HTTPX is a fully featured HTTP client for Python 3, which provides sync and async APIs, and support for both HTTP/1.1 and HTTP/2.
**Note**: _HTTPX should be considered in beta. We believe we've got the public API to
a stable point now, but would strongly recommend pinning your dependencies to the `0.15.*`
release, so that you're able to properly review [API changes between package updates](https://github.com/encode/httpx/blob/master/CHANGELOG.md). A 1.0 release is expected to be issued sometime in late 2020._
---
Let's get started...
```pycon
>>> import httpx
>>> r = httpx.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 async API...
_Use [IPython](https://ipython.readthedocs.io/en/stable/) or Python 3.8+ with `python -m asyncio` to try this code interactively._
```pycon
>>> import httpx
>>> async with httpx.AsyncClient() as client:
>>> r = await client.get('https://www.example.org/')
>>> r
<Response [200 OK]>
```
## Features
HTTPX builds on the well-established usability of `requests`, and gives you:
* A broadly [requests-compatible API](https://www.python-httpx.org/compatibility/).
* Standard synchronous interface, but with [async support if you need it](https://www.python-httpx.org/async/).
* HTTP/1.1 [and HTTP/2 support](https://www.python-httpx.org/http2/).
* Ability to make requests directly to [WSGI applications](https://www.python-httpx.org/advanced/#calling-into-python-web-apps) or [ASGI applications](https://www.python-httpx.org/async/#calling-into-python-web-apps).
* Strict timeouts everywhere.
* Fully type annotated.
* 100% test coverage.
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
## Installation
Install with pip:
```shell
$ pip install httpx
```
Or, to include the optional HTTP/2 support, use:
```shell
$ pip install httpx[http2]
```
HTTPX requires Python 3.6+.
## Documentation
Project documentation is available at [https://www.python-httpx.org/](https://www.python-httpx.org/).
For a run-through of all the basics, head over to the [QuickStart](https://www.python-httpx.org/quickstart/).
For more advanced topics, see the [Advanced Usage](https://www.python-httpx.org/advanced/) section, the [async support](https://www.python-httpx.org/async/) section, or the [HTTP/2](https://www.python-httpx.org/http2/) section.
The [Developer Interface](https://www.python-httpx.org/api/) provides a comprehensive API reference.

## Dependencies
The HTTPX project relies on these excellent libraries:
* `httpcore` - The underlying transport implementation for `httpx`.
* `h11` - HTTP/1.1 support.
* `h2` - HTTP/2 support. *(Optional)*
* `certifi` - SSL certificates.
* `rfc3986` - URL parsing & normalization.
* `idna` - Internationalized domain name support.
* `sniffio` - Async library autodetection.
* `brotlipy` - Decoding for "brotli" compressed responses. *(Optional)*
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.
