# Lookup by ticker

> Resolve a stock ticker to a company profile.

Use `type: "by_ticker"` for a public company. Include the exchange when a symbol could refer to more than one listing.

## Request

Send this body to `POST /brand/retrieve`. See the [Quickstart](/quickstart) for authentication and SDK setup.

```json theme={null}
{
  "type": "by_ticker",
  "ticker": "AAPL",
  "ticker_exchange": "NASDAQ"
}
```

The default exchange is NASDAQ. The [reference](/api-reference/brand-intelligence/brand) lists accepted exchanges and ticker constraints.

## Check the listing

Compare `brand.stock` and `brand.domain` with the requested company before saving the result. Preserve the ticker and exchange together as the lookup key.

An unresolved symbol can return `400 NOT_FOUND`. Correct its exchange or use [lookup by domain](/brand/lookup-by-domain) when you have the website.
