Complete Core Numerology Numbers API Documentation
Everything developers need to integrate professional numerology calculations
What is the Core Numerology Numbers API and how does it work? The Core Numerology Numbers API calculates all five essential numerology numbers in a single API call: Life Path, Destiny/Expression, Soul Urge, Personality, and Maturity numbers. Unlike simple calculators that just give you numbers, our API provides complete professional interpretations, multiple calculation methods (Pythagorean and Chaldean), and proper handling of master numbers (11, 22, 33). Here's how it works in 3 simple steps: (1) You send a person's full name and birth date via HTTP request, (2) Our API processes the data in parallel using traditional and modern numerology methods, (3) You receive a comprehensive JSON response with all numbers, interpretations, and additional insights in under 200ms. The difference? While competitors offer basic number calculations, we deliver a complete numerological profile including personality traits, life purpose analysis, career guidance, and emotional needs assessment - everything you need to build engaging personal development apps, dating platforms, or professional coaching tools.
What are Core Numerology Numbers?
Core numerology numbers are the five fundamental calculations that form the foundation of any numerological reading.
Think of them as the 'Big 5' personality traits but for numerology - each number reveals a different aspect of a person's life journey and character.
The Life Path number is calculated from your birth date and reveals your life's purpose - like a GPS for your soul's journey.
The Destiny/Expression number comes from your full name and shows your talents and potential career paths.
The Soul Urge number (from vowels in your name) reveals what truly motivates you deep inside.
The Personality number (from consonants) shows how others see you.
Finally, the Maturity number combines life path and destiny to show your ultimate life goals.
What makes our API special is master number detection.
The numbers 11, 22, and 33 are considered 'master numbers' with special spiritual significance.
Many simple calculators incorrectly reduce these to 2, 4, and 6, but we preserve their true power.
We also support both Pythagorean (A=1, B=2) and Chaldean (older, A=1, B=2, but no 9) calculation methods, giving you complete flexibility for different numerological traditions.
Professional numerologists charge $50-200 for manual calculations that take hours.
Our API does the same work in milliseconds, with interpretations from certified numerology experts.
It's like having a team of professional numerologists available 24/7 via a simple API call.
How much does the Core Numerology API cost?
The Core Numerology API costs $11/month for 5,000 calculations - that's just 22 cents per 100 calculations.
Compare that to hiring a professional numerologist for $50-200 per reading, or competitors charging $49-199/month for basic services.
Our free tier includes 100 monthly calculations with no credit card required, perfect for testing and small projects.
Here's the math: If you're building a dating app with 10,000 users each getting a numerological profile, that costs you $22 total with our Starter plan.
A competitor would charge you $199/month for the same volume.
That's 90% savings with better features like master number support and professional interpretations.
For high-volume applications like social media platforms or enterprise HR tools, our Business plan at $99/month handles 220,000 calculations - equivalent to profiling an entire company's workforce or serving hundreds of thousands of users.
Enterprise customers get unlimited calculations with dedicated support, custom endpoints, and white-label options.
Pricing scales with your success.
Start free, upgrade as you grow, and never pay for features you don't use.
No setup fees, no minimum contracts, and you can downgrade anytime.
Plus we offer volume discounts for educational institutions and nonprofits - because personal development shouldn't be limited by budget.
How do I integrate the Core Numerology API into your app?
Integrating the Core Numerology API is literally 3 lines of code.
No complex setup, no weird configuration files, no PhD in numerology required.
Here's how: (1) Get your free API key in 30 seconds, (2) Install our SDK with 'npm install astroapi' or use direct HTTP calls, (3) Run your first calculation.
For React developers: Import our hook, pass name and birth date, get results.
The API handles all edge cases automatically - leap years, international name formats, special characters, everything.
We even validate input data and give helpful error messages if something's wrong.
The response format is developer-friendly JSON with consistent structure.
Each number includes the raw value, calculation breakdown (so users can see how it was calculated), professional interpretation, and additional metadata.
Want to show users exactly how their Life Path number was calculated? We include the step-by-step math: '1990-06-15 = 1+9+9+0+0+6+1+5 = 31 = 3+1 = 4'.
Need batch processing for user onboarding or data migration? Our bulk endpoint handles thousands of names simultaneously.
Building a mobile app? Our response size is only 2KB compressed on average.
Working with international users? We support Unicode names and provide interpretations in 9 languages.
