# Retrieve a market reference rate

`GET /rates`

## Request

- The document declares no server URL.
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/hevn-inc/apis/hevn-api/docs/rates/get.ts> (a function with typed inputs; its response is checked against the schema)

Convert one currency or token into another at the current market rate, before any transfer exists. Use it to show a price; the rate a transfer settles at comes from its own quote.

## Query parameters

- `from` string, required: ISO 4217 currency code or a token symbol.
- `to` string, required: ISO 4217 currency code or a token symbol.

## Response `200`

Successful Response

- RateView
  - `fromCurrency` string, required: Currency or token the rate converts from.
  - `toCurrency` string, required: Currency or token the rate converts to.
  - `rate` string, required: How many units of toCurrency one unit of fromCurrency buys.
  - `indicative` boolean: Always true: this is a market reference rate. A payout or incoming transfer is priced by its own quote.
