 ## Essential Transformations
 
-### 1. URL Construction
-- **Vertex AI**: Regional endpoints (`us-central1-aiplatform.googleapis.com` vs `europe-west1-aiplatform.googleapis.com`)
-- **Bedrock**: Region-specific (`bedrock-runtime.{region}.amazonaws.com`)
-- **AssemblyAI**: EU vs US (`api.assemblyai.com` vs `api.eu.assemblyai.com`)
-
-### 2. Auth Header Replacement
-
-| Provider | LiteLLM Key → Provider Credential |
-|----------|-----------------------------------|
-| Vertex AI | `Bearer sk-litellm-*` → `Bearer ya29.oauth-token` |
-| Anthropic | `Bearer sk-litellm-*` → `x-api-key: sk-ant-*` |
-| Bedrock | `Bearer sk-litellm-*` → AWS SigV4 signed headers |
-| Gemini | `Bearer sk-litellm-*` → `?key={api_key}` (query param) |
-
-### 3. Logging (Optional)
-- Parse provider-native response to extract usage
-- Calculate cost using LiteLLM pricing
-- Send to callbacks (Langfuse, etc.)
+- **URL Construction** - Build correct provider URL (e.g., regional endpoints for Vertex AI, Bedrock)
+- **Auth Header Replacement** - Swap LiteLLM virtual key for actual provider credentials
+- **Logging** (optional) - Parse response to extract usage and calculate cost
 
 ## What Does NOT Change
-- Request body passes through unchanged
-- Response body passes through unchanged
-- Provider-specific parameters work as documented
