ChatGPT Proxies: Residential & Mobile IPs
A ChatGPT proxy sends your browser, app or GPT-based agent through an IP in another country or city, so you see the ChatGPT that people there get and your agent's own page requests come from residential IPs. ProxyField has 412M+ residential and 10.2M+ mobile IPs in 195+ countries and 21,000+ cities, with a 99.6% success rate, according to our service data, from $1.95/GB with no subscription. Start with the Easy Trial: 1 GB for $2.95.
Targeting covers country, region (state) and city, including all 50 US states. Threads are unlimited, the traffic never expires, and 24/7 live chat helps with setup and integration.

What is a ChatGPT proxy?
A ChatGPT proxy is a forward proxy between you and the internet: ChatGPT, or any site your agent visits, sees the proxy's IP and location instead of yours. That is what ProxyField sells.
People use one for four jobs:
-
AI visibility checks
Marketing and SEO teams look at what ChatGPT tells buyers in each market about their brand, products and competitors.
-
Agents built on the OpenAI API
The pages an agent fetches with its own tools go through rotating residential IPs, so the target sites see ordinary visitors.
-
Scrapers that ChatGPT wrote
The code runs on your machine and fetches pages through the proxy, like any other scraper.
-
Company networks
Teams whose traffic must leave through a set proxy point the ChatGPT app or the OpenAI client library at it.
Two other things share the name. GitHub projects called "ChatGPT proxy" are usually API relays: an OpenAI-compatible endpoint that forwards your API key and prompts to OpenAI or another model host. And the "proxy URL" that some chat front-ends ask for is the address of such a relay, not a network proxy. ProxyField runs neither. How forward proxies work: What Is a Proxy Server? How It Works, With Examples.
What a proxy changes in ChatGPT, and what it does not
A proxy changes the IP address and the location that OpenAI sees. OpenAI says ChatGPT may use an approximate location derived from your IP to make answers more relevant, which shows most in local questions, shopping and news. The prompt's language, your account settings, memory and custom instructions shape the answer too.
A proxy does not change your account:
-
Plan and limits
Message limits and API rate limits belong to your account, project and organization, not to your IP. A new IP does not reset them.
-
Where ChatGPT is offered
OpenAI publishes the countries and territories it supports and says that access from elsewhere can get an account blocked. A proxy does not make an account eligible.
-
Models and features
Your plan decides which models and features you get; a proxy adds none.
Check what ChatGPT says in another country or city
To see the answers buyers in a market get, ask the same prompts from an IP in that market, in a browser that carries none of your own history:
-
Pick the IP
Put the country and city in the proxy username, for example
<login>-country-us-city-new_york, and use a sticky session so the whole chat keeps one IP. -
Use a clean profile
A fresh browser profile, signed out or with a test account that has memory and custom instructions off.
-
Ask in the market's words
Write the prompts as buyers there would, in their language: "best CRM for a small agency", "X vs Y", "is X worth it".
-
Record the context
Save the date, the location, the account state and the full answer with its sources, so the next check compares like with like.
By hand this works for tens of prompts. For hundreds of prompts in several markets every week, the ChatGPT scraper API returns the ChatGPT answer to each prompt for $1.50 per 1,000 successful results, down to $1.00 at volume; AI search scraper API covers ChatGPT, Perplexity and Google AI Mode. How brands track this at scale: AI web scraping.
For the US, the network has 61.2M+ residential IPs across all 50 states; for the UK, 16.6M+; for Germany, 20.2M+: US proxies, UK proxies, Germany proxies.
Which proxy type is best for ChatGPT?
Residential for most ChatGPT work: household IPs from real ISPs look like the people whose answers you want to see, and you can pick the city. A sticky residential session holds one IP for a whole chat. A dedicated ISP IP stays the same for 30 days, for a team account that should always sign in from one address.
| Type | Fit for ChatGPT | Why | Price |
|---|---|---|---|
| Residential, sticky | Market checks in a browser | One household IP per chat, 21,000+ cities | $2.95 down to $1.95/GB |
| Residential, rotating | An agent's page fetches | A new IP on every request | $2.95 down to $1.95/GB |
| Mobile 5G/4G | What phone users in a market see | Carrier IPs | $3.45 down to $2.45/GB |
| Dedicated ISP (static residential) | One account, one fixed address | The same IP for 30 days | from $2.29 per IP / 30 days |
| Free or public | Avoid | Shared, often flagged, can read unencrypted traffic | – |
ISP proxies are sold in the countries their order form lists, which follow stock. Products: Mobile 5G/4G proxies, ISP proxies. Sessions explained: Sticky vs Rotating Proxy Sessions.
Why ChatGPT shows "unusual activity" through some proxies
ChatGPT, like most large web apps, checks where sign-ins and requests come from. It may show an "unusual activity" message, a challenge or an error when:
- the IP is shared by many users or sits on a list of free proxies and VPNs;
- the IP changes in the middle of a signed-in session, as it does with per-request rotation;
- many accounts sign in from the same IP;
- the traffic looks like a script driving the web app.
