plano/config/test_passthrough.yaml

# Test configuration for passthrough_auth feature
# This config demonstrates forwarding client's Authorization header to upstream
# instead of using a configured access_key.
#
# Use case: Deploying Plano in front of LiteLLM, OpenRouter, or other LLM proxies
# that manage their own API key validation.
#
# To test:
#   pip install planoai
#   planoai up config/test_passthrough.yaml
#
#   curl http://localhost:10000/v1/chat/completions \
#     -H "Authorization: Bearer sk-your-virtual-key" \
#     -H "Content-Type: application/json" \
#     -d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "Hello"}]}'
