Quick Code Example

Here's how to make your first free API call:

// Node.js / JavaScript Example
const response = await fetch('https://vedika.io/api/v1/horoscope/daily', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_FREE_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    sign: 'aries',
    date: '2025-12-22'
  })
});

const horoscope = await response.json();
console.log(horoscope.prediction);
# Python Example
import requests

response = requests.post(
    'https://vedika.io/api/v1/horoscope/daily',
    headers={
        'Authorization': 'Bearer YOUR_FREE_API_KEY'
    },
    json={
        'sign': 'aries',
        'date': '2025-12-22'
    }
)

horoscope = response.json()
print(horoscope['prediction'])

Cache results for 24 hours to stay within limits

Pro Tip: Reduce Production Costs with Caching

When you move to production, implement smart caching to reduce API costs. Daily horoscopes don't change throughout the day - cache them for 24 hours. Birth charts never change - store them permanently. Caching can reduce your bill by 80-90%!

Best Practices for Using FREE Sandbox

1. Implement Smart Caching

Smart caching is essential for keeping production costs low:

  • Daily horoscopes: Cache for 24 hours - they don't change
  • Birth charts: Store permanently - birth data never changes
  • Panchang data: Cache by date - same day = same results
  • Use Redis or localStorage: Reduce redundant API calls
// Example caching with localStorage
const cacheKey = `horoscope_${sign}_${date}`;
const cached = localStorage.getItem(cacheKey);

if (cached) {
  return JSON.parse(cached);
}

const data = await fetchFromAPI();
localStorage.setItem(cacheKey, JSON.stringify(data));
return data;

2. Secure Your API Keys

Never expose your API key in frontend code:

DON'T DO THIS:

// ❌ BAD: API key visible in browser
const API_KEY = 'vdk_live_abc123...';
fetch(url, { headers: { 'Authorization': API_KEY } });

DO THIS INSTEAD:

// ✅ GOOD: Call from backend
// Backend (Node.js)
app.post('/api/horoscope', async (req, res) => {
  const data = await fetch(VEDIKA_URL, {
    headers: { 'Authorization': process.env.VEDIKA_API_KEY }
  });
  res.json(data);
});

3. Handle Rate Limits Gracefully

FREE Sandbox allows 1 request/second. Implement proper error handling:

async function fetchWithRetry(url, options, retries = 3) {
  try {
    const response = await fetch(url, options);

    if (response.status === 429) {
      // Rate limit hit
      if (retries > 0) {
        await new Promise(r => setTimeout(r, 1000));
        return fetchWithRetry(url, options, retries - 1);
      }
      throw new Error('Monthly quota exceeded');
    }

    return await response.json();
  } catch (error) {
    console.error('API Error:', error);
    throw error;
  }
}

4. Monitor Your Usage

Track your API consumption to avoid surprises:

  • Vedika Dashboard: Real-time usage statistics available
  • Log API calls: Keep count in your application database
  • Set up alerts: Get notified when approaching 10-query limit
  • Plan upgrades: If hitting limits, Starter plan is only $12/month for 1,000 queries

Common Mistakes to Avoid

Mistake #1: Not Caching Results

Problem: Making the same API call multiple times for identical data wastes your free queries.

Impact: You'll exhaust your 10 queries in days instead of lasting a month.

Solution: Implement caching for at least 24 hours for horoscopes and permanent storage for birth charts. Use Redis, localStorage, or database caching.

Mistake #2: Exposing API Keys in Frontend

Problem: Hardcoding API keys in JavaScript makes them publicly accessible. Anyone can view your source code and steal your key.

Impact: Your API key could be used by others, exhausting your quota or worse - if you upgrade, they'll charge to your account!

Solution: Always call Vedika API from your backend server. Use environment variables (.env file) to store keys securely. Never commit keys to Git.

Mistake #3: Testing in Production

Problem: Using FREE Sandbox queries for debugging and testing reduces available quota for actual users.

Impact: Real users get errors when your testing exhausts the monthly limit.

Solution: Use mock data during development. Create a fixture file with sample API responses. Save free queries for production testing only.

Mistake #4: Ignoring Rate Limits

Problem: FREE Sandbox allows 1 request/second. Making rapid consecutive calls triggers temporary blocks.

Impact: Your app gets 429 errors and users see failures.

Solution: Implement request queuing with a 1-second delay between calls, or batch requests where possible. Add exponential backoff for retries.

Mistake #5: Not Planning for Scale

Problem: Building your entire production app on the FREE Sandbox without upgrade path.

Impact: When you get popular, you can't serve users and lose momentum.

Solution: FREE Sandbox is for testing and MVPs. Plan to upgrade to Starter ($12/mo) before launch. Design your architecture to handle tier transitions seamlessly.

Advanced Features Available on All Plans

Unlike other APIs that lock premium features behind paywalls, Vedika gives you access to advanced capabilities on every plan. You're only limited by wallet credits, not feature access:

AI-Powered Natural Language Queries

Ask questions in plain English instead of learning complex API endpoints:

Examples:

"When should I start a new business?"

"What gemstone is best for me?"

"Is this a good time to get married?"

This feature alone is worth $20-30/month on other platforms!
