Getting Started

Authentication

The API supports two authentication methods: API key and Bearer token. Both work on every endpoint.

Authentication Methods

`x-api-key: YOUR_API_KEY`	API key via header: Recommended for server-to-server integrations and production use.
`?api_key=YOUR_API_KEY`	API key via query parameter: Quick tests and backwards compatibility only — the key is visible in the URL.
`Authorization: Bearer YOUR_TOKEN`	Bearer token: Best when you need fine-grained scopes, expiry dates, or instantly revocable access.

API Key Authentication Examples

Using the x-api-key header (recommended)

curl -X GET "https://handelsregister.ai/api/v1/search-organizations?q=company" \
     -H "x-api-key: YOUR_API_KEY"

# Using query parameter (legacy)
curl "https://handelsregister.ai/api/v1/fetch-organization?api_key=YOUR_API_KEY&q=company"

# Using x-api-key header (recommended)
curl -X GET "https://handelsregister.ai/api/v1/fetch-organization?q=company" \
     -H "x-api-key: YOUR_API_KEY"

import requests

# Using x-api-key header (recommended)
url = "https://handelsregister.ai/api/v1/fetch-organization"
headers = {"x-api-key": "YOUR_API_KEY"}
params = {"q": "company"}

response = requests.get(url, headers=headers, params=params)
data = response.json()

# Using query parameter (legacy)
params_with_key = {
    "api_key": "YOUR_API_KEY",
    "q": "company"
}
response = requests.get(url, params=params_with_key)
data = response.json()

// Using x-api-key header (recommended)
const response = await fetch('https://handelsregister.ai/api/v1/fetch-organization?q=company', {
  headers: {
    'x-api-key': 'YOUR_API_KEY'
  }
});
const data = await response.json();

// Using query parameter (legacy)
const url = new URL('https://handelsregister.ai/api/v1/fetch-organization');
url.searchParams.append('api_key', 'YOUR_API_KEY');
url.searchParams.append('q', 'company');

const legacyResponse = await fetch(url);
const legacyData = await legacyResponse.json();

Managing Bearer Tokens

Create a token

curl -X POST "https://handelsregister.ai/api/v1/auth/tokens/create" \
     -H "x-api-key: YOUR_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{
       "token_name": "My Application",
       "abilities": ["*"],
       "expires_at": "2026-01-01 00:00:00"
     }'

The response includes your Bearer token — store it securely.

Use a token

curl -X GET "https://handelsregister.ai/api/v1/search-organizations?q=company" \
     -H "Authorization: Bearer YOUR_API_TOKEN"
