ClaudeAPI is a third-party relay that forwards traffic to Anthropic's Claude models — it is NOT the official Anthropic API. The service supports both Anthropic and OpenAI request formats with pay-as-you-go pricing in CNY at roughly 80% of official rates (e.g. Opus $4 input / $20 output vs official $5 / $25). Models include Claude Opus 4.7 / 4.6 / 4.5, Sonnet 4.6 / 4.5 and Haiku 4.5. Claims 99.8% uptime, sub-200ms latency and zero data retention. Gateway endpoint: gw.claudeapi.com.
