# Data Guardrails & UU PDP

> Automated PII redaction and compliance with Indonesian Personal Data Protection law (UU PDP No. 27/2022).

Neosantara includes built-in automated data privacy guardrails designed for Indonesian regulatory compliance (UU PDP No. 27/2022). The gateway scans and redacts sensitive Personally Identifiable Information (PII) before forwarding prompts to upstream model providers.

## Per-Request Header Activation

Data guardrails are available exclusively to **paid users** (paid subscription tier or accounts with an active PAYG balance). The feature operates as an opt-in control per request using the `X-Guard` header:

<CodeGroup>
  ```python Python icon="python" theme={"theme":{"light":"ayu-dark","dark":"catppuccin-latte"}}
  from openai import OpenAI
  import os

  client = OpenAI(
      base_url="https://api.neosantara.xyz/v1",
      api_key=os.environ["NEOSANTARA_API_KEY"],
      default_headers={"X-Guard": "on"}
  )

  response = client.chat.completions.create(
      model="deepseek-v4.1-flash",
      messages=[
          {"role": "user", "content": "The customer KTP number is 3201234567890001 and bank account is 1234567890."}
      ]
  )
  print(response.choices[0].message.content)
  ```

  ```bash cURL icon="terminal" theme={"theme":{"light":"ayu-dark","dark":"catppuccin-latte"}}
  curl -X POST "https://api.neosantara.xyz/v1/chat/completions" \
    -H "Authorization: Bearer $NEOSANTARA_API_KEY" \
    -H "X-Guard: on" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "deepseek-v4.1-flash",
      "messages": [
        {"role": "user", "content": "My KTP number is 3201234567890001."}
      ]
    }'
  ```
</CodeGroup>

## Supported Header Values

The `X-Guard` header accepts the following values:

| Header Value       | Status   | Description                                               |
| :----------------- | :------- | :-------------------------------------------------------- |
| `X-Guard: on`      | Active   | Enables automated PII redaction for the specific request. |
| `X-Guard: enabled` | Active   | Synonym for `on` for integration convenience.             |
| `X-Guard: off`     | Disabled | Bypasses inspection (default when the header is omitted). |

<Warning>
  **Security & Activation Policies**:

  1. **Paid Users Only**: Requests on the Free tier do not activate payload redaction even if the `X-Guard` header is passed.
  2. **Explicit Header Required**: Account database preferences do not auto-enable provider payload redaction. Every request requiring inspection must explicitly pass `X-Guard: on` or `X-Guard: enabled`.
</Warning>

## Redacted Data Categories

Inspection uses contextual patterns tuned to Indonesian legal documents and data formats:

| Category               | Targeted Entity       | Typical Pattern                           | Redacted Output              |
| :--------------------- | :-------------------- | :---------------------------------------- | :--------------------------- |
| **Official Identity**  | NIK / KTP Number      | 16-digit structured national identifier   | `[REDACTED_NIK]`             |
| **Tax & Legal**        | NPWP                  | 15 or 16-digit tax registry format        | `[REDACTED_NPWP]`            |
| **Travel Documents**   | Indonesian Passport   | Official Indonesian passport format       | `[REDACTED_PASSPORT]`        |
| **Driver Licenses**    | SIM                   | National driver license format            | `[REDACTED_DRIVING_LICENSE]` |
| **Telecommunications** | Indonesian Phone      | Prefixes `+62`, `62`, `08` (10-13 digits) | `[REDACTED_PHONE]`           |
| **Correspondence**     | Email Address         | Standard RFC 5322 email patterns          | `[REDACTED_EMAIL]`           |
| **Banking**            | National Bank Account | Indonesian bank account numbers           | `[REDACTED_BANK_ACCOUNT]`    |
| **Transactions**       | Credit / Debit Card   | 16-digit Luhn algorithm patterns          | `[REDACTED_CREDIT_CARD]`     |
