# Get a single exchange rate pair

`GET /rate/{base}/{quote}`

Returns the blended exchange rate for a single currency pair. Without a date param, returns the latest rate. A same-currency pair returns the identity rate of 1.

## Path parameters

- `base` string, required
- `quote` string, required

## Query parameters

- `date` string, date
- `providers` string

## Response `200`

Exchange rate

- Rate
  - `date` string, date, required — The date of the rate
  - `base` string, required — Base currency code
  - `quote` string, required — Quote currency code
  - `rate` number, required — Exchange rate value
  - `providers` object[] — Per-provider rates for this pair. Present only when `expand=providers` is set. Each entry has the provider's observation date and published rate (rebased to the row's base). Entries with `excluded: true` did not contribute to the blended `rate` — either flagged as outliers by the consensus filter, or overridden by a currency peg. Omitted on synthesized peg rows where no provider published the quote.
    - `key` string, required — Provider key
    - `date` string, date, required — Provider observation date used for this entry
    - `rate` number, required — Provider's rate, rebased to the row's base
    - `excluded` boolean — Present and true when this entry did not contribute to the blended rate

## Other responses

- `404` — No data found
- `422` — Invalid request
