Switching from Brandfetch to Logo.dev is two swaps: point logo image URLs at img.logo.dev instead of the Brandfetch Logo CDN, and send Brand API calls to the Describe or Brand API. For a feature-by-feature view, see Logo.dev vs Brandfetch.

​
Migrate logo images

Swap the host and credential, then rename a few parameters. Brandfetch’s Logo CDN and Logo.dev’s image API are both URL-based, so that’s the whole change.
Brandfetch Logo CDN
https://cdn.brandfetch.io/domain/nike.com/w/128/h/128?c=CLIENT_ID
Logo.dev Logo API
https://img.logo.dev/nike.com?token=LOGO_DEV_PUBLISHABLE_KEY&size=128&format=png
Get your publishable key from the dashboard and pass it as token. Add format=png or format=webp explicitly: Logo.dev’s default is jpg, which has no transparency, unlike Brandfetch’s .png/.webp extensions.
Brandfetch’s type segment (/type/icon, /type/symbol, /type/logo) selects different asset shapes. Logo.dev’s image endpoint returns one canonical logo per domain; for the wide lockup Brandfetch calls its logo type, use the Brand API’s brandmark field (Pro and Enterprise) instead.
The common parameters map directly:
BrandfetchLogo.dev
/domain/nike.com/nike.com (drop the domain/ prefix)
/ticker/NKE, /isin/:isin, /crypto/:symbolSame paths: /ticker, /isin, /crypto
?c=CLIENT_ID?token=LOGO_DEV_PUBLISHABLE_KEY
/w/128/h/128size=128, or width and height (max 800)
/theme/darktheme=dark (the meaning changes, see below)
.png / .webp extensionformat=png / format=webp
/fallback/lettermarkfallback=monogram (the default)
/fallback/404fallback=404
One parameter changes meaning in the swap. Brandfetch’s /theme/... selects a light or dark logo variant; Logo.dev’s theme names the background you render on, so theme=dark keeps logos visible on dark backgrounds. Pick the value for your background instead of carrying the Brandfetch value over. See the Logo API parameters for the full list.

​
Migrate brand data

Brandfetch’s Brand API returns one JSON profile per domain. On Logo.dev, pick between two endpoints by depth and plan:
  • Describe API, on any paid plan, returns core company data: name, description, brand colors, socials, and the logo.
  • Brand API, on Pro and Enterprise, adds the brandmark and social banner images.
Both take your secret key (sk_…) in the Authorization header, where Brandfetch takes a bearer token:
Brandfetch Brand API
curl --header "Authorization: Bearer BRANDFETCH_API_KEY" "https://api.brandfetch.io/v2/brands/domain/nike.com"
Logo.dev Brand API
curl --header "Authorization: Bearer LOGO_DEV_SECRET_KEY" "https://api.logo.dev/brand/nike.com"
Logo.dev’s brand profile centers on visual assets and core company data: logo, brandmark, social banners, colors, description, and socials. If you depend on Brandfetch fields like fonts, company size, or industry, check the Describe and Brand responses against your needs before switching that call.
If you used Brandfetch to resolve a ticker, ISIN, or crypto symbol to a logo image, the image Logo API covers the same lookups directly: 
curl "https://img.logo.dev/ticker/NKE?token=LOGO_DEV_PUBLISHABLE_KEY"

Attribution

On the free tier, commercial use requires attribution wherever you display logos; personal projects don’t. Any paid plan removes it.
