# Block Agent Signup

> Block and disable an agent-provisioned API key.

Blocks a pending agent signup, immediately disabling the API key and banning the sandboxed account. Use this if the agent created a key without authorization. No authentication required — the verification token acts as proof.

## Headers

| Header         | Value              |
| -------------- | ------------------ |
| `Content-Type` | `application/json` |

## Request Body

| Parameter            | Type   | Required | Description                                              |
| -------------------- | ------ | -------- | -------------------------------------------------------- |
| `agent_signup_token` | string | **Yes**  | The verification token from the confirmation email link. |

## Response

| Field     | Type    | Description                   |
| --------- | ------- | ----------------------------- |
| `success` | boolean | Whether the block succeeded   |
| `message` | string  | Human-readable result message |

### Example Request

```bash theme={null}
curl -X POST "https://api.firecrawl.dev/v2/agent-signup/block" \
  -H "Content-Type: application/json" \
  -d '{
    "agent_signup_token": "a1b2c3d4..."
  }'
```

### Example Response

```json theme={null}
{
  "success": true,
  "message": "Agent key has been blocked and disabled."
}
```

## What Happens on Block

* The agent's API key is **deleted**.
* The sandboxed team is **banned**.
* The sponsor record is marked as `"blocked"`, preventing future agent signups for that email.
* Any further API requests using the blocked key will return `403`.
