Logo CDN

<img src="https://logo.prefetch.io/stripe.com?token=pk_YOUR_TOKEN" alt="Stripe" width="64" height="64" />

The logo CDN serves any domain’s logo as an image, from Cloudflare’s network. Use it wherever you show companies, such as customer lists, transaction feeds, CRM records and search results, without storing a single image yourself.

No credits. Logo requests don’t touch your credit balance: each plan includes a monthly quota of them.
Embeddable. The token is a publishable token: it serves logo images and nothing else, so it is safe in your HTML. It is not your API key.
Always an image. A domain whose logo isn’t known yet gets a letter mark in a stable color, and its logo is looked up in the background. The next request usually has it.

Your token

Get it from the API with your API key:

curl "https://api.prefetch.io/logo/token" -H "X-API-Key: $PREFETCH_API_KEY"

{
  "success": true,
  "data": {
    "token": "pk_4f1c9e2b7a0d4c3e8b6a1f2d3c4b5a69",
    "cdn_url": "https://logo.prefetch.io",
    "example": "https://logo.prefetch.io/stripe.com?token=pk_4f1c9e2b7a0d4c3e8b6a1f2d3c4b5a69",
    "quota": 100000,
    "used": 1234,
    "period": "2026-10-01"
  }
}

There’s one token per organization, and it stays the same when you rotate API keys, so logos already on your pages keep working. If someone else is using your token against your quota, rotate it. Every logo embedded with the old token stops loading at once.

Parameters

https://logo.prefetch.io/<domain>?token=<token>[&size=128][&format=png][&theme=light][&greyscale=true][&fallback=monogram]

Parameter	Default	Values
`<domain>`	required	Any domain: `stripe.com`, `www.stripe.com` and `https://stripe.com/pricing` all mean `stripe.com`.
`token`	required	Your publishable token.
`size`	`128`	16–512 pixels. Logos are square, centred on a transparent background.
`format`	`png`	`png`, `webp` or `jpeg` (`jpg` works too).
`theme`	`light`	The background a JPEG is flattened onto (`light` is white, `dark` near-black). PNG and WebP stay transparent.
`greyscale`	`false`	`true` for a grey logo.
`fallback`	`monogram`	What a domain without a known logo gets: `monogram` (the letter mark), `404`, or `transparent` (an empty image).

Unknown values fall back to the default instead of failing, because a broken image helps nobody.

Examples

<img src="https://logo.prefetch.io/linear.app?token=pk_YOUR_TOKEN&size=48" width="24" height="24" alt="Linear" />

function CompanyLogo({ domain, size = 32 }) {
  return (
    <img
      src={`https://logo.prefetch.io/${domain}?token=${process.env.NEXT_PUBLIC_PREFETCH_LOGO_TOKEN}&size=${size * 2}`}
      width={size}
      height={size}
      alt=""
      loading="lazy"
      style={{ borderRadius: 6 }}
    />
  );
}

![Stripe](https://logo.prefetch.io/stripe.com?token=pk_YOUR_TOKEN&size=64)

Request twice the size you display for sharp logos on high-density screens. The letter mark is a square; round it with CSS if you want a circle.

Where logos come from

In order: Prefetch’s curated brand data; the icons the site declares for itself (its apple touch icon, icons and web app manifest), largest first; and, when those are all tiny, the logo in the page itself. The result is stored once and every size and format is cut from it. Logos are cached at the edge for a week.

Quotas

Plan	Logo requests per month
Free	100,000
Starter	250,000
Pro	1,000,000
Growth	3,000,000
Scale	10,000,000
Enterprise	Unlimited

Months are calendar months (UTC), and the count resets on the 1st. Only images served count. An invalid token, a quota refusal or a fallback=404 doesn’t count, and browsers cache each logo for a day, so repeat views are free. Past the quota, requests get 429 until the 1st or until you upgrade.

Errors

Status	When
`400`	The path is not a domain.
`401`	No token, or not a valid one (a rotated token, for example).
`429`	Your organization’s monthly logo quota is used up.

Errors are JSON with an error message. The logo CDN is not available through RapidAPI.
