I'd like to know if the AccuWeather API is free for commercial use.
If not, how I can use it for commercial purposes?
Is there a totally free weather API that I can use for my app?
Accuweather data is not free. They will quote you for a custom service if you call their sales support. At one of my previous companies (circa 2007), we were able to get a contract with them for national hourly weather across their station network very cheap, but still not free.
If you are looking for free weather APIs, Please have a look at weather underground.
I have looked in many weather data providers looking for free weather APIs and i found that Accuweather is not free, try yr.no I use it in my website via PHP

I currently planning for build a stock trading app using react for study purpose. Is there is any api that can give realtime stock price data and if you can please suggest me a good charting package for my project.
As your question is vague, it all depends on what you want to achieve. From my experience in working in wealth management, you will not find a reliable API and especially realtime for free.
If you're making a PoC, you might want to use EOD data which is usually available for free.
EOD API shortlist:
Yahoo finance
Polygon.io
Finhub
EOD
If you really need reliable realtime data, you might want to have a look at :
Refinitiv
Six
Bloomberg
The lists written above are not exhaustive and i have no interest in any of those API's listed. Just run a proper google search and I am sure you will find what fits you.
Beside, concerning the data visualisation library your tags mention django and reactjs. It is not very clear if you want to display data from a ui framework or from django directly. Therefore I will list what I know the most :
PyGal
Seaborn
Altair
Hope my answer will give you some lights.
I'm working for a startup and we have a customer who uses Demandware for their online store.
Our company provides vouchers which are worth a specific amount of money. So customers on the retail site can enter the voucher number near the end of the checkout experience and if it's worth, say, 10 dollars, their shopping cart is updated (-10).
I have the CTO saying we just need to "drop a few lines of javascript" onto the retailer online store. But I think this requires a Demandware plugin (especially updating a shopping cart), which involves signing up for a developer or partnership account (which takes some time), learning Demand Script and building the plugin, then releasing it to Saleforce's app store. Am I correct? Is this the only way to achieve this?
Just to be clear, the functionality is: the voucher code box needs to take a voucher number, an API request is made to our service to check what it's worth, then update the cart.
That's a pretty broad question but I'll try to explain.
First off, Demandware has gone all JavaScript.
But yeah, it has a huge API so the process sounds about right the way you've described it.
Ask your client whether they have a service integrator they're working with, because that would be their job. Your job would be to provide an API so that Demandware can check whether the voucher code is valid.
Demandware is a closed community so it's unlikely to learn it unless you're working in a company that is doing Demandware development.
Oh, and if it somehow ends up being your job to develop this, a tip from me - you probably need to get access to their site's files and use the LineItemCtnr class to createPriceAdjustment() :)
The first tip from me is that Demandware got bought by Salesforce and is now branded as Salesforce Commerce Cloud, so if you hear either, they are the same thing.
You are right that you are going to have to work with Salesforce to get going. They are a cloud provider and there is no self-hosted version of the platform, so in order to do any development, you need to have a relationship with them.
So then it depends on how you get access. If the client has any sandbox environments they are willing to share with you, you could do this as a custom build working in their environment, modifying cart code to make the service call as you ask and as the previous response suggests. But then (depending on the terms you have with the client) your company may or may not be able to reuse that code for other clients. You will also have to work with them to get that integrated into their existing site, get it deployed through their processes, etc.
If you want to write something that other Commerce Cloud clients could use, then you should set up your own partner relationship with Salesforce and get a software package they call a cartridge to what they call their LINK marketplace, which is basically a big clearinghouse of integrations like yours.
Technology-wise, the platform has gone through some changes recently, going from an XML-based GUI tool to specify business logic to using CommonJS scripts to define them. If your client is a new client within the last year or two they probably have this new fully javascript implementation, but if they are an older client than that they may be using the old way, which has a steeper (read: more proprietary) learning curve.
I am looking for a method of dynamically linking product information based on the name of the product.
For example: User types in "Playstation 3", the site would then go out and grab any information it can, such as picture, retail price, etc. Ideally, it would let you choose the correct item (returns both ps3 controller and ps3 console, user can choose which). It would then use this information in a product listing.
The easiest way I can think to implement this is to use the existing API of a major retailer such as Amazon. I have a couple completely different ideas for sites, one of which would involve selling from amazon (which I would assume they would be ok with) and another which would only be data mining the information. I am concerned they would not take it very kindly if I was just stealing their images and descriptions.
Is there another way, maybe less "sneaky" way to accomplish this that wouldn't be in legally frowned upon ?
Many web-commerce companies use a data stream known as an API - EBay, Etsy, and Amazon all have API feeds for their products. If you can convince the company to allow you access to their API (usually they will give you a key/password), then you can directly access their back-end database, typically at the read-only level. Depending on the company, you can just write them directly for access.
You are correct when you say that most companies wouldn't take kindly to someone web-scraping their product directory and re-using it. That is unethical, and could lead to big trouble with larger companies with a significant legal presence.
On the other hand, there is nothing to prevent you from cobbling together several API feeds into a Mash-Up - try Yahoo Pipes! to learn the basics of API/Mash-Up integration:

