A Declarative HTTP Client for Python

Uplink

• Builds Reusable Objects for Consuming Web APIs.
• Works with Requests, aiohttp, and Twisted.
• Inspired by Retrofit.

A Quick Walkthrough, with GitHub API v3

Uplink turns your HTTP API into a Python class.

from uplink import Consumer, get, Path, Query


class GitHub(Consumer):
    """A Python Client for the GitHub API."""

    @get("users/{user}/repos")
    def get_repos(self, user: Path, sort_by: Query("sort")):
        """Retrieves the user's public repositories."""

Build an instance to interact with the webservice.

github = GitHub(base_url="https://api.github.com/")

Then, executing an HTTP request is as simply as invoking a method.

repos = github.get_repos(user="octocat", sort_by="created")

The returned object is a friendly requests.Response_:

print(repos.json())
# Output: [{'id': 64778136, 'name': 'linguist', ...

For sending non-blocking requests, Uplink comes with support for aiohttp and twisted_.

Extra! Extra!

Further, uplink has optional integrations and features. You can view a full list of available extras here.

When installing Uplink with pip, you can select extras using the format:

$ pip install -U uplink[extra1, extra2, ..., extraN]

For instance, to install aiohttp and marshmallow support:

$ pip install -U uplink[aiohttp, marshmallow]

User Testimonials

Michael Kennedy (@mkennedy), host of Talk Python and Python Bytes podcasts-

Of course our first reaction when consuming HTTP resources in Python is to reach for Requests. But for structured APIs, we often want more than ad-hoc calls to Requests. We want a client-side API for our apps. Uplink is the quickest and simplest way to build just that client-side API. Highly recommended.

Or Carmi (@liiight), notifiers maintainer-

Uplink's intelligent usage of decorators and typing leverages the most pythonic features in an elegant and dynamic way. If you need to create an API abstraction layer, there is really no reason to look elsewhere.