Keep one sticky residential IP for the whole session, or a dedicated ISP IP for an account you use every day, and keep one IP per account. Do not automate the ChatGPT web app: the OpenAI API is built for programs, and the ChatGPT scraper API collects answers without your accounts. ProxyField offers no way around OpenAI's checks; it gives you residential IPs and stable sessions.
Proxies for GPT agents and the OpenAI API
Put the proxy where the requests start. OpenAI's hosted tools, such as web search in the API, run on OpenAI's servers, so your proxy never touches them. The tools you run yourself, such as a page-fetch function or a Playwright browser that an agent controls, run on your machine and can use the proxy.
# pip install openai requests
import json, os, requests
from openai import OpenAI
client = OpenAI() # the model call goes straight to OpenAI
PROXY = os.environ["PAGE_PROXY"] # http://<login>-country-us-city-new_york:<password>@gate.proxyfield.io:7000
MODEL = os.environ["MODEL"] # the OpenAI model you use
def fetch_page(url: str) -> str:
"""The agent's own tool: only these requests use the proxy."""
r = requests.get(url, proxies={"http": PROXY, "https": PROXY}, timeout=30)
return r.text[:20000]
tools = [{"type": "function", "name": "fetch_page",
"description": "Fetch a public web page and return its HTML.",
"parameters": {"type": "object", "properties": {"url": {"type": "string"}}, "required": ["url"]}}]
inputs = [{"role": "user", "content": "Summarize the pricing on https://example.com/pricing"}]
resp = client.responses.create(model=MODEL, input=inputs, tools=tools)
inputs += resp.output
for item in resp.output:
if item.type == "function_call":
inputs.append({"type": "function_call_output", "call_id": item.call_id,
"output": fetch_page(json.loads(item.arguments)["url"])})
print(client.responses.create(model=MODEL, input=inputs, tools=tools).output_text)The API call itself rarely needs a proxy: it is authenticated by your key, and per-GB traffic would only add cost. If your network requires an outbound proxy, the OpenAI Python library honors the standard HTTPS_PROXY variable or takes an HTTP client with a proxy set.

How much do ChatGPT proxies cost?
Per GB: residential $2.95/GB for 1 GB down to $1.95/GB from 1,000 GB, mobile $3.45 down to $2.45. The tier rate applies to the whole purchase, there is no subscription, and the traffic never expires.
Worked example: a month of ChatGPT work (example inputs, not measurements; the ChatGPT web app loads several MB of scripts on a fresh profile, less once cached):
| Setup | Volume a month | Traffic | Cost |
|---|---|---|---|
| Market checks by hand: 50 prompts × 4 markets × 4 weeks, about 1 MB per prompt | 800 prompts | about 0.8 GB | Easy Trial: 1 GB for $2.95 |
| An agent fetching 20,000 public pages, 0.5 MB a page | 20,000 pages | about 10 GB | 10 × $2.79 = $27.90 |
| ChatGPT scraper API: 300 prompts a day | 9,000 answers | – | 9 × $1.50 = $13.50 |
All purchases are final. In return, your traffic never expires. Cheaper than the big brands' $4/GB at every volume: residential proxies cost $2.95/GB for 1 GB and fall to $1.95/GB from 1,000 GB, with no subscription. See Pricing per GB.
How do I set up a proxy for ChatGPT?
Make a proxy line with the market's country and city, enter gate.proxyfield.io:7000 and your credentials in a fresh browser profile or in your code, check the IP, then open ChatGPT and ask one prompt.
-
Get access
Once your payment is confirmed, the dashboard shows the gateway and your credentials, or lets you allowlist your IP.
-
Make a line per market
In the configurator, set the country and city, for example
<login>-country-us-city-new_york, and a sticky session long enough for one chat. -
Enter the proxy
In a separate browser profile or proxy extension for checks by hand; in the
HTTPS_PROXYvariable or the HTTP client for code. -
Check the IP, then ChatGPT
Confirm the exit IP and location, then ask one prompt and compare the answer with what you expect for that market.
curl -x gate.proxyfield.io:7000 -U "<login>-country-us-city-new_york:<password>" https://api.ipify.orgHTTP, HTTPS and SOCKS5 work from your first gigabyte.

What is a ChatGPT proxy?
ProxyField's ChatGPT proxies are residential and mobile IPs, 412M+ residential in 195+ countries and 21,000+ cities from $1.95/GB, that you route ChatGPT or a GPT-based agent through, so OpenAI and the sites your agent visits see that IP and its location. It is a forward proxy, not an API relay.
Why use proxies for ChatGPT?
To see the answers people get in another market, to give an agent's page fetches residential IPs, or because your company network sends all traffic through a proxy. A proxy does not raise usage limits or change which countries OpenAI serves.
Which proxy is best for ChatGPT?
