What is apistemic logos?

A free logo API that returns company logos by domain or LinkedIn slug.

Any Company

Fetch logos for any domain — from Fortune 500 to startups. Just pass the domain and get a logo.

No API Keys

No registration, no authentication, no rate limits for reasonable usage. Just HTTP requests.

  def logo_url(domain)
    "https://logos-api.apistemic.com/domain:#{domain}"
  end
end

ERB Template

<%= image_tag logo_url(@company.domain), alt: "#{@company.name} logo" %>

Server-side Fetch

# For caching logos or server-side processing
require 'net/http'

def fetch_logo(domain)
  uri = URI(logo_url(domain))
  req = Net::HTTP::Get.new(uri)
  # Include contact info so we can reach you if needed
  req['User-Agent'] = 'MyApp ([email protected])'

  Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) do |http|
    http.request(req).body
  end
end
