# Authentication

Authenticate with an API key sent in the `apikey` header. Find your key in the
[dashboard](https://savvyiq.ai/api-keys).

```bash
curl 'https://api.savvyiq.ai/v3/entities/siq_33d67jj0wJESjEdFHMhuQ' \
  -H 'apikey: YOUR_API_KEY'
```

A missing or invalid key returns `401`. An account not yet enabled for the v3 API returns
`403 no_pricing_configured`. Contact us and we will switch it on.
