How to use ISIN logos

Using the ISIN logo API is very simple, all you need is your publishable key from the Logo.dev dashboard.
Apple Logo
Here’s an example of how to implement an ISIN logo lookup for Apple on your website: 
<img src="https://img.logo.dev/isin/US0378331005?token=LOGO_DEV_PUBLISHABLE_KEY" alt="Apple ISIN logo" />
Anywhere you can use an image URL, such as Excel, Slack, or email, you can use this endpoint: 
https://img.logo.dev/isin/US0378331005?token=LOGO_DEV_PUBLISHABLE_KEY

​
How ISIN lookup works

We map ISIN codes to their corresponding company domains to retrieve the correct logo. This ensures you get the official brand asset for the security’s underlying company.

​
Supported ISINs

We support valid ISIN codes from all major global markets. The 12-character alphanumeric code typically consists of:
  • A two-letter country code (e.g., US, DE, GB)
  • A nine-character alphanumeric national security identifier
  • A single check digit
If you find an ISIN that doesn’t return the expected logo, please report it or submit an update via the dashboard.
