Authentication

All API requests require a GateCtr API key.

Get your API key

Sign in at gatectr.com
Go to Settings → API Keys
Click Create key
Copy and store it securely — it won't be shown again

Use your API key

Pass it as a Bearer token in the Authorization header:

Authorization: Bearer gct_live_xxxxxxxxxxxx

Or via the SDK:

typescript const client = new GateCtr({ apiKey: process.env.GATECTR_API_KEY });

```python client = GateCtr(api_key=os.environ["GATECTR_API_KEY"])


## Key format

| Prefix | Environment |
|---|---|
| `gct_live_` | Production |
| `gct_test_` | Test (no real LLM calls) |

## Security

- Never commit API keys to source control
- Use environment variables: `GATECTR_API_KEY`
- Rotate keys in **Settings → API Keys** if compromised
- Your underlying LLM provider keys are AES-encrypted at rest — GateCtr never exposes them
