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.

WebP Format

All logos served in WebP format — 25-35% smaller than PNG with full transparency support.

Code Examples

Production-ready code you can copy and paste into your project.

URL Generation

// Simple URL generation
function getLogoUrl(domain: string): string {
  return `https://logos-api.apistemic.com/domain:${domain}`;
}

Fetch with Error Handling

// Fetch with error handling
async function fetchLogo(domain: string): Promise<Blob> {
  const response = await fetch(
    `https://logos-api.apistemic.com/domain:${domain}`
  );

  if (!response.ok) {
    throw new Error(`Failed to fetch logo: ${response.status}`);
  }

  return response.blob();
}

// Create object URL for display
const blob = await fetchLogo('stripe.com');
const imageUrl = URL.createObjectURL(blob);

Free with Attribution

The logo API is completely free. Just add a visible attribution link.

Logos by <a href="https://logos.apistemic.com">apistemic logos</a>

Server-side? Use a User-Agent with contact info and limit to 1 rps. We verify attribution. Don't use rel="nofollow". See full rules.
