Query "Remaining Quota" for Microsoft Cognitive Services APIs programmatically - api

I am currently using 3 Microsoft APIs: Text Analytics Api, Bing Search Api and Linguistic Api. I want to know if there's any Api or method to retrieve remaining quota programmatically for my specific Api against my Api Key?
Other thing I want to know if any Api or any method of these APIs to tell me programmatically if my key is valid or invalid.

For the first question, I do not think there is a way to check you remaining quota. If you are concerned about spending beyond your budget, you may be interested into keeping track of the number of calls you do to Microsoft Cognitive Services. In any case, this is the kind of question I suggest you should directly ask to Microsoft Cognitive Services customer services.
For the second question, there is no way to do so. If such way would exist, that would encourage malicious users to find it to generate keys at will. Assuming you have an expired key, the only way to verify its validity is to make a call to any of the Microsoft Cognitive Services APIs and check the error code message, if any.

API call request limit

I have been looking into various different APIs which can provide my the weather data I need in JSON format. A lot of these API's have certain limits such as: in order to get more requests per minute, you need to pay more money per month so that your app can make more API requests.
However, a lot of these API's also have free account which five you limited access to them.
So what I was thinking is, wouldn't it be possible for a developer to just make lots of different developer accounts with an API provider and then just make lots of different API keys?
That way, they wouldn't have to pay anything as they could stick with the free accounts. Whenever one of the API keys has reached the maximum daily request calls, the developer could just put a switch statement in their code which gets their software to use a different API key.
I see no reason why this wouldn't work from a technical point of view... but, is such a thing allowed?
Thanks, Dan.
This would technically be possible, and it happens.
It is also probably against the service's terms, a good reason for the service to ban all your sock puppet accounts, and perhaps even illegal.
If the service that offers the API has spent time and money implementing a per-developer limit for their API, they have almost certainly enforced that in their terms of service, and you would be wise to respect those.

Mailchimp API: Add emails to my app's users' email lists

Is it possible to use Mailchimp API to subscribe emails to the lists of MY USERS' Mailchimp Accounts and not my own?
Basically I have a web app, and users collect emails of various subscribers through this app. I then want them to be able to click a button and subscribe all those emails to their lists.
I've looked at Mailchimp's API - particularly the /lists/subscribe and the /lists/batch-subscribe methods. However so far it appears that these will only work for your own Mailchimp account and not for remote users' accounts.
Can someone please tell me whether what I'm trying to achieve is possible with Mailchimp's API?
You would need to execute the api-calls with your users' api-key, which would mean that you execute the calls with their credentials.
There are three different ways to get their api keys, with different practicality levels.
You guess. They look like guids without dashes, and some information about which datacenter it is associated with. Some easy (and somewhat bad) calculations indicate that there are 2^128 api keys in every datacenter, so this will consume both cpu- and network-resources, and invoke the rage of the Mailchimp. The linked image shows him on a good day. He won't be as pleasant if you choose this alternative. Dont do this.
You ask, in an evil way, for their username/password. This is bad since it will give you to all accounts those credentials works with. This would also give you access to stuff that aren't available using api calls (like payment stuff). This wont work at all if your user is intelligent administrators that are using AlterEgo, the two-factory security alternative. This alternative is less bad than blindly guessing, but still provides too much access, if it works at all.
You ask, in a user-friendly way (with perhaps some quick tutorials), for the user to generate an api-key in mailchimp to provide to you. This is the Good Alternative (tm).
You may choose any implementation as long as you choose number three.

Can client side mess with my API?

