Introducing the Osintly Logo Service

One URL. Any domain. No auth required.

We quietly shipped something we kept using internally and never documented: a logo resolution API. Today we're making it public.

https://logos.osint.ly/{domain} — that's it.

What it does

You send a GET request with a domain. You get back a logo image — PNG, SVG, or ICO, depending on what's available. No redirects, no wrappers, no JSON envelope. Just the image, served directly from the edge.

https://logos.osint.ly/github.com
https://logos.osint.ly/stripe.com
https://logos.osint.ly/openai.com

We also strip www. automatically, so www.github.com resolves to the same thing as github.com.

Why we built it

Inside Osintly, every investigation card that involves a domain or company shows a logo. We needed a fast, reliable way to resolve those logos without hammering external services or bloating our backend. So we built our own.

After using it in production for a while, we realized there was no good reason to keep it internal. If you're building any kind of tool that deals with domains — OSINT tooling, threat intel dashboards, link previews, contact enrichment — you probably need this too.

No API key. No auth. CORS enabled.

The service is fully open:

Drop it anywhere

<!-- HTML -->
<img src="https://logos.osint.ly/github.com" alt="GitHub logo" />

// React
<img src={`https://logos.osint.ly/${domain}`} alt={`${domain} logo`} />

// JavaScript
const res = await fetch('https://logos.osint.ly/stripe.com');
const blob = await res.blob();

/* CSS */
.logo {
  background-image: url('https://logos.osint.ly/github.com');
}

HTTP responses

Response headers

Every successful response includes:

The X-Logo-Source header tells you where the logo came from — useful for debugging or understanding coverage.

Rate limiting

The service allows 1,000 requests per minute per IP on non-cached requests. Cache hits don't count toward this limit — and given the long TTLs, most requests in practice will be cached.

If you exceed the limit:

HTTP 429 Too Many Requests
Retry-After: 60

Start using it

No signup. No API key. No docs to read beyond this post.

If you build something with it or run into edge cases (pun intended), let us know — we're on X/Twitter and always reading.
