README

@cortexkit/pi-anthropic-auth

Use Claude Pro/Max subscriptions in Pi with @cortexkit/pi-anthropic-auth. The companion @cortexkit/opencode-anthropic-auth package supports OpenCode 1 and 2; both integrations use the shared @cortexkit/anthropic-auth-core package.

Why use it

  • Multiple Claude accounts with ordered fallbacks, quota-aware routing and per-session account affinity.
  • Prompt-cache controls and optional cache keepalive for active sessions.
  • Optional Claustrum integration: Claustrum is a local credential-vault service that supplies Claude accounts instead of each application's local account pool.
  • An optional user-owned Cloudflare relay to reduce repeated request uploads.

Disclaimer

This project is not affiliated with or endorsed by Anthropic. Using Claude subscriptions outside Anthropic's official clients may violate Anthropic's terms and can lead to account restrictions or suspension. Use it at your own risk.
