Overview

JSON proxy endpoints for the UniRate API. Mount the engine to expose them:

mount UniRateRails::Engine => "/unirate"

then:

GET /unirate/rate?from=USD&to=EUR
GET /unirate/convert?from=USD&to=EUR&amount=100
GET /unirate/currencies

The API key never leaves the server — it lives in the engine configuration, not in the browser. Typed UniRate errors are mapped back to sensible HTTP statuses.
