  res.on('data', (chunk) => data += chunk);
  res.on('end', () => console.log(JSON.parse(data)));
});

req.end();

Authentication

The Exchange Rate API requires authentication via API key. Include your API key in the request header:

X-API-Key: your_api_key_here

GraphQL AccessALPHA

Access Exchange Rate through GraphQL to combine it with other API calls in a single request. Query only the exchange rate data you need with precise field selection, and orchestrate complex data fetching workflows.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

POST https://api.apiverve.com/v1/graphql

query {
  exchangerate(
    input: {
      currency1: "USD"
      currency2: "EUR"
    }
  ) {
    currency1
    currency2
    exchangeRate
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Exchange Rate API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Exchange Rate directly from browser-based applications without proxy servers.

Browser Usage: You can call Exchange Rate directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Learn more about CORS support →

Rate Limiting

Exchange Rate API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Exchange Rate users.

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Exchange Rate response includes headers to help you track your usage:

Handling Rate Limits

Free Plan: When you exceed your rate limit, Exchange Rate returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for Exchange Rate:

• Monitor the rate limit headers to track your Exchange Rate usage (Free plan only)
• Cache exchange rate responses where appropriate to reduce API calls
• Upgrade to Pro or Mega for guaranteed no-throttle Exchange Rate performance

Note: Exchange Rate rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Exchange Rate on Free tier.

Error Codes

The Exchange Rate API uses standard HTTP status codes to indicate success or failure:
