2 min read

Introduction

Speed matters in financial apps. Currency rates change by the second, and stale data can kill the user experience. JuheAPI offers a reliable and easy-to-use interface to fetch real-time exchange rates.

In this post, you’ll see how to integrate JuheAPI’s exchange rate endpoint into your product and follow best practices to keep things fast, accurate, and production-proof.

Why JuheAPI for Financial Data

JuheAPI provides:

  • Reliable uptime for mission-critical use cases
  • Wide coverage of currencies and markets
  • Simple RESTful endpoints
  • Flexible subscription plans for scaling up

Getting Started with the API

Sign up and get your API key

  1. Go to JuheAPI website.
  2. Create an account.
  3. Generate your API key from the dashboard.

You’ll use this key for authentication in every request.

Base URL and endpoint structure

The base URL for the hub is: https://hub.juheapi.com/

For exchange rates, the endpoint is: https://hub.juheapi.com/exchangerate/v2/

All requests require an API key, usually sent as a query parameter or header.

Fetching Exchange Rates

Example request

To get exchange rates between USD and EUR: curl "https://hub.juheapi.com/exchangerate/v2/convert?apikey=YOUR_KEY&base=USD&target=EUR"

Parsing JSON responses

JuheAPI returns data in JSON like: {"result": {"from": "USD", "to": "EUR", "rate": 0.9234, "update_time": "2024-06-05 10:00:00"}} You can parse result.rate to perform calculations or display it in your app.

Best Practices for Production Use

Caching and rate limits

  • Cache responses for short periods to reduce API calls and improve speed.
  • Respect rate limits stated in your JuheAPI plan.
  • Use in-memory caching (Redis, Memcached) for performance.

Error handling

  • Check for HTTP status codes like 4xx or 5xx.
  • Implement retry logic with exponential backoff.
  • Monitor API latency in production.

Beyond Exchange Rates

JuheAPI also offers:

  • Precious metals prices
  • Stock data
  • Economic indicators
