POST request with two people's names and birthdates.

You get JSON back with compatibility percentages, detailed analysis, and relationship advice.

For React apps we recommend creating a custom hook like useCompatibility that handles the API call and caching.

The response contains everything: overall score (0-100%), individual dimension scores, personality insights for each person, and practical relationship advice.

Most developers have it running in 20 minutes including error handling and loading states.

Way easier than trying to implement numerology calculations yourself.

Dating apps that go beyond 'swipe on photos' see the biggest wins.

Think about it - users are tired of matching with attractive people who turn out incompatible.

Adding compatibility badges like '90% Communication Harmony' or 'Strong Long-term Potential' gives users a reason to message matches they'd otherwise skip.

Premium dating apps especially love this feature because it adds real value users will pay for.

We've seen apps increase message rates by 40% when they show compatibility insights upfront.

It also reduces user churn because people stick around when matches actually go somewhere.

Apps focused on serious relationships (not just hookups) get the most value from our detailed personality insights.

Business partnerships follow the same compatibility principles as romantic ones - some number combinations just work better together.

Our API can analyze potential business partners, team members, or even client relationships.

For example, two Expression 8s (both super ambitious) might create a powerful but competitive dynamic, while an Expression 3 (creative) paired with an Expression 4 (organized) creates perfect balance.

HR teams use this for team building, startups use it for co-founder compatibility, and sales teams use it to understand customer personalities.

We provide business-specific insights: communication styles for meetings, conflict resolution approaches, and even optimal task delegation based on numerological profiles.

It's like Myers-Briggs but based on actual mathematics.

Speed matters more than you think in dating apps.

Users have the attention span of goldfish - if the compatibility analysis takes 3 seconds to load, they've already swiped to the next person.

Our <300ms response time means compatibility scores appear instantly while users browse profiles.

This real-time feedback creates a more engaging experience where users actually pay attention to the insights instead of just the photos.

Fast APIs also enable cool features like compatibility notifications ('Someone with 95% compatibility just joined!') or real-time matching updates.

Slow APIs kill user experience and make features feel clunky.

Nobody wants to wait for love.
