Learn how to bypass restrictions and stream responses using the curl_cffi library in g4f.
curl_cffi
library to enable bypassing restrictions and streaming responses from various providers. This document explains how curl_cffi
works under the hood and how we utilize it in g4f to enhance the functionality.
curl_cffi
is a Python library that provides a convenient interface to the libcurl C library. It allows making HTTP requests with advanced options and fine-grained control over the request and response handling.
Key Features of curl_cffi
curl_cffi
uses the libcurl C library to perform the actual HTTP requests. It provides a Pythonic interface to interact with libcurl, abstracting away the low-level details.
Step 1: Initialize Session

’s capabilities to bypass certain restrictions imposed by providers. Here’s how it works:
Bypassing Cloudflare
curl_cffi
along with a headless browser (e.g., Selenium) to solve the Cloudflare challenge and obtain the necessary cookies and headers to make successful requests.Impersonating Browsers
curl_cffi
allows setting custom user agent strings and headers to disguise the requests as originating from a browser.curl_cffi
’s streaming capabilities to handle responses that are delivered in chunks. This is particularly useful for providers that support streaming, as it allows processing the response data incrementally without waiting for the entire response to be received.
StreamResponse
and StreamSession
classes in G4F wrap the curl_cffi
response and session objects, respectively, to provide a convenient interface for handling streaming responses.curl_cffi
, G4F is able to bypass restrictions, impersonate browsers, and handle streaming responses efficiently. This enables seamless integration with various providers and enhances the overall functionality of the library.
