Twitter API Rate Limiting

Reading, here are the major points:


  • Anonymous calls (things like users/show – get a user’s info) are limited to 150/hour, that’s 3,600/day. This limit is IP-based.
  • Authenticated calls (like a user’s home timeline) – 300/hour. Limit based on your app key.

Those rates are useful for a single-user app (something like TweetDeck), not useful for something like an app that crawls Twitter.
You can ask to be white-listed using this form:
If approved – you get 20,000 requests / hour. That’s more useful.

Search API

  • The rates are limited but to a higher rate than the REST API. The exact number is not disclosed.
  • Important to include a User Agent parameter, otherwise you will get a lower limit.

Streaming API

  • This is what you really need for high-volume Twitter polling. Gives you a sampling of all tweets based on optional filter you pass (e.g. user, keyword, location).
  • Have three access levels, based on what Twitter decides to give you: Spritzer (about 1% of everything), Gardenhose (10%) and Firehose (everything).
