URL Structure

The Logo API uses a structured URL format that allows you to customize logo retrieval through path and query parameters:

​
Short version

<img
  src="https://cdn.brandfetch.io/nike.com?c=BRANDFETCH_CLIENT_ID"
  alt="Logo by Brandfetch"
/>

​
Full version with all parameters

<img
  src="https://cdn.brandfetch.io/nike.com/w/400/h/400/theme/dark/fallback/lettermark/type/icon?c=BRANDFETCH_CLIENT_ID"
  alt="Logo by Brandfetch"
/>
To use Logo API, you must include your client ID with every request. To get your client ID, register for free from our Developer Portal.

​
identifier

Type: string Required Identifier to retrieve brand assets. Accepted formats:
  • Domain: nike.com
  • Brand ID: id_0dwKPKT
  • ISIN: US6541061031
  • Stock or ETF ticker: NKE
  • Crypto symbol: BTC, ETH (uppercase preferred)
To avoid potential naming collisions between identifier types, you can use explicit type routes with the pattern {type}/{identifier}:
  • domain/nike.com - Query by domain name
  • ticker/NKE - Query by Stock or ETF ticker
  • isin/US6541061031 - Query by ISIN code
  • crypto/BTC - Query by Crypto symbol
Examples: 
<img
  src="https://cdn.brandfetch.io/nike.com?c=BRANDFETCH_CLIENT_ID"
  alt="Logo by Brandfetch"
/>
If you omit the type prefix (e.g., nike.com instead of domain/nike.com), the API will auto-detect the identifier type. The detection order is: Domain → Stock or ETF ticker → ISIN → Crypto symbol. However, we recommend using explicit type routes to prevent collisions and ensure accurate results.
