# Anthropic Multi-Environment Setup ## Overview Configure isolated Claude API environments with per-env API keys, model selection, and spend controls using Anthropic Workspaces. ## Environment Configuration ```python # config.py import os from dataclasses import dataclass @dataclass class ClaudeConfig: api_key: str model: str max_tokens: int max_retries: int timeout: float monthly_budget_usd: float CONFIGS = { "development": ClaudeConfig( api_key=os.environ["ANTHROPIC_API_KEY_DEV"], model="claude-haiku-4-20250514", # Cheap for dev max_tokens=256, max_retries=1, timeout=15.0, monthly_budget_usd=10.0, ), "staging": ClaudeConfig( api_key=os.environ["ANTHROPIC_API_KEY_STAGING"], model="claude-sonnet-4-20250514", max_tokens=1024, max_retries=2, timeout=30.0, monthly_budget_usd=50.0, ), "production": ClaudeConfig( api_key=os.environ["ANTHROPIC_API_KEY_PROD"], model="claude-sonnet-4-20250514", max_tokens=4096, max_retries=5, timeout=120.0, monthly_budget_usd=5000.0, ), } def get_config() -> ClaudeConfig: env = os.getenv("APP_ENV", "development") return CONFIGS[env] ``` ## Anthropic Workspaces (Key Isolation) Create separate Workspaces in [console.anthropic.com](https://console.anthropic.com/settings/workspaces): | Workspace | Purpose | Rate Limit Tier | |-----------|----...
