Quickstart

Your first company profile in five minutes.

You need an account and a terminal. At the end, you have fetched the company profile of Hetzner Online GmbH with an example request, and you know what the response contains.

Copy your API key

Create a free account and confirm your email address. You get 150 start credits, valid for 30 days.

Your first API key is already waiting for you under Account › API keys. Copy it and treat it like a password.

Every request sends the key in the x-api-key header. The examples use YOUR_API_KEY as a stand-in for it.

If the API responds with 401, the key is missing or was not copied completely. With 403, your email address is not confirmed yet. You find the confirmation link in your inbox.

Fetch a company profile

Call fetch-organization and pass the company name in the parameter q. Without further parameters, you get the basic data for 5 credits.

Copy the request, insert your key and run it. cURL prints the JSON directly. In Python and JavaScript, the response is then in data. With print(data["name"]) or console.log(data.name) you see the company name.

curl -G "https://handelsregister.ai/api/v1/fetch-organization" \
  -H "x-api-key: YOUR_API_KEY" \
  --data-urlencode 'q=Hetzner Online GmbH'

import requests

response = requests.get(
    "https://handelsregister.ai/api/v1/fetch-organization",
    headers={"x-api-key": "YOUR_API_KEY"},
    params={
        "q": "Hetzner Online GmbH",
    },
)
data = response.json()

const url = new URL("https://handelsregister.ai/api/v1/fetch-organization");
url.searchParams.append("q", "Hetzner Online GmbH");

const response = await fetch(url, {
  headers: { "x-api-key": "YOUR_API_KEY" },
});
const data = await response.json();
