Model Armor Direct Sanitization API Example
This example tests Model Armor's sanitization API directly using the HTTP provider.
Use this approach when you want detailed filter results or to test templates
without calling an LLM.
Prerequisites:
1. Enable Model Armor API: gcloud services enable modelarmor.googleapis.com
2. Create a template (see README.md for gcloud commands)
3. Set environment variables:
- GOOGLE_PROJECT_ID
- MODEL_ARMOR_LOCATION (default: us-central1)
- MODEL_ARMOR_TEMPLATE
- GCLOUD_ACCESS_TOKEN=$(gcloud auth print-access-token)
Run with: promptfoo eval
