Built for the products that show companies

Fintech & broker apps

Company marks next to tickers, holdings, and watchlists without a logo vendor contract.

CRM & outreach

Avatars for every inbound domain. Initials when a mark does not exist — no console 404 storm.

News & research

Publisher cards, congress trades, ETF holdings — the same logos Eulerpool ships on-site.

AI agents

Agents that render companies need a mark URL. This is it. Pair with the Eulerpool data API.

Logo API FAQ

Yes. The hotlink https://eulerpool.com/api/logo/{domain} needs no API key and has no monthly request cap. Authenticated calls to /api/1/logo also do not consume your financial-data quota. Fair-use abuse (scraping our origin as a CDN for unrelated traffic) can be blocked; normal product use is the point of the product.

logo.dev is a paid logo vendor: free commercial use requires attribution, the Community plan hard-caps at 500,000 requests/month, and Pro is $150/month. Eulerpool gives you the same domain/ticker/ISIN/name/crypto lookups with no key, no cap, and no attribution.

Not for domain logos. Paste the URL. Sign up only if you want ticker, ISIN, name, or crypto lookups on api.eulerpool.com — and that key also unlocks 100,000 free financial-data calls/month.

PNG, WebP, and JPG. Optional size (16–300), retina, and greyscale on the authenticated API. The hotlink defaults to a sharp 128px retina WebP.

The API returns 404 so your UI can show initials. Add ?quiet=1 on eulerpool.com to receive a 1×1 transparent GIF instead — useful in lists of unknown domains.

Never pay for logo data again

Hotlink now. Or take a free data-API key and look up by ticker, ISIN, name, and crypto on the same stack.
