I am implementing an application that should react to live chat messages.
In a first test I simply called https://www.googleapis.com/youtube/v3/liveChat/messages to get the chats and author details (parameter part=snippet,authorDetails). The response indicates pollingIntervalMillis: 1000 so in theory I could call the API every second. However my little manual testing (without automated polling) already used a stunning 120 Quota Usage out of a 10.000 daily limit?
Am I doing something wrong?
Will I get lower usage if I specify something like a fields parameter to only ask for the needed data (message text + author name)?
I have the feeling to have missed some important thing to cut down the quota usage? Or is this simply not a supported use case?
Is there something like a streaming API that pushes new messages to my server?

I have a very simple message and getting the v3 youtube data api to get the list of comments. I am just fetching the list of videos and then fetching the comments (at frequency of 5 sec) to get updated messages. using the page token as needed to minimize the load and computaion.
Today after some time while internally testing the application i started getting the quota exceeded exception. I know the youtube provided by default 10000 units and since reading the comments (and videos as well) is just 1 unit, i should expect to get similar numbers.
However, the data is wrongly calculated.
Following are request details
If you see, there are 2895 total requests LiveChatMessages-> List.
However, when i go to IAM-> Quotas, it showed 14k earlier, then 12.6k in quota usage
There seems to be some problem either with the computation or with the Documentation that defines the units for queries. Can someone help please..
PS: Just using the two apis as mentioned above in screenshot. Both are list.
If you see, there are 2895 total requests LiveChatMessages-> List. However, when i go to IAM-> Quotas, it showed 14k earlier, then 12.6k in quota usage
Yes i can see that there are 2895 requests, but how do you know what the qutoa costs are for those requests. You are using the YouTube Live Streaming api for those requests. Not the YouTube-Data-api
There is no documentation of the quota cost for the YouTube Live Streaming api calls. If Google says you used all your quota then you probably have.
I would post an issue over on the issue forum asking them to document the quota cost for the calls Issue forum
I'm currently developing a chat bot for one specific YouTube channel, which can already fetch messages from the currently active livechat. However I noticed my quota usage shooting up, so I took the "liberty" to calculate my quota cost.
My API call currently looks like this https://www.googleapis.com/youtube/v3/liveChat/messages?liveChatId=some_livechat_id&part=snippet,authorDetails&pageToken=pageTokenIfProvided, which uses up 5 units. I checked this by running one API call and comparing the quota usage before and after (so apologies, if this is inaccurate). The response contains pollingIntervalMillis set to 5086 milliseconds. Currently, my bot adds that interval to the current datetime and schedules the next fetch at that time (using Celery), so it currently fetches messages at a rate of 4-6 seconds. I'm gonna take the liberty and always wait for 6 seconds.
Calculating my API quota would result in a usage of 72.000 units per day:
10 requests per minute * 60 minutes * 24 hours = 14.400 requests per day
14.400 requests * 5 units per request = 72.000 units per day
This means that if I used the pollingIntervalMillis as a guideline for how often to request, I'd easily reach the maximum quota of 10.000 units by running the bot for 3 hours and 20 minutes. In order to not use up the quota by just fetching chat messages, I would need to run 1 API call per minute (1,3889 approximately). This is very unfeasible for a chatbot, since this is only for fetching messages and not even sending any messages to the chat.
So my question is: Is there maybe a more efficient way to fetch chat messages which won't use up the quota so much? Or will I only get this resolved by applying for a quota extension? And if this is only resolved by a quota extension, how much would I need to ask for reliably? Around 100k units? Even more?
I am also asking myself how something like Streamlabs Chatbot (previously known as AnkhBot) accomplishes this without hitting the quota limit despite thousands of users using their API client, their quota must probably be in the millions or billions.
And another question would be how I'd actually fill out the form, if the bot is still in this "early" state of development?
You pretty much hit the nail on the head. Services like Streamlabs are owned by larger companies, in their case Logitech. They not only have the money to throw around for things like increasing their API quota, but they also have professional relationships with companies like Google to decrease their per unit cost.
As for efficiency, the API costs are easily found in the documentation, but for live chat as you've found, you're going to be hitting the API for 5 units per hit. The only way to improve your overall daily cost with your calls is to perform them less frequently. While once per minute is clearly excessively long, once every 15-18 seconds could reduce the overall cost of your API quota increase, while making the chat bot adequately responsive.
Of course that all depends on your desired usage of the data, but still a recommendation if you're implementing the bot still in the realm of hobbyist usage.
I recently began using the Youtube Data v3 API for a program that I'm writing which is purely for personal use. To give a brief summary of what it does, it checks the the live chat from my most recent (usually ongoing) livestream and performs actions based on certain keywords entered in chat (essentially commands for people to use from live chat). In order to do that, however, I have to constantly send requests to get a refreshed livechat. As it is now, it sends requests on 1 second intervals. I recently did a livestream to test out my program and it only took about 25 minutes for me to reach the daily quota limit of 10,000 units/day.
The request is:youtube.liveChatMessages().list(liveChatId=liveChatId,part="snippet")
It seems like every request I make costs 6 units, according to the math. I want to be able to host livestreams at lengths of up to 3 hours, which would require a significant quota increase. I'm aware that there is an option to fill out a form to request additional quota. However, it asks for business information such as a business name, business website, business mailing address, etc. Like I said before, I'm doing this for my own use only. I'm in no way part of a business, and just made my program as a personal project. Does anyone know if there's any way to apply for additional quota as an individual/hobbyist? If not, do you think just putting n/a in those fields would be acceptable? I did find another post where someone else had the exact same problem, but no one was able to give a helpful answer. Any advice would be greatly appreciated.
