Cheap Claude Opus 5 API
Claude is what serious teams reach for when the code actually has to work. It holds a whole project in context, doesn't lose track of files ten steps into an agent run, and rarely breaks what was already working. Not the fastest model out there — but it tends to get things right the first time, which is why it's the default in Claude Code and Cursor for the hard stuff. Through cheapai it's available via an OpenAI-compatible API from $0.66/1M per 1M tokens. No VPN, pay in ₽, USDT or by card, and it works out of the box with Cursor, Claude Code, Cline and any OpenAI SDK.
