Install

No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:

wp plugin install https://github.com/unirate-api/unirate-currency-converter/archive/refs/heads/main.zip
Readme github.com/unirate-api/unirate-currency-converter ↗

WordPress plugin — live currency conversion in posts, pages, and blocks. Powered by UniRate API.

Features

  • Gutenberg block — drag-and-drop currency converter with block-editor sidebar controls.
  • Three shortcodes — [unirate_rate], [unirate_convert], [unirate_widget].
  • API key stays server-side — requests are proxied through /wp-json/unirate/v1/; the key is never exposed to visitors.
  • WP transient caching — 1-hour cache out of the box, zero extra database writes per page load.
  • Zero PHP runtime dependencies — uses wp_remote_get() only; no Composer packages needed on your server.

Installation

  1. Download the plugin zip from Releases and upload via Plugins → Add New → Upload Plugin, or install directly from the WordPress Plugin Directory.
  2. Activate via Plugins → Installed Plugins.
  3. Go to Settings → UniRate and enter your UniRate API key.

Shortcodes

[unirate_rate from="USD" to="EUR"]

Server-rendered exchange rate at page load.

1 USD = 0.9235 EUR

[unirate_convert from="USD" to="EUR" amount="100"]

Server-rendered converted amount.

92.35 EUR

[unirate_widget from="USD" to="EUR" amount="1"]

Interactive currency converter. Visitor enters an amount, clicks Convert, and the result loads instantly via the local REST proxy — no API key exposed.

Gutenberg block

Search for UniRate Currency Converter in the block inserter (Widgets category). Use the sidebar panel to set:

  • Display style — widget / rate / converted amount
  • From / To currency — 3-letter ISO codes
  • Amount

REST endpoints

The plugin registers these endpoints on your site (all GET, public):

Endpoint Params Response
/wp-json/unirate/v1/rate from, to {"rate": 0.9235}
/wp-json/unirate/v1/convert from, to, amount {"result": 92.35}
/wp-json/unirate/v1/currencies — {"currencies": ["USD", "EUR", ...]}

Your API key is read from wp_options server-side — it never appears in these responses or in page HTML.
