apiron

apiron helps you cook a tasty client for RESTful APIs. Just don't wash it with SOAP.

Gathering data from multiple services has become a ubiquitous task for web application developers. The complexity can grow quickly: calling an API endpoint with multiple parameter sets, calling multiple API endpoints, calling multiple endpoints in multiple APIs. While the business logic can get hairy, the code to interact with those APIs doesn't have to.

apiron provides declarative, structured configuration of services and endpoints with a unified interface for interacting with them.

Defining a service

A service definition requires a domain and one or more endpoints with which to interact:

from apiron import JsonEndpoint, Service

class GitHub(Service):
    domain = 'https://api.github.com'
    user = JsonEndpoint(path='/users/{username}')
    repo = JsonEndpoint(path='/repos/{org}/{repo}')

Interacting with a service

Once your service definition is in place, you can interact with its endpoints:

response = GitHub.user(username='defunkt')
# {"name": "Chris Wanstrath", ...}

response = GitHub.repo(org='github', repo='hub')
# {"description": "hub helps you win at git.", ...}
