Demand for cutting‑edge AI tools has created an unusual workaround ecosystem in China: a grey market of “shadow API” relay platforms that resell access to overseas models such as Anthropic’s Claude, Google’s Gemini, and OpenAI’s ChatGPT.
These services act as intermediaries between Chinese developers and foreign AI providers whose products are blocked or unsupported in mainland China. Instead of connecting directly to OpenAI, Google, or Anthropic, developers send requests to a third‑party gateway that secretly forwards them to overseas infrastructure and returns the result. [6][

The result is an underground but increasingly visible marketplace for AI access—advertised openly on Chinese e‑commerce platforms and developer communities.
Many leading Western AI services are not officially available in mainland China. ChatGPT has never been directly accessible there, and OpenAI moved in 2024 to block API traffic originating from unsupported regions including mainland China and Hong Kong. [36]
Similarly, major providers such as Anthropic and Google restrict API access to supported regions and have tightened enforcement against entities tied to restricted jurisdictions. [17]

A fast‑growing grey market of “shadow API” relay platforms lets Chinese developers access overseas AI models like Claude, Gemini, and ChatGPT without VPNs by routing API requests through overseas proxy servers or pool... Sellers on marketplaces such as Taobao and Xianyu promote low‑latency, no‑VPN developer endpoints, discounted tokens, and OpenAI‑compatible APIs so apps can integrate foreign models despite regional restrictions.
The ecosystem persists because developers want frontier models for coding and product development—but it carries major risks including data exposure, unreliable access, and possible violations of provider terms.

This leaves developers in China with limited direct access to frontier models, even though those tools are widely used elsewhere for coding assistants, automation, and AI applications.
Shadow APIs—sometimes described in Chinese developer communities as “transfer stations”—are third‑party services that resell or relay access to foreign AI APIs. [4]
Instead of giving customers their own accounts with the original provider, these platforms provide:
When a developer sends a prompt to the relay endpoint, the platform forwards the request to an overseas server that calls the real model. The output is then sent back to the developer’s application. [6][
8]
Because the proxy infrastructure sits outside mainland China, the developer does not need to maintain a VPN connection—the bypass happens server‑side.
Most relay services rely on a combination of techniques:
In some cases, investigations have also reported riskier practices such as using stolen credentials or substituting different models behind the same API interface. [3][
4]
Listings for AI relay services appear on platforms such as Taobao and Xianyu, where vendors openly promote access to models like Claude or Gemini. [6][
8]
Typical selling points include:
Some investigations have found that certain grey‑market Claude access offers tokens at around 10% of official pricing, reflecting the use of pooled infrastructure or other cost‑cutting methods. [3][
4]
Despite the risks, many developers use relay services for practical reasons.
Access to frontier models is the biggest factor. Tools such as Claude and Gemini remain among the most capable models for coding, reasoning, and automation tasks, and developers want them for product development and benchmarking. [6][
8]
Lower costs are another draw. Grey‑market providers often advertise steeply discounted tokens or pay‑as‑you‑go access that appeals to small teams and independent developers. [3]
Finally, there is a workflow advantage: a stable API endpoint inside China is easier to integrate into applications, developer tools, and CI pipelines than managing VPNs, foreign payment methods, and overseas accounts.
The same features that make shadow APIs convenient also introduce serious risks.
First, data security is uncertain. Because the relay operator handles every request, prompts, code, and outputs may be logged or stored. Some reports warn that prompts and outputs may even be harvested for resale as AI training data. [3]
Second, service reliability can disappear overnight. If upstream providers suspend the proxy’s accounts or block traffic from a specific network, the relay service can fail immediately. [8]
Third, developers cannot always verify that the advertised model is actually being used. Some relays may quietly substitute cheaper models while presenting an OpenAI‑compatible API. [3]
The shadow API ecosystem reflects a broader dynamic in global AI access: restrictions from providers and governments create incentives for intermediaries to build technical workarounds.
As providers tighten enforcement and detection, relay operators adapt with new proxy networks, infrastructure, or account pools. The result is a continuing cat‑and‑mouse cycle—driven largely by developer demand for the most capable AI models available anywhere in the world. [2][
