# lazr.restfulclient — A programmable client library that takes advantage of the commonalities among lazr.restful web services.

License: copyleft · Maintenance: active · Downloads: 478.7K/mo

## What it is and what it does

lazr.restfulclient is a Python HTTP client library designed specifically for consuming lazr.restful web services. It sits on top of wadllib (which handles WADL—Web Application Description Language—parsing) and adds higher-level abstractions to simplify working with REST APIs that follow the lazr.restful conventions. The library handles authentication via oauthlib, makes HTTP requests through httplib2, and uses distro for platform detection.

The package is intended for developers building tools or integrations that need to talk to lazr.restful-based services. It abstracts away boilerplate HTTP and authentication logic, letting you work with REST resources as Python objects rather than raw HTTP calls. It supports Python 3.8 through 3.14 and is in production-stable status, making it suitable for production use in projects that depend on lazr.restful APIs.

Use it for:

- Building command-line tools or scripts that interact with Launchpad or other lazr.restful services.
- Automating workflows that require programmatic access to REST APIs following lazr.restful conventions.
- Integrating lazr.restful-based services into larger Python applications without hand-coding HTTP requests.
- Testing or monitoring lazr.restful web services by consuming their WADL descriptions and making authenticated calls.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

A programmable HTTP client library for lazr.restful web services that builds on wadllib to provide standardized access patterns across compatible REST APIs.

Yes, if you need to consume a lazr.restful web service. The library is actively maintained, has low install friction, no known security vulnerabilities, and is in production-stable status. The LGPL v3 copyleft license is standard for this project ecosystem and poses no barrier for most use cases. Install it only if you're actually targeting a lazr.restful API; it's not a general-purpose REST client.

## Install

pip install lazr-restfulclient
uv add lazr-restfulclient
poetry add lazr-restfulclient

## Installing lazr.restfulclient

Before you install: Low friction install with a recent release (13 days old) and active maintenance status. Four runtime dependencies (distro, httplib2, oauthlib, wadllib) are all standard libraries with no known complications.

License in practice: Licensed under LGPL v3 (copyleft). You must disclose source code modifications and distribute under the same license if you distribute the package; internal use has no obligation.

Quickstart:

pip install lazr-restfulclient

from lazr.restfulclient.client import RestfulClient

client = RestfulClient(service_root_uri, oauth_token=token)

Requires a valid lazr.restful service endpoint and OAuth credentials (token or consumer key/secret) for authentication.

Verify before relying:

- Whether wadllib is actively maintained and whether its stability affects this package's reliability.
- Performance characteristics when handling large or complex REST API responses.
- Specific lazr.restful service compatibility requirements beyond the library's own API.
