# Authentication

> Authenticating requests with your API key.

Every request is authenticated with an API key, passed as a bearer token:

```bash theme={null}
curl "https://api.enrichloop.com/v1/companies/enrich" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain":"stripe.com"}'
```

Generate and manage API keys from your dashboard under **Settings → API Keys**.

A request with a missing or invalid key gets back `401 Unauthorized`.
