Introducing Niquests: A Modern Python HTTP Client with HTTP/1.1, HTTP/2, and HTTP/3 Support

Niquests is a simple and elegant HTTP client for Python, positioned as a direct replacement for the stagnant Requests library. It uniquely provides automatic support for HTTP/1.1, HTTP/2, and HTTP/3, and incorporates advanced networking capabilities such as DNS‑over‑HTTPS, high‑performance metrics, and robust security features.

Installation

Niquests is available on PyPI and officially supports Python or PyPy 3.7+.

<code>$ python -m pip install niquests</code>

Basic Usage

<code>&gt;&gt;&gt; import niquests
&gt;&gt;&gt; s = niquests.Session(resolver="doh+google://", multiplexed=True)
&gt;&gt;&gt; r = s.get('https://one.one.one.one')
&gt;&gt;&gt; r
&lt;ResponsePromise HTTP/3&gt;
&gt;&gt;&gt; r.status_code
200
&gt;&gt;&gt; r.headers['content-type']
'application/json; charset=utf8'
&gt;&gt;&gt; r.oheaders.content_type.charset
'utf8'
&gt;&gt;&gt; r.encoding
'utf-8'
&gt;&gt;&gt; r.text
'{"authenticated": true, ...'
&gt;&gt;&gt; r.json()
{'authenticated': True, ...}
&gt;&gt;&gt; r
&lt;Response HTTP/3 [200]&gt;
&gt;&gt;&gt; r.ocsp_verified
True
&gt;&gt;&gt; r.conn_info.established_latency
datetime.timedelta(microseconds=38)</code>

You can also use async/await:

<code>import niquests
import asyncio

async def main() -> None:
    async with niquests.AsyncSession(resolver="doh+google://") as s:
        r = await s.get('https://one.one.one.one', stream=True)
        print(r)  # Output: <Response HTTP/3 [200]>
        payload = await r.json()
        print(payload)  # Output: {'authenticated': True, ...}

asyncio.run(main())</code>

Niquests makes sending HTTP requests effortless without manually constructing query strings or form‑encoding data; it also avoids mandatory compilation toolchains and only enables HTTP/3 when the platform natively supports it.
