How do you use Amazon's Mechanical Turk API? - amazon-web-services

I'm using Amazon's Mechanical Turk as a requester and need to automate some things (specifically bonus payments).
I feel really stupid for asking this, but... how does one actually use the MTurk API? I was reading the API reference, and it specifies some details about a lot of requests, including this one for bonus payment, but there's nothing about how to actually perform such a request. I assume it's an HTML request, but there's no mention of which endpoints to use or how to obtain keys for authorization.

You could call it via the AWS CLI or via your preferred programming language, such as Python.
For an introduction, you could do a web search and read articles like Tutorial: A beginner’s guide to crowdsourcing ML training data with Python and MTurk.

You'll need to have an AWS account and make a call from code or the CLI. For working code examples using the API in a variety of languages, check out mturk-code-samples on GitHub. The MTurk blog also has end-to-end examples.

Using Google Cloud Natural Language API with Healthcare Content

I am trying to use the Node.js SDK for the Natural Language API (#google-cloud/language). I can successfully analyze the entities for a string as per the docs.
What I want to do is analyze the same string but using the Healthcare Natural Language API. This seems like it should just be a flag or extra parameter to the language client, but I cannot find any documentation at all about how to specify which topical language API to use.
Can this be done from within the SDK or does this require making raw requests to healthcare.googleapis.com?
The Cloud Healthcare API documentation reference does not mention any language API's, at least at the moment.
So you have to use REST/RPC or maybe you can raise FR. It's not quite clear how to do this for this product, but I am sure it should be done via "Sent Feedback" button on mentioned documentation page.
Anyway, for all Google products, language APIs (like mentioned Node.JS SDK) are just convenient libraries that use REST API under the hood.
Because of the unique requirements of medical documents, the Healthcare NLP API exists separate from the general purpose NLP API.
You can analyze entities using the analyzeEntities API method
curl -X POST https://healthcare.googleapis.com/v1beta1/{nlpService=projects/*/locations/*/services/nlp}:analyzeEntities \
-d '{
"documentContent": "<your doc here>"
}'
You can find the documentation here and a how to guide here.

what are the security best practices with twilio and firebase?

I was looking for a tutorial or stackoverflow thread but I couldn't find a best practice how I can do it.
I have an ios swift app and I want to send sms if a user create an add a record in Firebase, like sending an invitation to someone or doing something which could affect other user.
According to some post on the internet and on your blog I need a server side script which makes it safe and I don't have to store those information in my swift code. Like here: https://www.twilio.com/blog/2016/11/how-to-send-an-sms-from-ios-in-swift.html
Currently I don't have a server. Only thing that I have is a Firebase account.
What is a best practice regarding security? For instance shall I create a webserver on AWS or just a AWS S3 bucket would be enough and shall I store those credentials or php codes there?
I'm quite new in the these things and unfortunately I don't know whom shall I ask.
Can somebody help me?

How to retrieve data from cloud using rest service

Our employee salary data are stored in the cloud provided by the third party. Currently, the third party need to send us a copy of the database to us and we recover it to our local server for reporting purpose. I need to build a application to retrieve the data directly from the cloud and use the only tables we need for report purpose. the third party provide restful service to do this, but since I am new to web service programming, I am kind of lost here to decide what to do. So my question is what is the best way that i could proceed this.
Any help will be appreciated.
The first place to start is to familiarize yourself with a coding language you'd like to use. You can usually find documentation from the REST API provider on the 'developer' section of their website. Once on their site, you can usually setup a developer sandbox account and grab a few quick examples from the documentation in the most popular languages i.e Java, PHP etc. Then, using the documentation, tweak the example to get the data you want for your app.
It is common for REST APIs to assign you a key/token that you will use with each request. Refer to their documentation for more examples.

Is there a service that allows to access multiple API's using unified interface and one login?

Some time ago I was browsing the web, when I found a service that allowed to access multiple API's using single, unified interface and single login.
I remember that I browsed the catalog of API's and check OCR services to see what features they offer.
I don't remember if it was a free service or paid one. I didn't bookmark it and now I can't find it. I have found only API's catalog on Programmable Web.
Is anyone knows the name of this service?
Well, after getting one vote down I decided to google more. No results. I reviewed bookmarks and... bingo!
It's called mashape.com and what I have had in mind was this catalogue.
Disclaimer: I have no connection to this service. I just liked the idea.
Edit:
I have just found API search:
{API}Search.
It does not allow to access mutiple API's using single credentials, but might be usefull for API's discovery.