Whatever your use case, we've got you covered with comprehensive documentation, code examples, and responsive support.
Life Path Number Calculation and Meanings
Your Life Path number is like your soul's GPS - it reveals your life's purpose and the journey you're meant to take.
Calculated from your birth date, it shows your natural talents, challenges you'll face, and your ultimate destiny.
Think of it as your spiritual job description written in the stars.
The calculation seems simple - add all digits in your birth date until you get a single digit - but there are important rules.
Master numbers 11, 22, and 33 should never be reduced because they carry special spiritual power.
For example, someone born 11/29/1975 would be: 1+1+2+9+1+9+7+5 = 35, 3+5 = 8, not a master number.
But someone born 11/2/1979 would be: 1+1+0+2+1+9+7+9 = 30, 3+0 = 3, then check if any intermediate sum was 11, 22, or 33.
Each Life Path number has different characteristics: Life Path 1s are natural leaders and innovators, 2s are peacemakers and cooperators, 3s are creative communicators, 4s are practical builders, 5s are freedom-loving adventurers, 6s are caring nurturers, 7s are spiritual seekers and analysts, 8s are ambitious achievers, 9s are humanitarian visionaries.
Master 11s are intuitive illuminators, 22s are master builders, and 33s are master teachers.
Our API doesn't just give you the number - it provides comprehensive life guidance including compatible career paths, relationship advice, personal challenges to overcome, and specific action steps for personal growth.
It's like a personal life coach based on ancient wisdom but delivered through modern technology.
Deep Dive into Destiny and Expression Number
Your Destiny number (also called Expression number) is calculated from your full birth name and reveals your natural talents, career potential, and life mission.
While your Life Path shows your journey, Destiny shows what you're meant to achieve.
It's like the difference between the road you're traveling and your final destination.
The calculation uses letter-to-number conversion: A=1, B=2, C=3, etc.
in Pythagorean, or the older Chaldean system where certain letters have different values and 9 is considered too sacred to use.
Your full legal birth name matters - not nicknames or married names - because that's the energy you were born with.
Each Destiny number indicates specific career paths and talents: Destiny 1s excel as entrepreneurs, CEOs, and innovators.
2s thrive as counselors, mediators, and team players.
3s shine as artists, writers, entertainers, and communicators.
4s succeed as architects, engineers, accountants, and systematic builders.
5s flourish in sales, travel, communications, and dynamic fields.
6s excel as teachers, healers, parents, and community leaders.
7s thrive as researchers, scientists, philosophers, and spiritual guides.
8s dominate in business, finance, real estate, and leadership positions.
9s serve as humanitarian leaders, artists, and global changemakers.
Our interpretations go beyond basic descriptions to offer specific career recommendations, entrepreneurial potential, leadership style analysis, and advice on maximizing natural talents.
We also include compatibility insights for business partnerships and team building - invaluable for HR applications and professional development platforms.
Soul Urge, Personality, and Maturity Number Analysis
Soul Urge, Personality, and Maturity numbers complete your core numerological profile, revealing the hidden layers of your character.
Soul Urge (calculated from vowels) shows your inner motivation - what truly drives you when nobody's watching.
Personality (from consonants) reveals your public mask - how others perceive you.
Maturity combines Life Path and Destiny to show your ultimate achievement in later life.
Soul Urge numbers reveal deep emotional needs: Soul Urge 1 craves independence and recognition as a leader, 2 needs harmony and partnership, 3 seeks creative expression and attention, 4 wants security and systematic progress, 5 desires freedom and variety, 6 needs to nurture and serve others, 7 seeks wisdom and spiritual understanding, 8 craves material success and recognition, 9 wants to serve humanity and have global impact.
Personality numbers show your outer image: Personality 1 appears confident and assertive, 2 appears diplomatic and cooperative, 3 appears creative and entertaining, 4 appears reliable and organized, 5 appears adventurous and dynamic, 6 appears caring and responsible, 7 appears mysterious and intellectual, 8 appears powerful and successful, 9 appears compassionate and wise.
Maturity numbers predict later-life focus and achievement.
This is where your Life Path journey meets your Destiny mission, showing what you'll be known for in your mature years.
Our API provides specific guidance for each combination, helping users understand their complete life arc from youth to maturity, making it perfect for life coaching apps and long-term personal development planning.
