Overview

Client for Claude Platform on Google Cloud — the first-party Anthropic API served through the Google Cloud gateway.

This is distinct from VertexClient, which targets the :rawPredict publisher-model API (publisher model IDs, messages only). This client speaks the full first-party Anthropic API: requests pass through the gateway unchanged — standard /v1/* paths, standard model names, the complete API surface. The deprecated text Completions endpoint is intentionally not exposed.

Creates a new client for the Anthropic API on the Google Cloud gateway.


Authentication uses Google credentials by precedence (unless
skip_auth is true):


1. `token_provider` — a callable returning a GCP access token, called
 per attempt
2. `google_credentials` — a `googleauth` credentials object (anything
 responding to `#apply`), refreshed by the library as needed
3. Application Default Credentials (`Google::Auth.get_application_default`)
 with the `cloud-platform` scope


  





  
Parameters:


    
  
    
  • 
      
        project
      
      
        (String, nil)
      
      
        (defaults to: ENV["ANTHROPIC_GOOGLE_CLOUD_PROJECT"] || ENV["GOOGLE_CLOUD_PROJECT"])
      
      
        —
        
    GCP consumer project id. Defaults to
ENV["ANTHROPIC_GOOGLE_CLOUD_PROJECT"], then
ENV["GOOGLE_CLOUD_PROJECT"], then the project reported by the
resolved Google credentials. Only required when the base URL must be
derived.
    
      
    
    • 
  
    
  • 
      
        location

        (defaults to: ENV["ANTHROPIC_GOOGLE_CLOUD_LOCATION"] || "global")
      
      
        —
        
    GCP location. Defaults to
ENV["ANTHROPIC_GOOGLE_CLOUD_LOCATION"], then "global"; an
explicit nil falls back to the same defaults.
    
      
    
    • 
  
    
  • 
      
        workspace_id

        —
        
    Defaults to
ENV["ANTHROPIC_GOOGLE_CLOUD_WORKSPACE_ID"]. Required unless
skip_auth is true and an explicit base_url is given.
    
      
    
    • 
  
    
  • 
      
        base_url
      
      
        (String, nil)
      
      
        (defaults to: ENV["ANTHROPIC_GOOGLE_CLOUD_BASE_URL"])
      
      
        —
        
    Override the gateway base URL. Defaults to
ENV["ANTHROPIC_GOOGLE_CLOUD_BASE_URL"], otherwise derived from
project, location, and workspace_id via URL_TEMPLATE.
    
      
    
    • 
  
    
  • 
      
        google_credentials

        (defaults to: nil)
      
      
        —
        
    A googleauth-compatible
credentials object. Mutually exclusive with skip_auth.
    
      
    
    • 
  
    
  • 
      
        token_provider

        (defaults to: nil)
      
      
        —
        
    A callable returning a GCP access
token string. Takes precedence over google_credentials. Mutually
exclusive with skip_auth.

        skip_auth
      
      
        (Boolean)
      
      
        (defaults to: false)
      
      
        —
        
    When true, no token is attached and
workspace_id is only required when the base URL must be derived.
For callers fronting with their own authenticated proxy. Mutually
exclusive with token_provider and google_credentials.
