## Log AI Gateway request metadata without storing payloads

[AI Gateway](https://developers.cloudflare.com/ai-gateway/)

AI Gateway now supports the `cf-aig-collect-log-payload` header, which controls whether request and response bodies are stored in logs. By default, this header is set to `true` and payloads are stored alongside metadata. Set this header to `false` to skip payload storage while still logging metadata such as token counts, model, provider, status code, cost, and duration.

This is useful when you need usage metrics but do not want to persist sensitive prompt or response data.

```bash
curl https://gateway.ai.cloudflare.com/v1/$ACCOUNT_ID/$GATEWAY_ID/openai/chat/completions \
  --header "Authorization: Bearer $TOKEN" \
  --header 'Content-Type: application/json' \
  --header 'cf-aig-collect-log-payload: false' \
  --data '{
    "model": "gpt-4o-mini",
    "messages": [
      {
        "role": "user",
        "content": "What is the email address and phone number of user123?"
      }
    ]
  }'
```
