About

eOPT helps developers connect the official Claude Code client to an API service and get started on macOS, Windows, and Linux. Developers can use Claude Code in their own projects for codebase exploration, feature development, debugging, and refactoring.

The service provides API key management, setup guides, a prepaid wallet, and request-level usage records. Input tokens, output tokens, cache reads, and cache writes are recorded separately so users can inspect how each request is billed. File access, code edits, and command execution are performed by the Claude Code client on the user’s computer.

eOPT is an independent third-party service. Pricing is based on model and token usage; current rates and setup instructions are available on the website.
