The HarvardNews API allows you to retrieve channels (i.e., publications) and items (i.e., articles) from HarvardNews in CSV, JSON, JSONP, serialized PHP, or RSS format. The API provides a RESTful interface, which means that you can query it using simple HTTP GET requests.

HarvardNews's database contains items from 2009-08-11 through the present date.

Methods

channels

To query the HarvardNews API for channels, contact the server via URLs in this format:

http://news.cs50.net/api/1.1/channels?param1=value1&param2=value2&...

Supported parameters include:

parameter	description
callback	Required iff output is jsonp. Callback function with which response will be padded.
cid	Optional. Comma-separated list of channel IDs. If omitted, all channels will be returned.
output	Required. Format for output. Must be csv, json, jsonp, or php.
q	Optional. Query string. Supports quotes, +, and -. Be sure to URL-encode this parameter's value (as with PHP's urlencode).

If any parameters are malformed or any required parameters are omitted, an empty response will be returned along with, possibly, HTTP status code 400 Bad Request.

CSV

If you request channels in CSV format (e.g., http://news.cs50.net/api/1.1/channels?output=csv), the response will be a series of comma-delimited rows, per the below:

Note that the response's first row defines the CSV file's fields. Fields' order may change over time, so do not hardcode indices into your own code. Use that first row to determine fields' indices dynamically, per this article on parsing CSV.
