Use an exchange lookup when you show where a security trades, such as in a brokerage, a market dashboard, or a listing page.

​
Exchange codes

Pass the exchange code. Case does not matter, so nyse and NYSE return the same logo. An exchange code is not the suffix you add to a ticker. To get a listed company’s logo, use the stock ticker lookup, such as /ticker/AZN.L.

​
How an exchange resolves

The CDN maps the code to the domain of the company that operates the exchange, then returns that company’s logo. Exchanges with the same operator return the same logo. For example, AMEX returns the NYSE logo, and the Euronext markets return the Euronext logo. An exchange code that Logo.dev does not know returns 400 Bad Request, not a monogram, whatever fallback is set to. See Errors. For the other parameters, see the Logo CDN overview.