Amazon products API - Looking for basic overview and information

After using the ebay API recently, I was expecting it to be as simple to request info from Amazon, but it seems not...
There does not seem to be a good webpage which explains the basics. For starters, what is the service called? The old name has been dropped I think, and the acronym AWS used everywhere (but isn't that an umbrella term which includes their cloud computing and 20 other services too?).
There is a lack of clear information about the new 'signature' process. Gathering together snippets of detail from various pages I've stumbled upon, it seems that prior to August 2009 you just needed a developer account with Amazon to make requests and get XML back. Now you have to use some fancy encryption process to create an extra number in your querystring. Does this mean Amazon data is completely out of reach for the programmer who just wants a quick and simple solution?
There seems to be a tiny bit of information on RSS feeds, and you can get a feed of items that have been 'tagged' easily, but I can't tell if there is a way to search for titles using RSS too. Some websites seem to suggest this, but I think they are out of date now?
If anyone can give a short summary to the current state of play I'd be very grateful. All I want to do is go from a book title in my database, and use Classic ASP to get a set of products that match from Amazon, listing cover images and prices.
Amazon 'widgets' can display keyword search results on my pages, but I have less control over these, and they are shown to the user only - my code can't look inside them.
Your post contains several questions, so I'll try to answer them one at a time:
The API you're interested in is the Product Advertising API (PA). It allows you programmatic access to search and retrieve product information from Amazon's catalog. If you're having trouble finding information on the API, that's because the web service has undergone two name changes in recent history: it was also known as ECS and AAWS.
The signature process you're referring to is the same HMAC signature that all of the other AWS services use for authentication. All that's required to sign your requests to the Product Advertising API is a function to compute a SHA-1 hash and and AWS developer key. For more information, see the section of the developer documentation on signing requests.
As far as I know, there is no support for retrieving RSS feeds of products or tags through PA. If anyone has information suggesting otherwise, please correct me.
Either the REST or SOAP APIs should make your use case very straight forward. Amazon provides a fairly basic "getting started" guide available here. As well, you can view the complete API developer documentation here.
Although the documentation is a little hard to find (likely due to all the name changes), the PA API is very well documented and rather elegant. With a modicum of elbow grease and some previous experience in calling out to web services, you shouldn't have any trouble getting the information you need from the API.
I agree that Amazon appears to be intentionally obfuscating even how to find the API documentation, as well as use it. I'm just speculating though.
Renaming the services from "ECS" to "Product Advertising API" was probably also not the best move, it essentially invalidated all that Google mojo they had built up over time.
It took me quite a while to 'discover' this updated link for the Product Advertising API. I don't remember being able to easily discover it through the typical 'Developer' link on the Amazon webpage. This documentation appears to valid and what I've worked from recently.
The change to authentication procedures also seems to add further complexity, but I'm sure they have a reason for it.
I use SOAP via C# to communicate with Amazon Product API.
With the REST API you have to encrypt
the whole URL in a fairly specific
way. The params have to be sorted,
etc. There is just more to do. With
the SOAP API, you just encrypt the
operation+timestamp, and thats it.
Adam O'Neil's post here, How to get album, dvd, and blueray cover art from Amazon, walks through the SOAP with C# method. Its not the original sample I pulled down, and contrary to his comment, it was not an official Amazon sample I stumbled on, though the code looks identical. However, Adam does a good job at presenting all the necessary steps. I wish I could credit the original author.
I wrote a blog post on this subject, after spending hours wading through Amazon's obscure documentation. Maybe useful as another view on the process.
I found a good alternative for requesting amazon product information here: http://api-doc.axesso.de/
Its an free rest api which return alle relevant information related to the requested product.

Since the time when the question was asked in 2009 the changes have, unsurprisingly, continued and some of the answers and links provided are now superseded or deadlinks.
As of February 2022, Amazon now provide the Product Advertising API Scratchpad for developers to try out API requests so they can get up and running in minutes:
Scratchpad is a tool to help Amazon Associates send basic requests to
the Product Advertising API. Follow the steps below and you can have a
working request with sample code in minutes.
The linked page also has onward links to pages where you may
sign up for the Associate program and Product Advertising API and access the complete API documentation.
As mentioned by #Reg Edit in his recent answer, Amazon now provides a scratchpad for their Product Advertising API, which in-fact does have a "SearchItems" endpoint which presumably returns products for a search query similar to the one a shopper would enter into Amazon's search bar while shopping.
Here's a link explaining on how to get access to Amazon's Product Advertising API. This would be helpful for anyone looking to display Amazon product's on their application programmatically.
In order to get access to Amazon's Product Advertising API, you must meet the following 3 requirements:
Have completed 3 sales in the last 180 days
Have an approved associates account
Comply with this agreement
Now if you don't meet the above requirements, the only other option Amazon gives you is to use their SiteStripe widget, which is a tool to help associates build links manually.
If you do not meet the requirements listed above and would still like to get Amazon product data for your app or website programmatically, you may use web scraping to achieve the same. Since the data is public, no one can legally stop you from scraping it. Depending on how experienced you are with programming, you could either build a scraper yourself or use a service that enables you to do so.
I have built one such service myself—it is called Amazon Product Search API and it allows users to grab search results from Amazon including product title, thumbnail, URL, etc. for any search query a user would make while shopping on Amazon. It supports all the major countries Amazon operates in.
Using this service does not require you to be an Amazon associate. Users may scrape up to 10k search results for free.
