# LinkAGI Model API

**APIs profiled:** 5

LinkAGI is a Chinese third-party AI API relay (中转站) that fronts a pool of upstream model accounts behind a single host, api.linktoagi.com, and re-exposes them on three imitated vendor protocols: OpenAI-compatible Chat Completions and Responses, an Anthropic Messages-shaped route, and a Gemini generateContent-shaped route. It is sold to developers running Codex, Claude Code, Gemini CLI and desktop chat clients who want a CNY, prepaid, pay-as-you-go base-URL swap instead of a foreign card and a vendor account. A token belongs to a group (号池) that decides which models it can address and at what billing ratio; the live model and price table is published unauthenticated at /api/pricing. The service runs the open-source New API gateway and publishes a first-party OpenAPI 3.1, APIs.json, llms.txt and Postman collection, plus an unusually candid evidence boundary that marks its Anthropic and Gemini compatibility as advertised but unverified.
