* fix(vertex_ai): improve passthrough endpoint url parsing and construction (#17402)
* test(proxy): add test for vertex passthrough load balancing
Add a test that verifies _base_vertex_proxy_route uses
get_available_deployment for proper load balancing instead of
get_model_list. This ensures the correct deployment is selected
from the router and vertex credentials are properly fetched.
Also refactor the implementation to:
- Use get_available_deployment instead of get_model_list
- Add error handling for deployment retrieval
- Improve code structure with try-except block
* feat(proxy): add pass-through deployment filtering methods
Add dedicated methods to filter and select deployments for pass-through endpoints:
- Implement get_available_deployment_for_pass_through() to ensure only deployments with use_in_pass_through=True are considered
- Implement async_get_available_deployment_for_pass_through() for async operations
- Add _filter_pass_through_deployments() helper method to filter by use_in_pass_through flag
- Update vertex pass-through route to use the new dedicated method
This ensures pass-through endpoints respect the use_in_pass_through configuration and apply proper load balancing strategy only to configured deployments.
Add comprehensive tests to verify filtering and load balancing behavior.
Fixes#17477
Guardrails couldn't access request headers (like User-Agent) on Bedrock
pass-through endpoints because headers were only stored in
data["proxy_server_request"]["headers"] but not in data["metadata"]["headers"]
where guardrails typically look for them.
This fix adds headers to metadata in add_litellm_data_to_request() so
guardrails can access User-Agent, API keys, and other header-based checks
on all endpoints including Bedrock pass-through.
Test added to verify headers are available in metadata for guardrails.
extract model id from vertex ai passthrough routes that follow the pattern:
/vertex_ai/*/models/{model_id}:*
the model extraction now handles vertex ai routes by regex matching the model
segment from the url path, which allows proper model identification for
authentication and authorization in proxy pass-through endpoints.
adds comprehensive test coverage for vertex ai model extraction including:
- various vertex api versions (v1, v1beta1)
- different locations (us-central1, asia-southeast1)
- model names with special suffixes (gemini-1.5-pro, gemini-2.0-flash)
- precedence verification (request body model over url)
- non-vertex route isolation

* fix(passthrough): pass custom_llm_provider to completion_cost for Azure AI Anthropic
The passthrough logging for Anthropic was failing when using Azure AI Anthropic
because the completion_cost function was not receiving the custom_llm_provider
parameter, causing it to fail with "LLM Provider NOT provided" error.
This fix:
- Retrieves custom_llm_provider from logging_obj.model_call_details
- Prepends provider prefix to model name for cost calculation
- Passes both formatted model and custom_llm_provider to completion_cost
- Centralizes provider prefix logic in _create_anthropic_response_logging_payload
This ensures cost calculation works correctly for Azure AI Anthropic requests
with models like azure_ai/claude-sonnet-4-5_gb_20250929.