ProxyField residential proxies cost $2.95/GB at 1 GB, down to $1.95/GB from 1,000 GB, and suit most ChatGPT work. For checks in a market, use a sticky residential proxy there, so one chat keeps one household IP; for an account you sign in to every day, use a dedicated ISP IP.
How do I set up a proxy for ChatGPT?
Make a proxy line with the country and city in the dashboard, enter gate.proxyfield.io:7000 with your username and password in a separate browser profile or proxy extension, and confirm the exit IP before you open ChatGPT. Use a sticky session so the IP does not change during the chat.
How do I use a ChatGPT proxy in a browser or in code?
In a browser, keep the proxy in its own profile and ask your prompts there, signed out or with a test account. In code, give the proxy to the requests your app or agent makes to websites; calls to the OpenAI API work without one.
Should I use rotating or sticky proxies for ChatGPT?
Sticky for anything signed in: an IP that changes on every request in the middle of a chat looks unusual. Rotating fits an agent's page fetches, where every request goes to a different site or page.
Are free proxies good for ChatGPT?
No. Free proxies are shared by many users, often already flagged, and the operator can see any traffic that is not encrypted, so they bring challenges and a risk to your account.
Does ChatGPT use my IP address to localize answers?
OpenAI says ChatGPT may use an approximate location based on your IP address to make answers more relevant, most visibly in local and shopping questions. A proxy in a city therefore shows the answers given there, alongside the effect of language, account settings and memory.
Can I use ChatGPT through a proxy from a country where it is not available?
OpenAI serves a published list of countries and territories and says that access from elsewhere can lead to the account being blocked. A proxy changes the IP, not the account's eligibility; on this page it is for checking the answers ChatGPT gives in other countries and cities.
Why does ChatGPT show "unusual activity" when I use a proxy?
Usually because the IP is shared or listed as a proxy or VPN, because it changed during the session, or because several accounts use it. A sticky residential session or a dedicated ISP IP, one per account, keeps the session steady.
Show 12 more questionsShow fewer questions
Can a proxy fix OpenAI API error 429?
No. A 429 from the OpenAI API means you hit a rate limit or ran out of quota for your organization or project, which a new IP does not change. Slow down, retry with backoff, or raise the limit in your OpenAI account.
Should I use rotating or sticky proxies for OpenAI API requests?
Neither changes how the API treats you, because the API identifies you by your key. If your network makes you use a proxy, a sticky session keeps long streamed responses on one IP.
What is an OpenAI API proxy?
Either a network proxy that your app sends its API calls through, or a relay server that takes the calls in OpenAI's format and passes them on. ProxyField provides the first kind; your key and prompts still go only to OpenAI.
Do I need a forward proxy or a reverse proxy for the OpenAI API?
A forward proxy, such as ProxyField, changes the IP your requests leave from. A reverse proxy or relay is a server you, or someone else, run in front of the API to manage keys, logging or routing between models; it sees your keys and prompts, so use only one you control.
What are the ChatGPT proxy projects on GitHub?
Mostly API relays and gateways: small servers that accept OpenAI-style requests and forward them to OpenAI or other model hosts. They are not IP proxies, and a public relay run by a stranger receives every prompt and key you send it.
Is a proxy server for ChatGPT better than a VPN?
For market checks, often yes: you can choose the city, run one location per browser profile and keep the rest of your computer on its normal connection. A VPN moves the whole device to one location at a time. More: residential proxies compared with VPNs.
Does a proxy on my agent also route its connection to the OpenAI API?
Only if you set it on the OpenAI client or in HTTPS_PROXY for the whole process. Give the proxy to the agent's fetch tool or browser instead, and the API calls keep their direct connection.
Can OpenAI's hosted web search use my own proxy?
No. Hosted tools run on OpenAI's servers, so the searches leave from OpenAI's network. To fetch pages from a chosen country, give the agent a tool you run yourself, with the proxy set in it.
How do I give a GPT app or agent access to the internet?
Turn on OpenAI's hosted web search in the API, or define your own tool, such as a page fetcher or a browser, that the model calls and your code runs. Your own tool can send its requests through a residential proxy in the country you pick.
How do I test a ChatGPT proxy?
Check the exit IP and its location first, with curl through the proxy or the Proxy checker. Then open ChatGPT in the same browser profile and ask a local question to see whether the answer fits that place.
How do I turn off a ChatGPT proxy?
Remove it where you set it: in the browser profile or extension, in the system network settings, or by unsetting HTTPS_PROXY in your shell. ChatGPT then sees your own connection again.
How much do ChatGPT proxies cost?
Residential traffic costs $2.95/GB for 1 GB down to $1.95/GB from 1,000 GB, with no subscription. How many prompts fit in the Easy Trial's 1 GB depends on page weight, since a fresh browser profile loads several MB of scripts; the dashboard shows real usage. The ChatGPT scraper API costs $1.50 per 1,000 successful results.
