I don't see a lot of information available comparing the weather APIs that are available. What is the difference between OpenWeatherMap and Wunderground. I see that the paid version of Wunderground has some higher tiers with more features, but OpenWeatherMap's free tier allows a huge number of uses.
Are there implementation tradeoffs that aren't obvious?
Here's a comparison of different weather forecast APIs:
7 Weather Forecast API for Developing Apps
It contains a comparison of the following:

I made small python script for WorldWeatherOnline historical weather data for my personal project. The result can be saved in pandas dataframe and csv files.
Install the package:
pip install wwo-hist
Import package
from wwo_hist import retrieve_hist_data
import pandas as pd
Example code
frequency=3
start_date = '11-DEC-2018'
end_date = '11-MAR-2019'
api_key = 'YOUR_API_KEY'
location_list = ['singapore','california']
hist_weather_data = retrieve_hist_data(api_key,
location_list,
start_date,
end_date,
frequency,
location_label = False,
export_csv = True,
store_df = True)

I've been searching for an accurate free weather API and came across this answer. A lot of people are recommending Dark Sky, which shut down their API after they were acquired by Apple. Also, Wunderground which is pretty accurate because of a huge number of weather stations recently shut down their free plan. There's a pretty good comparison of OpenWeatherMap and Wunderground and a few more on Reddit.

I have been looking into the Spotify API over the last few days, and it's not clear to me whether any of the following information is available:
For artists, either their stream counts or album sales or any other metrics that indicate how popular an artist is.
Same for albums and tracks, any indication of popularity of the album or track
Here's output from their /get-artist endpoint for Kanye West:
We only receive a followers count of 16011935, which I assume is their Spotify followers, and a popularity of 95 that appears to be on a 0 - 100 scale and is presumably derived from the followers metric. As far as metrics for albums are concerned, from their /get-album endpoint:
Here we receive a popularity for Kanye's Donda album, but no other metrics associated with the album. And from their /get-track endpoint, there are no metrics at all associated with the track.
Am I missing something? Going into this, I sort of assumed that the Spotify web API would have some additional metrics on artists, albums, and tracks, but perhaps not?
Unfortunately you're correct in your analysis, as in Spotify APIs do not directly give access to any kind of streaming metrics. Also note that the popularity is a dynamic metric which changes over time, not only related to follower counts. An alternative way to get some kind of streaming info would be to look at external data sources, such as last.fm, but of course this requires you to match the two APIs.
"I've got some questions about the Azure Form Recognizer pricing. The website says $50 per 1000 pages for the S0 Web custom document type. If I upload a 1000 page PDF but make 10 API calls on each page, will we be charged per API call to the uploaded document or based purely on the number of pages? So would we expect a $50 bill or a $500 bill for those 1000 pages?"
Well, I had this same doubt and drilled down a bit more to figure out that it is based on the number of pages you analyze using the API. So in your case, since, you are calling the API which is essentially analyzing the pages of the document, the bill would be $500.
However, it is always better to save the results and refer them later as with one model the result will always be the same for the same document/page.
The documentation for the CEX exchange's REST API is quite good but it only says how to place limit orders as far as I can tell. You have to specify the price at which you want to purchase, e.g. Bitcoin, what if I just want to pay whatever the market price is? I know how to use the requests module on python to interact with a REST API.
Do you think that they plugged directly into the Twitter API, or do they have some sort of backend which is what connects to the Twitter API directly instead? I didn't realize this kind of functionality was available to standard users.

This site has a (short) piece about the technology used - it does seem like they're using the standard, public API:
"Using Twitter's API, tweets [...] were pulled, tracked and displayed
in real time
[...]
We couldn't simply pull every tweet ... A lot of research and testing
was conducted to determine which words and phrases to capture, as well
as what parameters the tweets had to follow in order to be funneled
onto the site"
Also, the site's own T&C's mention
This website contains a licensed real time display of Tweets
At a guess, they're effectively continually searching for certain terms in public tweets (as any Twitter client can do) and displaying the results.
Basically, the site uses the Twitter Streaming APIs which allow a persistent connection with Twitter. And as filtered tweets come through, it processes the data and delivers it to website users through web sockets via a 3rd party service called Pusher.
I am supposed to develop an application in which I am supposed to display weather conditions. When I enter a city that time it should get connected to any weather site suppose weather.com, and display only the weather conditions like humidity, rainfall, temperature, etc that is all sorts of weather conditions. But it should not display the complete web-page.
We are supposed to work on SDK-3.0 - in which it shows us the model of mobiles and we have to code which will be implemented on that mobile model.
So how do I connect to internet? And later how will I display only the weather on the mobile of SDK, because internet always keep on changing its format?
I am completely new to J2ME+MIDlets, and this is my first application in j2me. I want to know the detailed procedure for how to do this.
You can use Yahoo Weather API.
Have in mind that Yahoo explicitly states that their API is for non-commercial use though.
To parse the RSS returned by the API I'd recommend an XML pull parser. You'll find more information on those here.
