    Localize storefront prices in the shopper's currency at page-render or
    checkout time. Caches /live quotes per source currency and falls back to
    /convert for one-off pair lookups.
spec:
  uses:
    - sharedCapability: currencylayer-shared
      operations: [getLive, convertCurrency, listCurrencies]
  preconditions:
    - description: Storefront base currency configured (typically USD or EUR).
    - description: Caller subscription on Basic or above for HTTPS, source-switching, and /convert.
  workflow:
    - step: warmSymbolCache
      operation: listCurrencies
      purpose: Cache the full currency catalog (24h+ TTL).
    - step: refreshLiveQuotes
      operation: getLive
      parameters:
        source: "{{ input.storeCurrency | default: 'USD' }}"
        currencies: "{{ input.targetCurrencies }}"

      operation: convertCurrency
      parameters:

    notes: |
      Currencylayer charges per request, so storefronts should cache /live
      results for at least the plan's refresh cadence (60 min on Basic, 10 min
      on Professional, 60 sec on Enterprise+) to avoid quota burn.