I have a website that revolves around transactions between two users. Each user needs to agree to the same terms. If I want an API so other websites can implement this into their own website, then I want to make sure that the other websites cannot mess with the process by including more fields in between or things that are irrelevant to my application. Is this possible?
If I was to implement such a thing, I would allow other websites to use tokens/URLs/widgets that would link them to my website. So, for example, website X wants to use my service to agree user A and B on the same terms. Their page will have an embedded form/frame which would be generated from my website and user B will also receive an email with link to my website's page (or a page of website X with a form/frame generated from my server).
Consider how different sites use eBay to enable users to pay. You buy everything on the site but when you are paying, either you are taken to ebay page and come back after payment, or the website has a small form/frame that is directly linked to ebay.
But this is my solution, one way of doing it. Hope this helps.
It depends on how your API is implemented. It takes considerably more work, thought, and engineering to build an API that can literally take any kind of data or to build an API that can take additional, named, key/value pairs as fields.
If you have implemented your API in this manner, then it's quite possible that users of this API could use it to extend functionality or build something slightly different by passing in additional data.
However, if your API is built to where specific values must be passed and these fields are required, then it becomes much more difficult for your API to be used in a manner that differs from what you originally intended.
For example, Google has many different API's for different purposes, and each API has a very specific number of required parameters that a developer must use in order to make a successful HTTP request. While the goal of these API's are to allow developers to extend functionality, they do allow access to only very specific pieces of data.
Lastly, you can use authentication to prevent unauthorized access to your API. The specific implementation details depend largely on the platform you're working with as well as how the API will be used. For instance, if users must login to use services provided by your API, then a form of OAuth may suffice. However, if other servers will consume your API, then the authorization will have to take place in the HTTP headers.

Google Analytics API for commercial website

This question is for anyone that used Google Analytic API on a commercial website.
For instance you have a website where members can upload music and pay for a membership to track via Analytics how many people visited their uploads.
Does Google allow to use the Analytics API for commercial use?
The Analytics API may be used for both commercial and noncommercial purposes in ways consistent with these API Terms.
http://code.google.com/apis/analytics/docs/gdata/gdataTermsOfService.html
Please refer to the lengthy Terms of Service :)
EDIT: As #yc pointed out, this is a question toward the the API (thanks btw).
While I don't think my original answer is totally correct, I think it is worth mentioning the "Privacy" paragraph in the "Regular" Analytics TOS:
PRIVACY . You will not (and will not allow any third party to) use the
Service to track or collect personally
identifiable information of Internet
users, nor will You (or will You allow
any third party to) associate any data
gathered from Your website(s) (or such
third parties' website(s)) with any
personally identifying information
from any source as part of Your use
(or such third parties' use) of the
Service. You will have and abide by an
appropriate privacy policy and will
comply with all applicable laws
relating to the collection of
information from visitors to Your
websites. You must post a privacy
policy and that policy must provide
notice of your use of a cookie that
collects anonymous traffic data.
I am by no means a lawyer, but just want to point out that you need to be careful about what data you collect. Especially when using Event Tracking and Custom Variables.
From the API page:
What does the Google Analytics Data
Export API cost?
The Google Analytics
Data Export API is free. We intend to
always provide a basic level of
service for free. As we continue to
build out more advanced features and
functionality, we may revisit this
later.

Design an API for a web service without "selling the farm"?

I'm going to try to phrase this as a generic question.
A company runs a website that has a lot of valuable information on it. This information is queried from an internal private database. So technically, the information in the database is the valuable part.
If this company wished to develop an API that developers could use to access their database of valuable & useful information, what approach should the company take?
It's important to give developers what they need. But it is also important to keep competing websites from essentially using the API to steal everything and essentially steal all traffic from the company's website.
Is there was some way the API could be used in a way that drives traffic back to the original company's website somehow? Something that gives users a reason to keep going there.
This is a design consideration that my company is struggling with that I can imagine other web-based services have come across before.
Institute API keys - don't make it public. Maybe make the signup process more complex than "anyone with an e-mail address".
Rate limit the API based on keys. If you're running more than X requests a minute, you're likely mining the database.
Don't provide a "fetch everything" API. Make the users know something to get information on it. Don't reveal what you know.
I've seen a lot of companies giving out API keys and stating a TOS that all developers must adhere to. For example, any page that uses data from the API must include your logo and a link back to your website. If any developer is found breaking the rules, the API key can be cancelled and your data is safe again.
Who is meant to use the API?
A good general method of solving this problem is to limit access to the data to end users (rather than allow applications or developers at it). Provide applications and users with identification, each, and make sure that to access a subset of the data, a combination of both user and application key is required.
Following this pattern, each user will have access to a very limited subset of the data (presumably, the data that they require for their own specific use), and you can put measures in place to enforce this. Any attempts at data-mining will become obvious.
This type of approach meshes well with capability-type security models on the server side.
