"My Team Had GCP Credits. Claude Code Wanted an Anthropic Key."

Short summary

Engineer bridges Claude Code to Google Cloud by building a local API gateway (CliGate) that translates Anthropic's API protocol to Vertex AI, eliminating the need for a separate API key and billing surface. The pattern handles regional routing and works with other CLIs (Codex, Gemini). Router-based architecture lets teams swap providers later without rewiring tools.

• •CliGate local gateway consolidates Claude Code with Vertex AI, unifying credentials and billing
• •Translates Anthropic Messages API to Vertex publisher endpoints with regional model family routing
• •Extensible design supports Codex CLI and Gemini CLI without tool configuration changes
