  UniRate is a read-only reference-data API with no persistent, id-addressable resources.
  There are no foreign-key relationships between entities — each endpoint returns a
  self-contained value or map. The "entities" below are response value objects, not stored
  records, so relationships are compositional (has-one/has-many by embedding) rather than by id.
entities:
- name: Rate
  description: A single exchange rate as a decimal string (SingleRate.rate).
- name: RatesMap
  description: Map of ISO 4217 currency code -> rate string.
- name: ConversionResult
  description: A converted amount as a decimal string (SingleResult.result), or a map (ResultsMap).
- name: CurrenciesList
  description: Array of supported ISO 4217 currency codes.
- name: VatEntry
  description: One country's VAT record (country_code, country_name, vat_rate).
- name: VatRatesAll
  description: total_countries + date + map of country_code -> VatEntry.
- name: TimeSeries
  description: base/amount/date-range + data map of date -> (currency -> rate).
- name: HistoricalLimitEntry
  description: Per-currency coverage window (earliest_date, latest_date, total_days, description).
- name: HistoricalLimits
  description: total_currencies + data_source + map of currency -> HistoricalLimitEntry.
relationships:
- from: VatRatesAll
  to: VatEntry
  type: has_many
  via: vat_rates (keyed by country_code)
- from: HistoricalLimits
  to: HistoricalLimitEntry
  type: has_many
  via: currencies (keyed by currency code)
- from: TimeSeries
  to: RatesMap
  type: has_many
  via: data (keyed by date)
identifiers:
  note: >-
    No opaque/prefixed resource ids. Natural keys only — ISO 4217 currency codes and ISO 3166
    country codes. Dates are YYYY-MM-DD.
