How do web comparison websites like kayak get their data? - api

I have been looking online and saw many similar/same posts but all were extremely old (latest I found was from 2011) so since technology changes, I thought I ask too.
I wonder how a flight comparison website (where you cannot book flights and can only be redirected to other websites) get their data.
Is it all by now through api's or is it throgh scrapping data (which would be not so reliable)? Ive been reading online, trying to find out if thats the case but it doesnt really seem that EVERY airline and EVERY flight search website (with booking option) provides an api. So I wonder how sites like Kayak get their data if not every airline/every flight booking website provides an api?
Also, I came across some api's like
QPX Express API
skyscanner travel api (which I checked out on some website which is using it and it does seem that data is quite limited ?!)
Travelport api
Amadeus API
Sabre travel api
Wego Affiliate Network (which seems really great but search takes super long)
I wonder if anyone has experience with the mentioned api's and how good their are /if using them is 'the way' of doing it or if its actually much more realiable to request data directly from each airline and booking website (if thats possible)?
Thanks a lot!

If we take Kayak as the example, as that is who you mentioned, they approach the data in two forms.
They have API PULL connections to GDS companies (i.e. Sabre), some airlines and large online travel companies such as Expedia etc.
Smaller airlines in particular PUSH their inventory and fares from their inventory to companies such as Kayak.
Aggregation companies generally provide PUSH access though companies who want to PUSH their data have to comply with the aggregators requirements/standards.
It is a supply and demand service. Aggregation companies will generally request access to large established companies, however, will also allow companies to push their data to them if they wish.
The data is not normally scrapped, it is through API and web service platforms.

Is there an API or other data source for FlightRadar24 aircraft flight path?

I would like to know if there is an API that gives freely the flight paths of all aircraft currently flying or that had flight some days ago over the world. It could be in any projection and any format. I imagine that it would be most likely a table with each row being an aircraft/flight and the correspondent geopath in one column.
Thanks.
I was looking around for the same topic.
The terms and conditions for getting data from Flightradar24 are shown there
https://www.flightradar24.com/terms-and-conditions
... they talk only about getting data after a business contract on the kind of data (e.g. flights with a specific filtering) and on the format (JSON, CSV, ?). With the contract one may download the data, maybe via an API.
My conclusion: Flightradar24 does not share its full set of data, only a limited set with payment.
Searching for "Flightradar24 API" you will find some sites offering Flightradar24 data via their own API primarily requiring payment, a few for free at a very low level.
You will also find some software projects for accessing and processing data from the Flightradar24 sites with a focus on Python. But these software packages build on tracking the access of the Flightradar24 site from a mobile app or the desktop browser. Result: a few accesses of an endpoint may work then comes the stop sign: Flightradar requires an authenticated access.

Static data query - self service Amadeus API in production environment

I am currently developing a web app using self-service Amadeus API in a production environment, I have questions related to the static data, kindly reply.
Questions:
1. Is there any static data available related to flights schedule or any other detail which we can store on our end and get it synced in some scheduled manner, in place of fetching all data every time using APIs.
2. In case we have static data then what will be the ideal time duration to refresh data.
3. Are we allowed to store real-time data on our end temporarily? If yes then for what duration we can keep a copy of same.
4. Is there any API where we will send a list of Flight/Segment Id and get details only of those selected records. What I mean is we like to know details of 10 specific flights/segments. So can we get the information related to those 10 flights/segments whose id we will pass to API?
5. What's the response time of search API and API which returns details of the flight.
6. What all filters available in search API to filter data.
As of today, ee do not provide static data for flights schedule

You are allowed to store the data coming from the flight search API as long as you do not resell it in any way. Keep in mind that this data changes a lot (price/availability)
You can use the Flight Offers Price API for this. Flight Offers Price takes a list of flight-offers (that you get by using the Flight Offers Search API). For those flights-offers the API revalidates the price and the availability.
It depends on where you are based, which API you use and how you use it (filters), you can try our APIs for free in our test environment. Keep in mind that the test environment is limited in terms of the number of API calls, data and has a slower response time than the production environment
Our catalog is fully open (no need to register) you can find the Flight Offers Search reference documentation here listing all the parameters available. The Flight Offers Search API has 2 endpoints:
GET a simpler version of the search, easy and fast to implement but offering less filtering
POST offering a full access to all the functionalities of the flight search

What do the Google Analytics related API's buy me that the Google Analytics UI cannot achieve?

Long time ago, I took and passed the Google Analytics IQ certification test. At the time, I don't believe there were such things as Core Reporting API, Management API, and Metadata API (and probably some other Google Analytics related API's that I don't know about). Now that I am going through the Google Analytics IQ certification training course again (provided by Google, presented by Justin Curtoni?? I believe that's his name), I found that they now have Core Reporting API, Management API, and Metadata API.
I am a computer programmer by trade; so, I have no problem with programming using these API's. However, what I don't understand is, what do these API's buy me that the Google Analytics UI cannot offer? There is no reason to write a program that utilizes these API's simply because I can do it. To me, the existing Google Analytics UI has a lot of tools, reports, and other features that quite extensive. I am hoping that some of you can help me see something that I am probably missing.
The APIs are primarily for programmatic access. For example, if you need to create 1000 accounts all with the same property/view structure and then maybe add a few view filters to each of those accounts, you'll probably want to use the Management API. Doing that by hand would be a nightmare.
The same thing is true for the reporting API. Maybe you want to set up task that runs every monday morning and reports on the previous weeks data. And maybe you want to display that data on an internal dashboard for your company using some fancy charting library. You'd have to use the API to get the data.
Dashboards (executive summaries; managers often want nice visualizations instead of boring drill-downs)
Custom reports for user groups that do not have a Google Account or are not supposed to have access to full reports (e.g. Affiliates)
advanced filtering and aggregation (GA report cannot do everything)
You can combine analytics data with external data (e.g. you are not allowed to store personally identifiable information within GA; but you might store a custom key that allows you to link analytics data to customer data from you CRM or fulfillment system)
Machine-to-machine communication; I once did tracking for an airline that needed trend data on what people where searching for and what they where actually booking; that data was used to allocate/withdraw resources from busy/lame flights, and part of this was done by hooking up GA to their backend system
Take a look at the GA Partner Page. I would say the primary reason is to "liberate" GA Data from outside of GA itself. As Eike mentions, you can create dashboards and combine this data with other sources for a complete "View" of your online presence.
HI I guess there is no definite answer. Here are some things you can do with the APIs:
Automating AdWords CRO based on keyword ad and campaign performance.
Scoring leads based on Analytics data (Engagement with different items) and external data from a CRM.
Collecting unsampled data using multiple daily queries
Filtering using several dimension.
Tracking conversions for periods longer than supported by AdWords.
Looking at a funnel via segments
Analyzing funnels with non-linear structures
Create more robust alerts
Export data to BigQuery and analyse it together with data from other systems.
Create Machine learning apps for behavioural customizing your site.
Create a dashboard with data from multiple views
Use product recommendation to implements "better together" in an online store.
Automate creation of accounts and properties + their integration in a Hosting provider's console.
Cheers!!

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.

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.
