## Sign up and sign in

- New users create an account on the [sign-up page](https://app.nexinfer.com/sign-up?lang=en).
- Existing users can use a username or email on the [sign-in page](https://app.nexinfer.com/sign-in?lang=en).
- Password reset and email verification options depend on what the dashboard currently exposes.

## Create a key

After signing in, open **API Keys**, create a key, and save the complete value. Copy it directly into a system secret manager or environment variable.

Confirm three settings before using the key:

1. its group and allowed models;
2. its remaining quota or usage limit;
3. whether each client or environment should have a separate key.

Do not share one key across teams, production, and testing. Disable and rotate a key immediately after exposure or when a team member leaves.

## Verify the key

```bash
curl https://api.nexinfer.com/v1/models \
  -H "Authorization: Bearer $NEXINFER_API_KEY"
```

A `200` response confirms authentication. The returned list is the authoritative model scope for that key.
