A next-generation HTTP client for Python.

HTTPX2 is a fully featured HTTP client library for Python. It includes an integrated command line client, has support for both HTTP/1.1 and HTTP/2, and provides both sync and async APIs.

Install HTTPX2 using pip:

Now, let's get started:

>>> import httpx2
>>> r = httpx2.get('https://www.example.org/')
>>> r
<Response [200 OK]>
>>> r.status_code
200
>>> r.headers['content-type']
'text/html; charset=UTF-8'
>>> r.text
'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'

Or, using the command-line client.

pip install 'httpx2[cli]'  # The command line client is an optional dependency.

Which now allows us to use HTTPX2 directly from the command-line:

HTTPX2 builds on the well-established usability of requests, and gives you:

Plus all the standard features of requests...

• International Domains and URLs
• Keep-Alive & Connection Pooling
• Sessions with Cookie Persistence
• Browser-style SSL Verification
• Basic/Digest Authentication
• Elegant Key/Value Cookies
• Automatic Decompression
• Automatic Content Decoding
• Unicode Response Bodies
• Multipart File Uploads
• HTTP(S) Proxy Support
• Connection Timeouts
• Streaming Downloads
• .netrc Support
• Chunked Requests

Install with pip:

Or, to include the optional HTTP/2 support, use:

pip install httpx2[http2]

Project documentation is available at https://httpx2.pydantic.dev/.

For a run-through of all the basics, head over to the QuickStart.

For more advanced topics, see the Advanced Usage section, the async support section, or the HTTP/2 section.

The Developer Interface provides a comprehensive API reference.

Install Logfire with HTTPX instrumentation support:

pip install 'logfire[httpx]'

HTTPX2 works out of the box with Pydantic Logfire, our observability platform built on OpenTelemetry. One line instruments every request, giving you traces, timings, and status codes with no other changes:

import logfire
import httpx2

logfire.configure()
logfire.instrument_httpx()

httpx2.get("https://pydantic.dev/")

This works the same way for explicit httpx2.Client() and httpx2.AsyncClient() instances, and you can scope instrumentation to a single client by passing it in: logfire.instrument_httpx(client). Pass capture_all=True to also record headers and bodies. See the Logfire HTTPX docs for the full set of options.

If you want to contribute with HTTPX2 check out the Contributing Guide to learn how to start.

The HTTPX2 project relies on these excellent libraries:

• httpcore2 - The underlying transport implementation for httpx2.
• anyio - Structured concurrency primitives, used to support both asyncio and trio.
• truststore - SSL verification using the operating system's trust store.
• idna - Internationalized domain name support.

As well as these optional installs:

• h2 - HTTP/2 support. (Optional, with httpx2[http2])
• socksio - SOCKS proxy support. (Optional, with httpx2[socks])
• rich - Rich terminal support. (Optional, with httpx2[cli])
• click - Command line client support. (Optional, with httpx2[cli])
• brotli or brotlicffi - Decoding for "brotli" compressed responses. (Optional, with httpx2[brotli])
• backports.zstd - Decoding for "zstd" compressed responses on Python 3.13 and below. (Optional, with httpx2[zstd]. On Python 3.14+, zstd is supported via the stdlib compression.zstd module when it is available, and the httpx2[zstd] extra installs nothing.)

A huge amount of credit is due to requests for the API layout that much of this work follows, as well as to urllib3 for plenty of design inspiration around the lower-level networking details.
