Clarification on Using ANTHROPIC_BASE_URL for Custom Models and Adapters

I am seeking clarification regarding Anthropic's Commercial Terms of Service and Usage Policy.

Specifically, is it permissible under Anthropic's ToS to:

1. Use the ANTHROPIC_BASE_URL environment variable (as documented here: https://docs.anthropic.com/en/docs/claude-code/llm-gateway) to route SDK/API requests to custom models or endpoints that are not Anthropic's official models?
2. Publish adapters or code on GitHub that enables others to use ANTHROPIC_BASE_URL to connect to non-Anthropic models or endpoints?

Are there any restrictions or implications under Anthropic's Terms of Service for these activities?

Thank you for clarifying whether this usage is compliant with Anthropic's policies.
