A lightweight WordPress plugin to display exchange rates per 1 EUR using the Fixer.io API.

Features

  • Shortcode support
  • Caching with WordPress transients
  • Flags and currency symbols
  • Optimized for Fixer free plan (100 requests/month)

Usage

Use the shortcode anywhere in posts, pages, or theme templates:

[currency_rate code="USD"]
[currency_rate code="JPY"]
[currency_rate code="RUB"]
[currency_rate code="CNY"]

Each shortcode will display the current exchange rate with the currency symbol and flag.

Example Output

🇺🇸 1.09 $ 🇯🇵 157.32 ¥ 🇷🇺 102.45 ₽ 🇨🇳 7.22 ¥

(Values are updated once per 24 hours by default to stay under the free plan limit.)

FAQ

Q: Does this plugin expose my API key? A: No. All API calls are handled server-side and your API key is never sent to the browser.

Q: How often does it update? A: Exchange rates are cached for 24 hours using WordPress transients to stay safe with the Fixer free plan.

Q: Can I display multiple currencies at once? A: Yes, just add multiple [currency_rate code="XXX"] shortcodes where needed.
