One fixed server IP for your API calls — in a country OpenAI supports, and the same address every time.
OpenAI serves its API only in the countries on its supported list. Mainland China, Hong Kong, Macau and Russia are not on it: a request from an unsupported location gets 403 “Country, region, or territory not supported”, and OpenAI warns that access from outside the list may get an account blocked or suspended.
In code, the fix is small. The official Python and Node SDKs both accept a proxy, so only the client you configure sends its API traffic through it, while the rest of the machine stays on its normal network.
A fixed datacenter IP suits calls from scripts and servers: it’s the lowest price per IP, and it stays the same for the whole term. That gives you one fixed address for your project’s IP allowlist — with the allowlist on, OpenAI rejects requests from any other address, even with a valid key.

| Item | Datacenter IP | Static ISP IP |
|---|---|---|
| What you get | A server IP, fixed for the term | A home-broadband IP, fixed for the term |
| Price | US$3.99 for 30 days | US$7.99 for 30 days |
| Best for | API calls from scripts, servers and agents | A person signing in to ChatGPT in a browser |
| IP allowlist | One fixed address to add | One fixed address to add |
Prices per IP in US dollars, the same in every country; the wallet uses PTC at 1 PTC = US$1. If the same person also uses ChatGPT in a browser, the ChatGPT setup starts from static ISP.

| Item | Choose | Why |
|---|---|---|
| Product | Datacenter proxy, per IP | A fixed server address at the lowest price per IP |
| Country | One on OpenAI’s supported list, e.g. the US, Japan or Singapore | The order page shows which countries are in stock |
| Protocol | HTTP | The examples below use an HTTP proxy URL; the IP keeps the protocol you buy it with |
| How many IPs | One per server or environment | Each environment keeps its own address on the allowlist |
| Term | Renew before the end date | Auto-renewal isn’t available yet; renewing keeps the same IP, so the allowlist entry stays valid |
The button below opens datacenter proxies with the AI setup; Protocol starts on HTTP and Term on 30 days. Pick the country and Quantity (up to 100 at a time) before you pay.
The button below opens datacenter proxies with the AI setup. Pick a country on OpenAI’s supported list, keep Protocol on HTTP and Term on 30 days, set Quantity to one IP per server or environment, then click Review cost and generate.
In My assets, View credentials shows host, port, username and password; Copy all copies them in one go.
Run the three commands below on the machine that will make the calls. The first must show the country you bought; the second should print 401 before you add a key.
Expected result The third command returns your list of models.
Before continuing From mainland China the proxy usually can’t be reached directly: on Windows or macOS run the Proxy302 Helper (Connect → Helper tools) and use its local address and port in place of HOST:PORT.
Use the Python or Node example below. Only the client you configure uses the proxy; other programs on the machine keep their normal network.
On platform.openai.com open Settings → Security → IP allowlist, add the exit IP the first command showed and enable the allowlist for the project. Changes take up to 15 minutes; calls from other addresses then fail with 401 ip_not_authorized.
Before continuing Add every environment that calls the API — CI, staging, your own laptop — before you enable it, or those calls stop.

# 1) Exit IP and country of your datacenter IP (HTTP line)
curl -x "http://USERNAME:PASSWORD@HOST:PORT" https://ipinfo.io/json
# 2) Does OpenAI accept this exit? Without a key, 401 = yes, 403 = unsupported country
curl -s -o /dev/null -w "%{http_code}\n" -x "http://USERNAME:PASSWORD@HOST:PORT" \
https://api.openai.com/v1/models
# 3) With your key: 200 and the list of models
curl -x "http://USERNAME:PASSWORD@HOST:PORT" https://api.openai.com/v1/models \
-H "Authorization: Bearer $OPENAI_API_KEY"A 401 without a key means the request reached OpenAI from a supported location; a 403 “Country, region, or territory not supported” means the exit isn’t in a supported country. The third call only lists models, so it’s a safe first test of the key.

}As in the OpenAI Node SDK’s proxy instructions: undici’s ProxyAgent as the dispatcher, paired with undici’s own fetch. The username and password in the proxy URL are sent as proxy authentication.
Check Does ipinfo.io through the same proxy show a supported country, and does your client actually use the proxy?
Fix Pass the proxy to the client that calls the API, as in the examples, and use an IP in a supported country.
Check Is the exit IP on the allowlist that applies to this key? A project allowlist replaces the organization’s.
Fix Add the exit IP to that allowlist, wait up to 15 minutes and test again.
Check Is a character missing from the username or password, or has the IP’s term ended?
Fix Copy the details again from My assets and check the end date.
Check Does the machine have the operating system’s CA certificates? HTTPX2 no longer uses certifi.
Fix Install the CA certificates, or set SSL_CERT_FILE to a CA bundle.
Check How fast is your job sending requests?
Fix Pace the requests and follow the Retry-After header.
Not from there directly: they aren’t on OpenAI’s supported list, and the API answers 403. A proxy changes your network exit, not OpenAI’s terms — OpenAI warns that access from outside its supported countries may get an account blocked or suspended.
Datacenter for calls from code: a fixed server address at US$3.99 for 30 days. Choose static ISP, US$7.99 for 30 days, when a person signs in to ChatGPT in a browser.
Yes. The IP stays the same for the term, so you can add it under Settings → Security → IP allowlist. An allowlist holds up to 50 addresses or ranges, and other addresses are then rejected even with a valid key.
HTTP is simplest: both SDK examples take an HTTP proxy URL. The Python SDK also works with SOCKS5 once httpx2[socks] is installed. Buy the IP with the protocol you’ll use — each IP keeps one.
No. In the examples only the OpenAI client goes through the proxy; your browser and other programs keep their normal network.
