Brand assets API: a brand’s official logo files, by domain

LogoAPI.sh is a free brand assets API for logo files: https://logoapi.sh/search?q=stripe returns the brand’s logo and icon URLs, and for 702 brands, every version from the brand’s own kit as a direct file URL. No key, no signup.

“Brand assets” usually means the files in a company’s press kit: the main logo, the square mark, a white version for dark slides, maybe a horizontal lockup. Getting them by hand means finding the press page, downloading a zip, and picking the right file. That is fine for one brand. It does not work for an app that shows hundreds of customers, partners or integrations.

This page explains what our API returns, what it does not, and how it compares with the other services people find for this search.

Short answer

If you know the domain, you do not even need a call. These are plain file URLs:

https://logoapi.sh/stripe.com.svg        logo (wordmark when we have one)
https://logoapi.sh/icon/stripe.com.svg   square icon
https://logoapi.sh/stripe.com.png        PNG, 128 to 1024 px
https://logoapi.sh/white/stripe.com.svg  one colour: white, black or grey
https://logoapi.sh/dark/stripe.com.svg   for dark backgrounds

To list every file we have for a brand, including its official kit versions, call search. No key. No signup. No attribution. 2M requests a month per site. Free.

What you get

Kit versions are the brand’s own files, byte for byte. We never redraw a logo or rebuild it from parts. When a kit file is flagged as the primary logo, it becomes the main logo at /{domain}.svg too.

What it does not cover

Two more limits, so there are no surprises:

• Not every brand has kit versions. 702 of 5,031 brands do today. For the rest you get our checked logo, icon and the made versions above.
• No zip download. kit_url points at the brand’s own site. We mirror single files from the kit, not the whole package.

How it works

1. We read the brand’s own kit.For each brand with a public press kit or brand guidelines page, we save the logo files it publishes, with the label the brand gives them.
2. Each file is labelled.Kind (logo or icon), background (light or dark), and which file is the main one. Files with an odd label or a missing file are dropped at build time.
3. Each file gets a stable URL./v/{slug}/{domain}.svg. The file is served byte for byte, with an ETag, open CORS and the header X-Logo-Variant: official.
4. Search lists them./search?q= returns the brand with a versions array and the kit_url, so your code can pick a file by label or kind.

Brand assets APIs compared

The services that show up for “brand assets API” do different jobs. Here are the facts side by side.

LogoAPI.sh from its code and docs, Nov 4, 2026. Rival cells from their official docs and live requests, checked Nov 4, 2026.

	LogoAPI.sh	Brandfetch	Logo.dev	Simple Icons
Logo files	SVG and PNG; logo and icon	Yes; SVG for logo and symbol types	JPG, PNG, WebP on the CDN. The Brand API downloads PNG, JPG or WebP	One-colour SVG icon
Brand’s own kit files	Yes, for 702 brands, untouched	Brands can claim and edit their profile	Not in the docs	No; redrawn to one colour
Dark and one-colour	/dark/, /white/, /black/, /grey/	Light and dark themes	theme and greyscale options	Any one colour
Brand colours	Not in the API (brand pages only)	Yes, in the Brand API	Yes, in the Brand API	One hex per brand in the package
Fonts	No	Yes	No	No
Key	None	Client ID for logos; API key for the Brand API	Publishable key; secret key for the Brand API	None
Free tier	2M requests a month per site	Logo API: 1M a month, fair use. Brand API: 100 free fetches, one time	500K CDN requests a month plus $5 in API credits	Free, open source

In short: pick Brandfetch if you need the full brand profile, with colours and fonts, and can use a key. Pick LogoAPI.sh if you need the right logo file, including the brand’s own versions, with no key and no setup. Pick Simple Icons for small one-colour UI icons.

Use it in your code

Pick the brand’s white logo for a dark slide

const r = await fetch("https://logoapi.sh/search?q=resend.com");
const { results: [brand] } = await r.json();  // best match first
const white = brand.versions?.find(v => v.kind === "logo" && /white/i.test(v.label));
const src = white?.url ?? `https://logoapi.sh/dark/${brand.domain}.svg`;

If the brand has no white version in its kit, fall back to /dark/: it uses the brand’s official dark file when one exists, and a contrast rule when not. See logos for dark background.

Link to the brand’s guidelines

When you show partner logos, link kit_url in your admin UI, so your team can check the brand’s rules before a launch.
