# API Keys

API keys authenticate requests to the 2027.dev MCP server and API.

## Creating a key

1. Sign in to [2027.dev/evals](https://2027.dev/evals)
2. Go to **Settings** → **API Keys**
3. Click **Create Key** and give it a name
4. Copy the key immediately — it won't be shown again

API keys start with `evals_` and are tied to your organization.

## Security

* Keys are hashed before storage — we cannot recover a lost key
* Each key is scoped to your organization's data
* Keys can be revoked at any time from the Settings page

## Usage

Include the key in the `Authorization` header:

```bash theme={null}
Authorization: Bearer evals_YOUR_API_KEY
```
