# Zero Data Retention

> Contractual guarantee: the model provider stores neither request nor response. Three activation levels with a verified-endpoints registry.

ZDR is a contractual guarantee from the model provider: the request and response **are not stored in any form** (logs, telemetry, cache, fine-tuning). Geek Hub maintains a list of endpoints where this guarantee is signed and verified, and **rejects ZDR-marked requests targeting endpoints outside the list**.

## Three activation levels

<Steps>
  <Step title="Per request">
    Pass `zdr: true` in your body. The gateway checks the target model against the registry. Verified → proceed. Not verified → HTTP 422 with reason.
  </Step>

  <Step title="Per account">
    In `/dashboard/settings → Zero Data Retention` enable ZDR per provider group (Anthropic, OpenAI, Google, Others). When a group is on, all org requests to that group are checked.
  </Step>

  <Step title="Per guardrail">
    [Guardrails](/en/features/guardrails) let you configure ZDR per user or per API key. Useful when different teams under the same org need different policies.
  </Step>
</Steps>

## Example request

```bash theme={null}
curl -X POST https://api.geekhub.mx/v1/chat/completions \
  -H "Authorization: Bearer ghub_sk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "anthropic/claude-sonnet-4-6",
    "messages": [{"role":"user","content":"Hi"}],
    "zdr": true
  }'
```

## Rejection format

```json theme={null}
{
  "error": {
    "type": "zdr_not_verified",
    "message": "Provider does not offer a signed ZDR policy verified by Geek Hub.",
    "model": "deepseek/deepseek-chat",
    "verified_alternatives": ["openai/gpt-5", "anthropic/claude-sonnet-4-6"]
  }
}
```

## GDPR — art. 5(1)(e) data minimization

ZDR is part of your GDPR **art. 5(1)(e)** (storage limitation) compliance posture. If your provider doesn't retain the conversation, retention at that layer is effectively zero — reducing the scope of your upstream processing obligations.

<Note>
  ZDR covers the **model provider's** retention. Geek Hub does store billing metadata (model id, tokens, cost, latency) for CFDI/Stripe. Message **content** is not persisted at the gateway layer.