Unfortunately, and although only related, it seems as Google is for the money here. I also tried to do something similar myself (a very basic chat bot just reading the chat messages), and, although some other users on the net got some different results, they all have in common that, according to the doc how it should be done, all poll at this interval of about once a second (that's the timeout one get as part of the answer to a poll for new messages). I, along with a few others, got as most as about 5 minutes with polling once a second, some others, like you, got a few more minutes out of it. I changed the interval by hand in incrementing intervals of 5 seconds each: 5, 10, 15, etc... you get the picture. I can't remember on which value I finally tuned in, but I was only able to get about 2 1/2 hours worth with a rather long polling interval of just once every 10 seconds or so - still way enough for a simple chat bot just reading the chat. But also replying would had at least doubled the usage and hence halfed the time.
It's already a pain to get it working as an idividual as just setting up the required OAuth authentication requires one to at least provide basic information like providing a fixed callback and some legal and policy information. I always ended up in had it rejected with this standard reply "Your project seem to be for internal use only.". I even was able to got this G suite working (before it required payment) to set up an "internal" project (only possible if account belongs to a G suite organization account), but after I set up the OAuth login I got the error that my private account I wanted to use the bot on was not part of the organization and hence can't be used. TLDR: Just useless waste of time.
As far as I'm in for this for several months now there's just no way to get it done as a private individual for personal use. Yes, one can just set it up and have the required check rejected (as it uses the YouTube data API scopes), but one still stuck with that 10.000 units / day quota. Building your own powerful tool capable of doing more than just polling once every 10 to 30 seconds with just a minimum of interaction doesn't get you any further than just a few minuts, maybe one or two hours if you're lucky. If you want more you have to set up a business and pay for it - simple and short: Google wants you to pay for that service.
As Mixer got officially announced to be shut down on July 22nd you have exactly these two options:
Use one of the public available services like Streamlabs, Nightbot, etc ... They're backed by their respective "businesses" and by it don't seem to have those quota limits (although I just found some complaints on Streamlabs just from April - so about one month prior to when you posted this question where they admitted to had reached their limits - don't know if they already got it solved).
Don't use YouTube for streaming but rather Twitch - as Twitch doesn't have these limits and anybody is free to set up an API token either on the main account or on a second bot account (which is also explicitly explained in their docs). The downside of this are of course the objective sacrifices one has to suffer: a) viewers only have the quality of the streamer until one reaches at least affiliate b) caped at max 1080p60 with only 6.000kBit/s c) only short time of VOD storage
I myself wanted to use YouTube as my main platform (and currently do, but without my own stuff at the moment) and my own bot stuff and such as streaming on YouTube has some advantages over Twitch, but as YouTube wants me to pay what others (namely: Twitch) offer me for free (although overall not as good quality) it's an easy decision to make. Mixer looked promissing, as it also offered quite some neat features (overall better quality than Twitch, lower latency), but the requirements to get partner status were so high (2.000 followers along with another insane high number to reach) and Mixer itself just so little of a platform (I made the fun to count all the streamers and viewers - only a few hundred streamers with just a few 10.000s viewers the whole platform had less than some big Twitch channels on their own) - and now it's announced soon to be dead anyway.
Hope this may give you some input into what a small streamer has to consider and suffer from when chosing a platform - but after all what I experienced I have these information: Either do it like all the others: Stream on Twitch and use YouTube as an archive to export to from Twitch (although Twitch STILL doesn't have an auto-export of the latest VOD implemented - but I guess that could be done by some small script) - or if you want to stay on YouTube use some existing bot like Nightbot or any of the other services like Streamlabs.
If you get any other information on how to convince Google to increase the limit as an individual please let us know.
I have a daily running task that pulls down some metrics from the YouTubeAPI based a collection of products that I want to monitor the activity for. That collection of products tends to grow over time and I'd like to set up an alert for when I get close to exceeding my daily quota limit so that I can either make a quota increase request or reduce the collection's size rather than having a gap in my metrics if I hit the limit without realizing it.
Haven't found anything in the Google API documentation for being able to query your current quota consumption or even a way to set up an e-mail alert in the console itself.
I'm not opposed to having my task track its usage internally but would prefer getting those numbers directly from the API itself and try to avoid a potential bug on my end.
Well, AFAIK you cannot query it using an API request, but you can check your daily usage in the Developer Console. Just Go to the API you want to check, then on the Overview part you can check the traffic there. Then the total response code will tell you the total count that you make a request in this API.
For more information, check this documentation that tells you that:
You can see your current usage in the quota tab for your project in the Google APIs Console.
To view or change usage limits for your project, or to request an increase to your quota, do the following:
If you don't already have a billing account for your project, then create one.
Visit the Enabled APIs page of the API library in the API Console, and select an API from the list.
To view and change quota-related settings, select Quotas. To view usage statistics, select Usage.
I'm using the Twitter search API (for example: http://search.twitter.com/search.rss?q=%23juventus&rpp=100&page=4)
I read here: http://search.twitter.com/api/ this:
We do not rate limit the search API under ordinary circumstances, however we have put measures in place to limit the abuse of our API. If you find yourself encountering these limits, please contact us and describe your app's requirements.
The limit seems random: sometimes I do 150 requests sometimes 300, generally, after 5 minutes I can do other requests.
I was wondering if is it possible do more requests
They'll detect floods and throttle accordingly rather than publisher defined limits, which is why it appears random. It'll also no doubt be based on load from other sources at the time.
If you need lots more, then they gave you the answer - contact them telling them why.
