LangChain · PROXY SETUP

LangChain proxy setup

LLM application framework — its loaders fetch the open web. Point it at the Eveses residential pool with the configuration below — the geo lives in the username, so nothing else in your setup has to change to move country.

Watch out

LangChain's document loaders each hold their own HTTP client, so there is no single place to set a proxy. `WebBaseLoader` takes `requests_kwargs`; `AsyncHtmlLoader` does not, and needs the session passed in.

Configuration

from langchain_community.document_loaders import WebBaseLoader

proxy = "http://eveses_user_country-us:[email protected]:12321"

loader = WebBaseLoader(
    "https://target-site.com",
    requests_kwargs={"proxies": {"http": proxy, "https": proxy}, "timeout": 30},
)
docs = loader.load()

Notes for LangChain

Give each agent run its own `_session-…` token if you need the same exit IP for a multi-step task.

Tool calls that hit an API rather than a page usually do not need the proxy — route only the web loaders.

The geo and the session live in the username, not in the host or the port. Every configuration on this page stays exactly as it is when you move country — you edit one string. 199 countries are addressable, with city and state tokens inside most of them.

FAQ

How do I set a proxy in LangChain?›
Point it at proxy.eveses.com on port 12321 for HTTP, or 32325 for SOCKS5, and authenticate with your Eveses proxy username and password. The exact syntax is in the snippet above. LangChain's document loaders each hold their own HTTP client, so there is no single place to set a proxy. `WebBaseLoader` takes `requests_kwargs`; `AsyncHtmlLoader` does not, and needs the session passed in.
How do I choose the country LangChain exits from?›
Append a geo token to the USERNAME rather than changing the host: eveses_user_country-de reaches Germany, eveses_user_country-us the United States. 199 countries are addressable this way, and city or state tokens narrow it further. Nothing else in your LangChain configuration changes.
How do I keep the same IP across requests in LangChain?›
Add a session token — eveses_user_country-us_session-ab12cd34_lifetime-30m — and every request carrying that username exits from the same address until the lifetime runs out. Drop the token and each request rotates to a fresh IP.
What does this cost?›
Residential traffic is billed by the gigabyte from your Eveses wallet: $7.35/GB at 1 GB, falling to $2.57/GB in volume. There is no per-tool charge, and the same credentials work in every tool at once.
