Logo serving is free from trusted origins (embed <img> tags on your own site and it just works via the Referer header). For server-to-server requests, third-party embeds, or scripts, send an API key — see Authentication.

Add a logo to your app

That’s it. Logoo returns a high-quality WebP image for any company domain. If the logo isn’t in our database yet, you get a clean monogram fallback while our AI pipeline discovers it in the background.

Common patterns

Lookup methods

By domain

GET /v1/stripe.com — Most reliable. Works with any company domain.

By brand name

GET /v1/name/Stripe — When you only have a company name, not a domain.

By search

GET /v1/search?q=stripe — Find domains by partial or full brand name.

What happens behind the scenes

1

Request

You request a logo by domain. No auth needed.
2

Lookup

Logoo checks storage for the requested format and variant, falling back through WebP, AVIF, PNG, JPG, SVG.
3

AI discovery

If no logo exists, a monogram is returned immediately and an AI pipeline is triggered in the background. It searches 8+ social platforms (LinkedIn, YouTube, Twitter, Facebook, Instagram, Threads, Bluesky, Slack), verifies candidates with heuristics + LLM scoring, and stores the best match.
4

Delivery

The logo is served with 24-hour cache headers. Subsequent requests get the real logo.
