API

The NewsBlur API

Retrieve feeds, stories, and stats. Open source, no API key required.

Introduction to the API

NewsBlur is a personal news reader that brings people together to talk about the world. A new sound of an old instrument.

NewsBlur's API allows users to retrieve their feeds, feed counts, feed icons, feed statistics, and individual feed stories. No API key is required, but you are required to authenticate before using any of the API endpoints. Please be considerate, and don't hammer our servers.

We're quite pleased to point out that this entire API is open-source, including the implementation of the endpoints. You can find the source of the /reader/ views source, /social/ views source, /rss_feeds/ views source, as well as the API definitions in YAML.

We love pull requests. If you want to add an endpoint, modify output, or make something better, NewsBlur's repo on Github is the place to make that happen.

A Note about OAuth

NewsBlur supports OAuth but to have an OAuth enabled client you must email Samuel to request a client ID and secret. You will need to provide your NewsBlur username, redirect URI (often just your client app's website), and app name.

To use OAuth when authenticating requests, be sure to pass the Bearer HTTP header with every request, just as you would on any other OAuth API. Use the /oauth/authorize endpoint to begin the OAuth authentication procedure. Use the /oauth/token endpoint to receive your authorized token, which you can pass in with every request.

You are not required to use OAuth, in which case you will need to pass the newsblur_sessionid cookie with every request. This cookie is set on login.

authentication

POST /api/login

  • Login as an existing user.
Parameter Description Default Example
username Required Username samuelclay
password Optional Password new$blur

Tips

  • If a user has no password set, you cannot just send any old password. This is not Instapaper.

POST /api/logout

  • Logout the currently logged in user.

POST /api/signup

  • Create a new user.
Parameter Description Default Example
username Required Username samuelclay
password Optional Password new$blur
email Required Email address samuel@newsblur.com

feeds

GET /rss_feeds/search_feed

  • Retrieve information about a feed from its website or RSS address.
Parameter Description Default Example
address Required Searches the RSS and website address and returns a feed. techcrunch.com
offset Optional Try paging through feeds found by using the offset. 1

GET /reader/feeds

  • Retrieve a list of feeds to which a user is actively subscribed.
  • Includes the 3 unread counts (positive, neutral, negative), as well as optional favicons.
Parameter Description Default Example
include_favicons Optional Include favicons inline. Since they can be time consuming to download, you can optionally turn them off. Use /api/v1/feeds/favicons/ to retrieve the favicons in a separate request. false true/false
flat Optional Returns a flat folder structure instead of nested folders. Useful when displaying all folders in a single depth without recursive descent. false true/false
update_counts Optional Forces recalculation of unread counts on all feeds. The preferred method is to call this endpoint without updated counts, then call refresh_feeds to get updated counts. That way you can quickly show the user's feeds, then update the counts. Turning this option on will lead to a slower load-time. false true/false

Tips

  • Use /reader/refresh_feeds to get updated unread counts.
  • Turn off include_favicons if you can either cache favicons or can wait to fetch them.

GET /reader/favicons

  • Retrieve a list of favicons for a list of feeds. Used when combined with /reader/feeds and include_favicons=false, so the feeds request contains far less data. Useful for mobile devices, but requires a second request.
Parameter Description Default Example
feed_ids Optional Array of feed ids. Leave empty to retrieve all active (enabled) feeds. feed_ids=12&feed_ids=24

Tips

  • To use inline data images, you can use this syntax: 
    <img src="data:image/png;base64,[IMAGE_DATA_STRING]" />

GET /reader/page/:id

  • Retrieve the original page from a single feed.

GET /reader/refresh_feeds

  • Up-to-the-second unread counts for each active feed.
  • Poll for these counts no more than once a minute.

GET /reader/feeds_trainer

  • Retrieves all popular and known intelligence classifiers.
  • Also includes user's own classifiers.
Parameter Description Default Example
feed_id Optional Only use a single feed. Omit this to get the classifiers for all feeds at once. 42

Tips

  • If you only want a user's classifiers, use /classifiers/:id.
  • Omit the feed_id to get all classifiers for all subscriptions.

GET /rss_feeds/statistics/:id

  • Statistics and history for a feed.
  • Includes feed update frequencies, frequency distribution of intelligence classifiers, average stories per month over the life of the feed, and the last five feed and page fetches.

GET /rss_feeds/feed_autocomplete

include_story_content Optional If you're just checking for story ids and meta-data, you don't need the story content, thus reducing bandwidth. true false
query Optional Search for a keyword or phrase in the feed. Note that only premium users can search feeds. pizza

Tips

  • The story score (red, neutral, green) can be computed by following the function compute_story_score in reader_utils.js on GitHub. Alternatively, you can use the score parameter.
  • Counts are broken into three. Add them up for a total, but you shouldn't show or count the hidden stories:
    • ps: positive/focus count
    • nt: neutral/unread count
    • ng: negative/hidden count
  • If you aren't including hidden stories and a user has many stories that are hidden (which happens quite often as they might thumbs down the publisher but thumbs up a title or tag), then make sure to keep paging if the hidden_stories_count is non-zero. Don't rely on the stories list being empty to assume that's when to stop paging.

API Guidelines and Terms of Service

NewsBlur's API allows users to retrieve their feeds, feed counts, feed icons, feed statistics, and individual feed stories. No API key is required, but you are required to authenticate before using any of the API endpoints. Please be considerate, and don't hammer our servers.

If your project or application allows users to interact with data from NewsBlur, you must cite NewsBlur as the source of your data.

You may use the API commercially, by which we mean you may charge people money to use your project which itself uses the API. You may not, however, sell advertising against any data retrieved from NewsBlur's API. Essentially, you can charge money for your application or service, but not wrap NewsBlur in advertisements.

We reserve the right to revise these guidelines. If you violate the spirit of these terms, expect to be blocked without advance warning.
