Youtube API Limitations

Question

I m building a pretty large app for a client  and had some questions about heavy API usage   Basically this app is going to aggregate feeds from various sources  My client estimates around 900 follow-able users will be in this system to start out  with more being added over time  He wants to update the feed data every 15 minutes  so we would need to update one user feed per second  assuming 900 feeds and a 15 minute TTL  As the requests take a few seconds to complete  we would then need to load balance across a few threads to tackle the queue asynchronously   My question is  should I be worried about quota errors or hitting any kind of limitations  If so  what are our options   I ve already read their help pages and documentation  and it s very vague and not really helpful  I need concrete numbers  It s not feasible to load test their API to figure out the limitation  The matter is not helped by Google deferring all support to a non-official channel such as StackOverflow where people do not have knowledge of the Youtube internals   Thanks in advance

Version 3 of the YouTube Data API has concrete quota numbers listed in the Google API Console where you register for your API Key   You can use 10 000 units per day   Projects that had enabled the YouTube Data API before April 20  2016  have a default quota of 50M day   You can read about what a unit is here  https   developers google com youtube v3 getting-started quota   A simple read operation that only retrieves the ID of each returned resource has a cost of approximately 1 unit  A write operation has a cost of approximately 50 units  A video upload has a cost of approximately 1600 units    If you hit the limits  Google will stop returning results until your quota is reset  You can apply for more than 1M requests per day  but you will have to pay for those extra requests   Also  you can read about why Google has deferred support to StackOverflow on their YouTube blog here  https   youtube-eng googleblog com 2012 09 the-youtube-api-on-stack-overflow 14 html  There are a number of active members on the YouTube Developer Relations team here including Jeff Posnick  Jarek Wilkiewicz  and Ibrahim Ulukaya who all have knowledge of Youtube internals     UPDATE  Increased the quota numbers to reflect current limits on December 10  2013   UPDATE  Decreased the quota numbers from 50M to 1M per day to reflect current limits on May 13  2016   UPDATE  Decreased the quota numbers from 1M to 10K per day as of January 11  2019
