## `POST /v1/pdf/security/remove`

## Attributes

<Note>Attributes are case-sensitive and should be inside JSON for POST request. for example: `{ "url": "https://example.com/file1.pdf" }`</Note>

| Attribute                     | Type    | Required | Default | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                             |

## `Example` Response

<Note>To see the main response codes, please refer to the [Response Codes](/api-reference/response-codes) page.</Note>

```json theme={null}

  "credits": 21
}
```

<Note>
  **Inconsistent URL Encoding in cURL Output:** When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (`&`) may appear as `\u0026` in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you're parsing the response programmatically, your JSON parser will handle this conversion automatically.
