Residential, ISP or Datacenter: Which Proxy an AI Agent Needs

The three proxy types in plain words

Rotating residential: traffic leaves through IP addresses that internet providers assigned to ordinary homes and mobile users. The address changes, per request or over time, depending on how the service is set up, so requests spread over many addresses. You usually choose a country, and sometimes a state or city. It is billed by the gigabyte.

Static ISP: an IP address registered to an internet provider that stays fixed for the whole lease, which runs from one day to several months. The same address is used on every sign-in until the lease ends. It is billed per IP and lease term.

Datacenter: an IP address from a block owned by a hosting or cloud company. It is fixed for the lease, usually the cheapest of the three and quick to respond, but the hosting origin is easy to recognize, and some websites treat such addresses differently from home or ISP addresses.

Match the proxy to the agent's task

The same agent platform can do very different jobs. Pick the proxy for the job, not for the platform. Four common agent tasks follow.

Research and browsing agents

An agent that reads public pages from many countries, for example to check local search results, compare regional prices or follow news, fits rotating residential. Each request can leave from a different address, and you pick the country per request or per session. Traffic is billed by the gigabyte, so the page count matters more than the number of IPs.

If you need the same page seen from several places, see the guide to checking prices in other countries.

Agents that sign in to one account

An agent that signs in to a store back office, a social account or an AI subscription is better served by one fixed address than by a rotating one: the account is used from the same network address on every run. A static ISP IP is built for this, and it is billed per IP and lease term, not by traffic.

For AI subscriptions, Proxy302 sells a separate product: the ISP for AI subscriptions, one static ISP IP for one subscription account, 30 days per order, in three tiers (Claude, GPT / Grok, Gemini). A proxy does not change the provider's terms; automating a signed-in account is still governed by them.

Agents that only call APIs

An agent that only calls LLM or SaaS APIs from a server usually needs no proxy at all: the request goes straight from its host to the API. A proxy matters only when your network requires one for outbound traffic, or when you need a fixed outbound address that a partner can allow-list; a datacenter IP or a static IP fits that routing job.

Each AI provider's API has its own list of supported countries, and a proxy does not change it. OpenAI, for example, states that using its services from outside the listed countries "may result in your account being blocked or suspended". Check the list for the provider you call first.

Data-collection pipelines for retrieval

A pipeline that gathers public web pages to feed a retrieval system (RAG) is the most traffic-heavy of the four, and the traffic is spread over many different sites. Rotating residential fits it, because the bill follows the gigabytes the pipeline really transfers and it can run from many locations. Whatever the proxy, check each site's terms and robots.txt before you collect.

Cost models: per GB or per IP and lease term

Rotating residential is billed per GB. A quick estimate: the HTTP Archive Web Almanac 2025 reports a median home page of 2.86 MB on desktop and 2.56 MB on mobile, and median inner pages of 2 MB on desktop and 1.8 MB on mobile. As assumptions for an example, take 100 pages per run at 3 MB each, and one run a day for 30 days: 100 x 3 MB = 300 MB per run, about 9 GB a month (1 GB = 1,000 MB). On the Budget line at US$1.50 per GB, 9 GB is US$13.50; on the Premium line at US$5 per GB, it is US$45. Real pages vary a lot, so measure a sample week before you scale.

Static ISP and datacenter leases are priced per IP and lease term: a static ISP IP is US$0.50 for 1 day and US$7.99 for 30 days, a datacenter IP US$0.25 and US$3.99. That price is for the address, so it fits an agent that keeps one account on one IP. If an agent signs in to one account and also moves a lot of data, static ISP is also sold by traffic at US$3.50 per GB (Fixed ISP exit).

Protocols: HTTP or SOCKS5

HTTP proxies work with almost every agent tool. SOCKS5 can carry other kinds of traffic, but not every tool accepts it: Claude Code, for example, states that it does not support SOCKS proxies. Python's requests library needs an extra install for SOCKS (pip install 'requests[socks]'). Playwright accepts both http:// and socks5:// in the server field, but its username and password options apply only to HTTP proxies, so use an HTTP proxy when you need credentials.

On Proxy302 every product can be bought as HTTP or SOCKS5, chosen per IP when you buy it. If a tool takes only HTTP, buy HTTP.

Playwright with an HTTP proxy and credentials

import { chromium } from 'playwright';

const browser = await chromium.launch({
  proxy: {
    server: 'http://proxy-host:port',
    username: 'USERNAME',
    password: 'PASSWORD',
  },
});
const page = await browser.newPage();
await page.goto('https://ipinfo.io/json');
console.log(await page.textContent('body'));
await browser.close();

Example only: replace the placeholder values with your own. The username and password fields work with HTTP proxies.

When an agent needs no proxy

A proxy only controls which network address a service sees. If your agent runs in a cloud environment with normal outbound internet access, calls APIs in countries the provider supports, and reads sites that load fine from that address, a proxy adds cost and one more thing to break. Add one when a task really needs a different location or a fixed address, not by default.

Measured exits: Claude from seven countries

Hourly check of the Proxy302 probe, 3 November 2026, 18:18 UTC: one request to Claude per country through a rotating residential exit, using the public Proxy302 entry. Only the first three octets of an IP are public. One sample per country, not an average; later checks will differ.

Letting the agent get its own proxy

If your agent is an MCP client such as Claude Code, Codex or Cursor, it can ask for a ready rotating residential proxy URL through proxy302-mcp. proxy302-mcp is the official Proxy302 MCP server, open source on GitHub and maintained by the Proxy302 team. Proxy302 also runs it at https://proxy302.com/v1/mcp: clients that can send an Authorization header, such as Claude Code, Cursor and VS Code, connect with an API key and install nothing. For a browser agent, the Browser Use guide shows where the proxy goes.

How to do it with Proxy302

Pick the product from the agent's task: rotating residential for research and data collection, a static ISP IP for an agent that keeps one account, the ISP for AI subscriptions for ChatGPT, Claude, Gemini or Grok accounts, a datacenter IP for plain routing.

• static ISP

How to do it with Proxy302: steps

1. Step 1

   Open the page for your product, choose the country, the traffic or the term and quantity, and for per-IP products the protocol, HTTP or SOCKS5. The protocol is fixed for each IP when you buy it.

2. Step 2

   Generate the proxy, then open My assets (the console page that holds everything you bought) and copy HOST, PORT, USERNAME and PASSWORD. The Connect page shows a ready example with your own endpoint.

3. Step 3

   Enter the details in the agent's browser, HTTP client or environment variables.

4. Step 4

   Check the exit with https://ipinfo.io/json through the proxy. The country field should match the country you chose.

5. Step 5

   From mainland China, open the Helper from the Connect page, click 「一键加速」 (One-click boost) and keep it open while you use the proxy.
