🚀 Nexus API is an affordable API service for working with AI models through Claude Code, Codex, OpenAI/ChatGPT-compatible clients, and Anthropic/Claude-compatible clients. The main advantage of Nexus is a balance in rubles, low request costs, a convenient Telegram dashboard, and fast integration of new models. You top up your Nexus API balance, and API keys are created independently in the Telegram dashboard.
