Simply use an image tag, and the logos will load directly from our global CDN. This approach ensures you always display the most current logo versions without managing logo files yourself. Since our service is designed for hotlinking, please note that caching or storing the logo images locally is not supported. This snippet demonstrates how to retrieve a logo for stock ticker `AAPL`: ```html theme={null} AAPL logo (identification only, no affiliation) ``` By default, only the most popular exchanges are enabled on a new account. If you require access to additional exchanges, please contact us to enable them for you. ## Supported Ticker Formats The API supports a wide range of ticker formats across different exchanges and identification schemes. If no exchange or composite code is specified, `US` is assumed. For example, all of the following identifiers can be used to retrieve the logo for specified companies: ### Apple Inc * Standard Exchange Tickers: `AAPL` / `AAPL:US` * Example Exchange-Specific Tickers: `APC.DE`, `APC.F`, `APC:GR`, `AAPL34.SA`, `AAPL34:BZ` * Identification Numbers: * CUSIP `037833100` * SEDOL `2046251` * ISIN `US0378331005` * WKN `865985` ### Roche Holding AG (voting, non-voting, ADR) * Standard Exchange Tickers: `RO:SW`, `ROG:SW`, `RHHBY` / `RHHBY:US` * Example Exchange-Specific Tickers: `ROGN:MM`, `RHO6.F` * Identification Numbers: * CUSIP `S71103881`, `S71089189`, `771195104` * SEDOL `7110388`, `7108918`, `BYZHCK7` * ISIN `CH0012032113`, `CH0012032048`, `US7711951043` * WKN `851311`, `855167`, `891106` We continuously expand our coverage of global exchanges and ticker formats.
