# Authentication

Create a bearer token at [API Keys](https://console.lithosai.cloud/keys), and set the
`Authorization` header to `Bearer $LITHOSAI_API_KEY`, where `$LITHOSAI_API_KEY` is the
generated token.

```bash theme={null}
curl https://api.lithosai.cloud/v1/models \
  -H "Authorization: Bearer $LITHOSAI_API_KEY"
```

<Warning>
  A key is shown only at its creation.
</Warning>

A key is associated with its organization, not the user who created it.

Every key in an organization draws on the same [rate limits](/rate-limits) and the same
credit balance, so adding keys separates attribution, not budget.
