Developer's Guid for Google Web Search API (Deprecated) informs, that the number of requests you may make per day will be limited. But I can't find information about how much requests I can make... What the limitation is?
It looks like the limit is 1000 requests per day:

I understand the Twitter REST API has strict request limits (few hundred times per 15 minutes), and that the streaming API is sometimes better for retrieving live data.
My question is, what exactly are the streaming API limits? Twitter references a percentage on their docs, but not a specific amount. Any insight is greatly appreciated.
What I'm trying to do:
Simple page for me to view the latest tweet (& date / time it was posted) from ~1000 twitter users. It seems I would rapidly hit the limit using the REST API, so would the streaming API be required for this application?
You should be fine using the Streaming API, unless those ~1000 users combined are tweeting more than (very) roughly 60 tweets per second at any moment.
Using the Streaming API endpoint statuses/filter with the follow parameter, you are allowed up to 5000 users. There is no rate limit except when the stream returns more than about 1% of the all tweets being tweeted at that moment. (60 tweets per second is 1% of the average rate of tweets, which is always fluctuating, so don't rely on that number.)
If your stream does go above the 1% threshold, you can detect this. (See the LIMIT notice.) Then you would use the REST API to find missed tweets.
Twitter simply will not allow multiple streams from one registered app/account. Doing so will result in the older one being closed.
Also too many connection tries are not allowed as well and will result in a user being blocked.
Reference docs: Public Streaming API (outdated)
Have searched for answers on this for 2 days now with very little luck.
I'm developing a Drupal 7 site which has a Geofield field being autopopulated from an address field using the Google Geocoder API, but as of a couple of days ago this stopped working:
Exception: Google API returned bad status.\nStatus: OVER_QUERY_LIMIT in geocoder_google() (line 52 of /home/.../modules/geocoder/plugins/geocoder_handler/google.inc).
I can remove the proximity search filter that is sending too many requests to the Google API but I can't progress because I run into the above error every time I try to add a new record to the database (which just does one lookup to get a geocode from an address field but fails). Is there any way to unblock my site from Google's API or reset my usage? I've added an API key but to no avail. This was all working fine up until very recently, which I guess is when I unknowingly exceeded the usage limit.
I have limited API experience and am a Drupal/PHP beginner so please be gentle! Happy to provide more info, code, error messages etc if needed. Relevant Drupal 7 modules being used are OpenLayers, OpenLayers Proximity, Geofield, GeoPHP and Geocoder. Thanks for any help anyone can offer.
From Google Geocode Documentation:
Use of the Google Geocoding API is subject to a query limit of 2,500 geolocation requests per day. (User of Google Maps API for Business may perform up to 100,000 requests per day.) This limit is enforced to prevent abuse and/or repurposing of the Geocoding API, and this limit may be changed in the future without notice. Additionally, we enforce a request rate limit to prevent abuse of the service. If you exceed the 24-hour limit or otherwise abuse the service, the Geocoding API may stop working for you temporarily. If you continue to exceed this limit, your access to the Geocoding API may be blocked.
So, I guess you have to wait 24 hours, or upgrade to the business version.
What is the query limit for Yahoo's Finance API? Or where is the documentation that describes the limit?
For all of Yahoo's API's I've only been able to find general documentation for all API's. If you know where the documentation is for Yahoo's Finance API that'd also be appreciated. (I've been searching for a few days on Google, and on Yahoo's API sites, finally turned to friends at SO)
Thanks!
A 2020 update:
YQL was terminated on Jan, 3, 2019Because of this, the older answers in the questions are no longer valid. Archive has a backup of the link they mention from the day before the shutdownYou'll probably never need it, the limits have been changed anyway
Yahoo finance itself was also stopped for a while, but it's available again.It's located at https://query1.finance.yahoo.com/v7/finance (e.g. https://query1.finance.yahoo.com/v7/finance/quote?symbols=AMZN)
I also wondered about the new limits but I can't find an official answer. Online everyone seems to have another answer, but it general it boils down "a 4 digit number" every hour when using the unauthenticated (free) version.
UPDATE:
Rate limits in YQL are based on your authentication. If you use IP-based authentication, then you are limited to 2,000 calls/hour/IP to the public YQL Web service URL (/v1/public/) or 20,000 calls/hour/IP to the private YQL Web service URL (/v1/yql/) that requires OAuth authorization. See the YQL Web Service URLs for the public and private URLs. Applications (identified by an Access Key) are limited to 100,000 calls/day/key*.
However, in order to make sure the service is available for everyone we ask that you don't call YQL more than 0.2 times/second or 1,000 times/hour for IP authenticated users and 2.7 times/second or 10,000 times/hour.
See the Yahoo Query Language Usage Information and Limits page. This is for all of the YQL APIs, not just the Finance API.
YQL Rate Limits:
What this means:
Using the Public API (without authentication), you are limited to
2,000 requests per hour per IP (or up to a total of 48,000 requests a day).
Using the Private API (with OAuth authentication using an API Key), you are limited to
20,000 requests per hour per IP and you are limited to 100,000 requests per day per API Key.
The above answer was originally posted here by me.
Yahoo's YQL allows you to query Yahoo! Finance data. Their usage limits are as follows:
Unauthenticated: up to 1,000 calls/day
Authenticated: up to 100,000 calls/day
See Yahoo's Query language FAQ for more details at http://developer.yahoo.com/yql/faq/
I'm building an application that should query Google search very often. But i'm having trouble choosing which API i should use. There are so many of them - AJAX, REST, Web, SOAP, Custom and maybe something else. Some of them are deprecated now. From that list, from what i understand, only AJAX and Custom Search API are not. Custom Search API has 100 requests per day limit. Very small amount. I couldn't find any published limits for AJAX API, but it looks like i can do only 20 requests per hour or so. Also not so good.
So, which API should i use in desktop application to get as much as possible? And second question: what else i can do to increase the limit? Maybe set appropriate http headers, use API key or something else?
Does anyone know where I can find Google API Request Limits for their different services?
On simulating 500+ concurrent users it seems to fail silently fairly often (maybe 1 in 10 loads)
Any ideas?
The information is in their support resources. I am not aware of a central place, but it's all there. Searching the docs for "request limit" should usually do the trick.
The Geocoding API's limits for example can be found here.
Google Maps API Web Services and Google Static Maps API limits were cut effective a few days ago. Starting October 1st 2011 commercial web sites and apps using Google Maps API for free receive:
max of 2,500 calls/day, if modified using Styled Maps feature
max of 25,000 calls/day in total
Fusion tables are preferable to the Google Maps API alone, particularly with respect to rate limits:
Applications using the Google Fusion Tables API can send a maximum of
5 requests per second to the Google Fusion Tables server.
I think they removed the limit recently: can't even find a mention of it in documentation pages where I know for sure that it was mentioned and read about the limit removal somewhere this summer.
Even their new EULA states that their service is not limited but they remain free to limit it however they want at any moment.
500 concurrent users doesn't seem to be that much though, even if limitations where in place; are you sure it's Google what's failing?
