# Get a provider

`GET /providers/{provider}`

One entry from `/providers`, by key (case-insensitive).

## Path parameters

- `provider` string, required

## Response `200`

Provider

- Provider
  - `key` string, required — Provider identifier
  - `name` string, required — Full provider name
  - `country_code` string, nullable — ISO 3166-1 alpha-2 country code
  - `rate_type` string, nullable — Official rate type as used by the source
  - `pivot_currency` string, nullable — Base currency for published rates
  - `data_url` string, uri, nullable — Link to the data source
  - `terms_url` string, uri, nullable — Link to terms of use
  - `start_date` string, date, nullable — Earliest available date
  - `end_date` string, date, nullable — Latest available date
  - `publish_cadence` 'daily' | 'weekly' | 'monthly' | 'quarterly' | 'null', nullable — How often the provider publishes rates. Determines the unit of publishes_missed: a count of days, ISO weeks, calendar months, or calendar quarters. Null for historical-only providers with no scheduled cadence.
  - `frequency` 'daily' | 'monthly' | 'quarterly' — The period each observation stands for, after SDMX FREQ. A daily value is dated on the day observed. A monthly or quarterly value is dated on the day it takes effect and stands for the period until the next one. Values coarser than daily never enter the blend: query them by provider.
  - `publishes_missed` integer, nullable — Number of expected publishes missed since end_date, in units of publish_cadence. For daily providers, counts scheduled publish days strictly between end_date and today. For weekly, monthly and quarterly providers, counts ISO weeks, calendar months or calendar quarters between the latest imported bucket and the bucket whose publish window has already started. Null when the provider has no scheduled cadence or no imported data.
  - `currencies` string[], required — Recognised currency codes within their valid date ranges covered by this provider
  - `unknown_currencies` string[] — Published codes absent from the currency registry. Available through provider rates but excluded from blends and the currency catalogue.
