API Reference

Free Logo API

A free, open REST API for 77,838+ company logos. No key, no auth, no rate limits — just hotlink an image or pull the catalog as JSON. Powered by Crustdata.

Introduction

Every company has a stable id (slug). Use it to embed a logo image directly, or query the JSON endpoint to search and filter the whole catalog. Responses are CORS-enabled, so you can call it straight from the browser.

Free to use. Please keep a link back to crustdata.com. For a logo removal request, email info@crustdata.com.

Quick start

Embed any logo with a single image tag — no install, no key:

html

<img src="https://tools.crustdata.com/freelogoapi/api/logo/stripe" alt="Stripe logo" height="48" />

Or fetch the catalog as JSON:

bash

curl "https://tools.crustdata.com/freelogoapi/api?search=stripe&limit=5"
