About Coding Plan X

Coding Plan X is an AI API gateway that gives access to more than 600 AI models, including Claude, GPT, Gemini and DeepSeek, through a single API key. Users can pick specific models or let an Auto-mode handle routing, and the service supports OpenAI, Anthropic and Vertex protocols as well as a web UI.

The gateway follows OpenAI standards, so existing integrations can be switched by updating the Base URL and API key without code changes. It is described as working with AI development tools such as Cursor, Claude Code, Cline, Codex, OpenCode, Gemini CLI, Qwen Code and OpenClaw. The company claims costs around 20% of official pricing, along with transparent pricing, detailed usage logs, and an intelligent pooling system intended to reduce rate limits.

The service is aimed at developers, startups and enterprise teams, with suggested uses spanning coding, customer service, content creation, data analysis, translation and education. It is operated by DeepNail Limited and offers a referral program that rewards invited friends with free tokens.
