# Zero data retention

> Restrict routing to vendors with zero data retention agreements, for the whole organization or per project and customer. Covers fail-closed errors, BYOK, and how to list eligible models.

Zero data retention (ZDR) limits routing to vendors that have agreed not to store or train on your prompts and completions. Turn it on when customer contracts or your security review require it.

## How it works

* **Routing fails closed.** Only ZDR vendors are candidates, even if your routing policy lists others. If none can serve the request, Gateway rejects it instead of falling back.
* **BYOK vendors count as compliant.** Traffic on your [vendor key](/merge-gateway/capabilities/byok/overview) runs under your agreement with that vendor.
* **The model list follows it.** `GET /v1/models` shows only ZDR routes and omits models with none.
* **The response store is off.** `store: true` retains nothing, so [conversation resumption](/merge-gateway/capabilities/multi-turn-conversations) is unavailable.
* **Web search skips Browserbase.** Every other [web search](/merge-gateway/capabilities/web-search) engine (`exa`, `youcom`, `parallel`, `interfaze`, `tavily`) qualifies; `engine: "auto"` skips `browserbase`.

ZDR governs vendors only. Keeping request and response bodies in your logs is the payload logging setting under **Settings → Organization**.

## Turn it on

Turn on **Zero data retention** under **Configure → Request settings → Routing restrictions** in the [dashboard](https://gateway.merge.dev/configuration/routing-restrictions). It applies from the next request and needs Manage organization settings.

## Scoped controls

Projects and end customers can override ZDR and [vendor and region restrictions](/merge-gateway/security/geo-location-routing). The most specific scope wins (**customer → project → organization**), and each control inherits separately. Whether a scope can relax the organization depends on how the request reaches it:

* **Pinned by the API key** (a project- or customer-scoped key): the override applies in full, on or off
* **Named on the request** (the `X-Project-Id` header, a body `project_id`, or a body `customer`): the override can only tighten; a relaxing value is ignored

Set overrides on a project's or customer's **Controls** tab or over the API. Only the dashboard, with Manage organization settings, can save an override that relaxes the organization; the API returns `403 scoped_controls_loosening_forbidden`.

**`Project`**

```bash title="Project"
# Turn ZDR on for one project (management key)
curl -X PUT https://api-gateway.merge.dev/v1/projects/$PROJECT_ID/controls \
  -H "Authorization: Bearer $MERGE_GATEWAY_MANAGEMENT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"zero_data_retention": true}'
```

**`Customer`**

```bash title="Customer"
# Turn ZDR on for one end customer (API key)
curl -X PUT https://api-gateway.merge.dev/v1/customers/$CUSTOMER_ID/controls \
  -H "Authorization: Bearer $MERGE_GATEWAY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"zero_data_retention": true}'
```

`GET` on the same path returns `override`, `effective`, and `sources` (the scope behind each value). `DELETE` clears the override.

> **The body replaces the whole override**
>
> Send only the fields to override. Omitted fields inherit the organization, `"zero_data_retention": null` stops overriding, and an empty list such as `"allowed_vendors": []` means no restriction for that scope. Unknown fields return 422.

## Check which models qualify

`GET /v1/models?zero_data_retention=true` lists models with at least one ZDR vendor, and `vendors.<slug>.zero_data_retention` marks which routes qualify. `GET /v1/vendors?zero_data_retention=true` lists ZDR vendors, flagged with `supports_zdr`.

**`cURL`**

```bash title="cURL"
curl "https://api-gateway.merge.dev/v1/models?zero_data_retention=true&limit=500" \
  -H "Authorization: Bearer $MERGE_GATEWAY_API_KEY" \
  | jq -r '.data[] | "\(.model): \([.vendors | to_entries[] | select(.value.zero_data_retention) | .key] | join(", "))"'
```

**`Python`**

```python title="Python"
import os
import requests

url = "https://api-gateway.merge.dev/v1/models"
headers = {"Authorization": f"Bearer {os.environ['MERGE_GATEWAY_API_KEY']}"}
params = {"zero_data_retention": "true", "limit": 500}

while True:
    page = requests.get(url, headers=headers, params=params).json()
    for m in page["data"]:
        zdr_vendors = [slug for slug, v in m["vendors"].items() if v["zero_data_retention"]]
        print(m["model"], zdr_vendors)
    if not page["has_more"]:
        break
    params["cursor"] = page["next_cursor"]
```

## Models with ZDR coverage

With ZDR on, each model below routes only to the vendors shown, and unlisted models are rejected. For live data, use the [model catalog](/merge-gateway/models/catalog) ZDR filter or the API calls above.

## Errors

If a request pins a model, vendor, or web search engine that doesn't meet the ZDR restriction, Gateway returns `400 invalid_request_error`. The `code` is `zdr_vendor_unavailable` for model or vendor routes, and `server_tool_zdr_unavailable` for a pinned web search engine. A policy with no eligible ZDR route returns the same error type without a code.
