Zero Data Retention - Wafer

Require Zero Data Retention (ZDR) for individual Wafer Serverless requests.

Require ZDR

Serverless requests do not require ZDR by default unless your account is configured to require it. Add this header to require ZDR:

Wafer-ZDR: required

curl -sS "https://pass.wafer.ai/v1/chat/completions" \
  -H "Authorization: Bearer <YOUR_WAFER_API_KEY>" \
  -H "Wafer-ZDR: required" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "GLM-5.3",
    "messages": [
      {"role": "user", "content": "Hello!"}
    ],
    "max_tokens": 128
  }'

Model support

Check GET https://pass.wafer.ai/v1/models. Models that support ZDR advertise zdr_supported: true. If the selected model does not support ZDR, a ZDR-required request is rejected with HTTP 422 and code model_zdr_not_supported.

Account requirements

Some accounts require ZDR for every request. Those accounts do not need to send the header. Sending it remains valid and does not change the account requirement.