Good luck, and happy development!
Many online retailers provide a product feed - either well-publicized (William M-B has listed some examples), or sorta-kinda hidden, for the purposes of affiliate marketing. They usually have terms of use around those product feeds, describing in detail what you're allowed to do with them, and exactly how many of your limbs are at risk if you don't play by their rules.
However, the mechanism you're describing sounds remarkably similar to a search engine; there's a well-established precedent for search engines indexing sites, and using their content to reason about the underlying site. Get a lawyer to validate this, but there's a good chance that your intended purpose falls under "fair use".
I'm representative of http://aerse.com.
We are building service, that do the following:
search product by name. For example: galaxy s3, galaxy s 3 or galaxy sIII
return technical specifications (CPU, RAM etc) and product images (thumbnails and high-res images)
provide API http://aerse.com/p
deal with legal issues, provide licenses & etc.
I am developing a project in cakephp. And the requirement is to integrate all types of payment getway for donet. I dont know how to integrate credit card like master card, visa, american express etc. into my project in cakephp format.
Please help me. I am very grateful to you.
CakePHP is a programming framework not a banking service.
If you need to do financial transactions, you will need to contact service providers that do this. Major banks mostly provide credit card transactions as a service. They have their own APIs and workflows, mostly something RESTlike.
See for yourself on PayPal for example:
https://merchant.paypal.com/cgi-bin/marketingweb?cmd=_render-content&content_ID=merchant/home
https://www.paypal.com/hu/cgi-bin/webscr?cmd=_merchant-outside
Cake will be a good friend implementing it, though.
Depending on which country you are conducting business in, there may be regulations to adhere to. These usually revolve around confidentiality and security, i.e. card data.
It is far easier to use third party gateways or the APIs provided by banks through their merchant accounts as you transfer the responsibility for that data to them. PayPal is the obvious one - and there are other similar payment mechanisms, but it isn't an ideal solution in every situation.
If transactions need to go straight into a business account, discuss it with your bank. Most banks have their own or a franchised solution.
We build shops with ZenCart and use SagePay as a payment solution, but I doubt it would be available outside of the UK.
Money being money, it makes money every time it is moved and a lot of people want a piece of that. As a result there are a plethora of options to choose from.
If it was a personal / non-business site, I'd use PayPal for ease. What I wouldn't do is try to build my own gateway.
Don't forget, Cake is just PHP and as such is as easy to deal with as any other PHP website. Choose your gateway provider, study its API and everything will become clear.
My application needs to retrieve information about any published book based on a provided ISBN, title, or author. This is hardly a unique requirement---sites like Amazon.com, Chegg.com, and even software like Book Collector seem to be able to do this easily. But I have not been able to replicate it.
To clarify, I do not need to search the entire database of books---only a limited subset which have been inputted, as in a book collection. The database would simply allow me to tag the inputted books with the necessary metadata to enable search on that subset of books. So scale is not the issue here---getting the metadata is.
The options I have tried are:
Scrape Amazon. Scraping the regular Amazon pages was not very robust to things like missing authors, and while scraping the smaller mobile pages was faster, they shared the same issues with robustness of extraction. Plus, building this into an application is a clear violation of Amazon's Terms of Service.
Scrape the Library of Congress. While this seems to have fewer legal ramifications, ease and robustness were again issues.
ISBNdb.com API. While the service is free up to a point, and does a good job of returning the necessary metadata, I need to do this for over 500 books on a daily basis, at which point this service costs money proportional to use. I'd prefer a free or one-time payment solution that allows me to do the same.
Google Book Data API. While this seems to provide the information I need, I cannot display the book preview as their terms of service requires.
Buy a license to a database of books. For example, companies like Ingram or Baker & Taylor provide these catalogs to retailers and libraries. This solution is obviously expensive, so I'm hoping that there's a more elegant solution I've missed. But if not, and someone on SO has had a good experience with a particular database, I'm willing to go with that.
I've tried to describe my approach in detail so others with fewer books can take advantage of the above solutions. But given my requirements, I'm at my wits' end for retrieving book metadata.
Since it is unlikely that you have to retrieve the same 500 books every day: store the data retrieved from isbndb.com in a database and fill it up book by book.
Instead of scraping Amazon, you can use the API they expose for their affiliate program: https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html
It allows about 3k requests per hour and returns well-formed XML. It requires you to set a link to the book that you show the information about, and you must state that you are an affiliate partner.
This might be what you're looking for. They even offer a complete download!

As it seems, a lot of libraries and other organisations make information such as "ISBN" available through MAchine-Readable Cataloging aka MARC, you can find more information about it here as well.
Now knowing the "right" term to search for I discovered WorldCat.org.
Maybe this whole MARC thing gives you a new kind of an idea :)
