Proxy Servers for ChatGPT and OpenAI API

Because the challenge fires on your IP address, not your account — you're seeing Cloudflare's verdict on the reputation of the address you're connecting from. Shared VPN exits and flagged ranges are the classic trigger: hundreds of strangers have already used that IP today, and if enough of them looked like bots, everyone behind it gets the loop. Some users pass the checkbox only to land right back on it, indefinitely.

A dedicated ChatGPT proxy ends this in the least dramatic way possible: you become the only person writing that IP's history. After a few days of normal use there's nothing on the address for Cloudflare to object to, and the challenges stop appearing.

In Python, pass a pre-configured HTTP client:

import httpx
from openai import OpenAI

client = OpenAI(
    http_client=httpx.Client(
        proxy="http://login:password@IP:port"
    )
)

The lower-effort alternative works for most stacks without touching code: set the HTTPS_PROXY environment variable, and the Python SDK, most Node.js HTTP libraries, and cURL will pick it up automatically. In Node's native fetch, pass an Undici ProxyAgent as the dispatcher. Whichever route you choose, every request to api.openai.com then exits from your proxy's address — which is exactly the point.

Connecting through a proxy is not, by itself, a violation — plenty of corporate networks route all traffic through one, and OpenAI can't and doesn't prohibit that. What OpenAI's terms do prohibit is circumventing its geographic restrictions: using any tool to access the service from a country it doesn't serve. That distinction is worth taking seriously, because the account you'd risk may have months of chat history and paid API credits attached.

The legitimate pattern — and the one this page is built around — is stabilization within supported geography: one address in a supported country, used consistently, so your account stops inheriting flags from shared exits and misclassified cloud IPs.

Depends on which of the two surfaces you're using. The chatgpt.com website sits behind Cloudflare's reputation scoring, where a consumer-classified ISP address has a visibly easier life — that's why it's our default recommendation for accounts you log into daily. The API is a different animal: an OpenAI API proxy mostly needs to get geography right, and datacenter addresses in supported countries handle API traffic routinely. If your workload is API-only — pipelines, agents, batch jobs — a datacenter package from $19/mo does the job at a fraction of the price; reserve the ISP plan for the browser side.

Send a request through the exact same route your OpenAI traffic takes — same proxy, same environment — to an IP echo service, then look that address up in several third-party geolocation databases. Several, because they disagree — the Google Cloud Seoul outage happened precisely because one database read those IPs as Hong Kong while others said South Korea, and you don't know which source OpenAI weighs. If the databases split on your IP's country, treat it as a risk. This is also the fastest pre-purchase test: take a trial IP, run the lookup, and confirm the classification before you build anything on top of it.
