What Astrology Features Users Want

Feature	User Demand	Implementation Complexity
Sun Sign Compatibility	Very High (Entry-level)	Low
36 Guna Matching (Kundali)	Very High (India)	Medium (with API)

How to Implement: Traditional vs. AI Approach

Traditional Approach (Complex)

With traditional astrology APIs, you need to:

Call birth chart API for User A
Call birth chart API for User B
Calculate 36 Guna scores manually
Check for Mangal Dosha in both charts
Check for Nadi Dosha
Calculate Bhakoot and other doshas
Synthesize results into a compatibility report

This requires deep astrology knowledge and multiple API calls.

Modern AI Approach (Simple)

With Vedika API, you simply ask:

// Single API call for complete compatibility analysis
const compatibility = await vedika.query({
  question: "How compatible are these two people for marriage?",
  birthDetails: {
    person1: {
      name: "Rahul",
      datetime: '1992-05-15T10:30:00+05:30',
      latitude: 28.6139,
      longitude: 77.2090,
      timezone: 'Asia/Kolkata'
    },
    person2: {
      name: "Priya",
      datetime: '1994-08-22T14:15:00+05:30',
      latitude: 19.0760,
      longitude: 72.8777,
      timezone: 'Asia/Kolkata'
    }
  }
});

console.log(compatibility.answer);
// Returns: Complete analysis including Guna score, doshas,
// compatibility percentage, and recommendations
            

                Key Advantage: The AI automatically calculates 36 Gunas, checks all doshas, analyzes planetary positions, and provides a human-readable compatibility report - all in one API call.
            

Implementation Guide for Matchmaking Platforms

Step 1: Collect Birth Details

During user registration or profile setup, collect:

Date of Birth - Required
Time of Birth - Required for accurate Kundali
Place of Birth - For latitude/longitude (use Google Places API)

// Example: Birth details form
<form>
  <input type="date" name="birthDate" required />
  <input type="time" name="birthTime" />
  <input
    type="text"
    name="birthPlace"
    placeholder="Enter city name"
    // Use Google Places Autocomplete
  />
</form>
            

Step 2: Show Compatibility on Match Cards

// Calculate compatibility score for each potential match
async function getMatchScore(currentUser, potentialMatch) {
  // Quick sun sign compatibility (free tier)
  const quickScore = getSunSignCompatibility(
    currentUser.sunSign,
    potentialMatch.sunSign
  );

  // Deep compatibility (premium feature)
  if (currentUser.isPremium) {
    const detailed = await vedika.query({
      question: "Give me a compatibility percentage and brief summary",
      birthDetails: {
        person1: currentUser.birthDetails,
        person2: potentialMatch.birthDetails
      }
    });
    return detailed;
  }

  return quickScore;
}
            

Step 3: Detailed Compatibility Report

When users click on a match, show detailed analysis:

// Full Kundali matching report
const fullReport = await vedika.query({
  question: `
    Provide a detailed marriage compatibility analysis including:
    1. 36 Guna score breakdown (Varna, Vashya, Tara, Yoni, Maitri, Gana, Bhakoot, Nadi)
    2. Any doshas present (Mangal, Nadi, Bhakoot)
    3. Overall compatibility percentage
    4. Relationship strengths
    5. Potential challenges
    6. Remedies if needed
  `,
  birthDetails: {
    person1: user1Details,
    person2: user2Details
  }
});

Technical Integration

Backend Integration (Node.js)

// routes/compatibility.js
const express = require('express');
const { VedikaClient } = require('@vedika-io/sdk');

const router = express.Router();
const vedika = new VedikaClient({
  apiKey: process.env.VEDIKA_API_KEY
});

router.post('/check-compatibility', async (req, res) => {
  const { user1Id, user2Id } = req.body;

  // Fetch users from database
  const user1 = await User.findById(user1Id);
  const user2 = await User.findById(user2Id);

  // Get compatibility from Vedika
  const result = await vedika.query({
    question: "Calculate marriage compatibility score and brief summary",
    birthDetails: {
      person1: user1.birthDetails,
      person2: user2.birthDetails
    }
  });

  // Cache result for future requests
  await CompatibilityCache.create({
    users: [user1Id, user2Id].sort(),
    result: result.answer,
    score: extractScore(result.answer)
  });

  res.json(result);
});

module.exports = router;
            

Privacy and Compliance

When collecting birth details, ensure:

Consent: Clearly explain why you need birth time/place
Optional: Allow users to skip and use just sun sign
