What it does

CoderPlan is a usage-billed API entry point for developers who work with coding tools such as Claude Code, Cursor, Codex CLI and Gemini CLI. One endpoint serves Claude, GPT and Gemini models and works with clients built for the OpenAI or Anthropic protocols. The site says it connects directly to official models and charges no monthly fee and no quota windows. You register, create an API key and point your tool at a single base URL. Each request is billed by tokens, and the account keeps a record of the model, tokens, cache savings and cost for every call. Repeated context is charged at a lower cache-read price, which the site gives as the main reason its prices can stay low. Credit is prepaid in top-up tiers and does not expire. The price table is in yuan per million tokens and covers 39 models. The site says it only handles access and usage records and does not store code or conversation text. Most of the page is in Chinese, with an English version linked.
