Knowledge base

Step-by-step guides for connecting to the OneForProxy gateway, targeting exit IPs, troubleshooting errors and managing billing. Looking for the full reference instead? See the Docs.

Getting started

Create an account, generate a proxy credential, and send your first request through the gateway.

Integration

curl, Python and Node.js

Working proxy examples for curl, Python (requests and aiohttp) and Node.js (undici and axios), plus how to handle proxy errors in each.

Browser extensions (FoxyProxy, SwitchyOmega)

Configure FoxyProxy or SwitchyOmega with HTTP or SOCKS5, select a country through the username, and keep one IP with a sticky session.

Using proxies in multi-profile browser tools

Fill in the standard proxy fields of any multi-profile or fingerprint-isolated browser tool, and give each profile its own sticky session.

Management API

Drive your whole account programmatically with an API key — credentials, IP whitelist, usage, CSV exports, wallet and monthly plans.

Targeting

Targeting (country, state, city, ASN)

The full username DSL for targeting a country, state, city or carrier ASN, with formatting rules and examples.

Sticky sessions

The difference between rotating and sticky IPs, how -session- and -life- work, and when to use each.

Troubleshooting

Errors

Every HTTP status and SOCKS5 reply code the gateway returns, what each one means, and what to do about it.

Billing

Billing and packages

How USDT-TRC20 top-ups work, monthly plans and prepaid traffic packages vs. pay-as-you-go, renewals and cancellation, settlement timing, and checking your balance from the API.
