Build with the NumroQ API

The NumroQ API gives developers, agencies and product teams instant access to a large library of numerology, astrology and divination calculators through a single, well-structured REST interface. Instead of researching each tradition, coding its rules and hosting an astronomical ephemeris, you send a short request and receive a clean JSON response you can display in a web app, a mobile app, a chatbot or a WordPress site. Every calculator is versioned and consistent, so once you learn one endpoint you can call them all.

The same engine powers three products: the raw REST API for custom builds, two WordPress plugins for no-code embedding, and a complete white-label website you can brand and resell. You can start on the free plan, validate your idea, and upgrade only when your traffic grows. There are no setup fees and no long-term contracts, so the API scales with you from a weekend project to a production service.

What you can build

Developers use the NumroQ API to power a wide range of products without becoming experts in every tradition first. Because the results come back as structured data, you are free to design any interface on top of them.

• Numerology and astrology websites that show a life path number, birth chart, daily horoscope or compatibility score on demand.
• Mobile apps that read a date of birth or name and return a personalised reading in seconds.
• Chatbots and AI assistants that answer questions like "what is my destiny number" with a real calculation rather than a guess.
• Membership sites and lead magnets that offer a free report to capture sign-ups, then upsell a deeper paid reading.
• Print-on-demand and gifting products that turn a birth date into a personalised chart or keepsake.

Why build on the NumroQ API

Building these calculators yourself is slow and error-prone. Astrology in particular needs an accurate ephemeris, time-zone handling and house systems; numerology spans many traditions, each with its own letter values and reduction rules. The API does that work for you and keeps it correct over time.

• One API, many systems: Western and Vedic astrology, Pythagorean and Chaldean numerology, Abjad, Gematria, Ba Zi, tarot and more.
• Real astronomy under the hood, so birth charts and planetary positions are accurate, not approximated.
• Clean, predictable JSON that is easy to cache and render in any language or framework.
• A generous free tier and clear paid plans, so costs stay predictable as you grow.
• Three ways to ship: the raw API, ready-made WordPress plugins, or a complete white-label website.
