Add Custom Currency Converter Widget

The Problem

A static "approximate rate" table goes stale within days — this widget pulls live rates so the numbers your visitors see are actually current.

About this problem

A live currency converter fetches current exchange rates from an API when the page loads, then uses them for conversion in the visitor's browser. The choice of source matters: free tiers often limit the number of requests, update rates only daily, or require an API key that should not be exposed in public code. A cache on the server can reduce calls and keep the widget working if the API is briefly unavailable.

People look for this when a static table of rates is out of date and they want visitors on travel, import or pricing pages to see current figures. Rates shown are indicative and not guaranteed for actual transactions.

What's Included

• A converter widget supporting the currencies you specify
• Connected to a live exchange rate source, updating automatically
• Clean, responsive design embedded into your chosen page
• Testing conversion accuracy against a known source

What's NOT Included

• Ongoing costs of any paid exchange-rate API, if a free-tier source isn't sufficient for your volume
• Historical rate charts (different, larger feature)
• Payment processing in foreign currencies (separate, see Stripe service)

How It Works

1. I agree the list of currencies and where on the site the widget should appear.
2. I choose a suitable exchange-rate source based on your expected traffic and update frequency needs.
3. I build the widget in HTML, CSS and JavaScript, with a server-side proxy or caching step where an API key must be kept private.
4. I handle failures gracefully, with a clear message or the last known rates if the source is unreachable.
5. I make the layout responsive and embed it in your chosen page.
6. I compare results with an independent source to check the conversion accuracy.

In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.

Frequently Asked Questions

Can I add a live currency converter to my website?

Yes, using a live exchange-rate source and a small widget embedded on the page.

Are the rates exact?

They are indicative market rates from the source I connect, not guaranteed rates for actual transactions.

Do I have to pay for the exchange rate data?

Many free sources are enough for modest traffic. If your volume needs a paid API, that cost is yours.

Can it show historical charts?

No. Charts of historical rates are a different, larger feature.

Does this let me accept payments in other currencies?

No. Payment processing is separate; see the Stripe service for that.

How often do the rates update?

That depends on the source, which can range from every few minutes to once a day. I tell you what the chosen source offers.
