BUZZ provides a Claude API proxy service that forwards requests unchanged to Anthropic's Claude models. It supports Claude Opus 4.6, Sonnet 4.6, and Haiku 4.5 models with transparent request/response handling—no model substitution, context trimming, or hidden prompts. The service features multi-node redundancy for availability, native Prompt Cache support for Claude Code sessions, and pay-as-you-go pricing with no monthly fees or subscriptions. Pricing is per million tokens: Opus 4.6 input ¥0.7220, output ¥2.8880; Sonnet 4.6 input ¥0.1444, output ¥0.5776; Haiku 4.5 input ¥0.0361, output ¥0.1805. Integration involves changing the base URL in SDKs like Anthropic or OpenAI, with a one-click script for Claude Code users. Use cases include AI development, content generation, and data processing via Claude's capabilities.
