1 00:00:00,780 --> 00:00:06,780 During the last few days, we built a program which access data from a rest API. 2 00:00:06,810 --> 00:00:15,210 Now that Rest API was built by other people, but today you learn how to build your own rest API in 3 00:00:15,210 --> 00:00:15,840 Python. 4 00:00:16,610 --> 00:00:21,800 And what you're looking at is the actual API that we will piece together. 5 00:00:22,600 --> 00:00:27,320 So this page is actually the documentation of the API that we will build. 6 00:00:27,340 --> 00:00:35,020 So the API has a home page, just like the new API has a home page where you could see the documentation 7 00:00:35,020 --> 00:00:36,220 how to use the API. 8 00:00:37,880 --> 00:00:41,400 So what we've got here is some minimal documentation. 9 00:00:41,420 --> 00:00:45,320 It tells you what the format of the end point is. 10 00:00:45,500 --> 00:00:48,560 So that's the base URL up to here. 11 00:00:48,560 --> 00:00:57,080 And then you can provide a citation and the date and that will give you temperature data about that 12 00:00:57,080 --> 00:00:58,100 particular station. 13 00:00:58,130 --> 00:01:03,050 Now, down here, you'll see a list of stations that's. 14 00:01:04,420 --> 00:01:08,500 About 6500 of them. 15 00:01:08,500 --> 00:01:10,180 So that's a lot of stations. 16 00:01:10,570 --> 00:01:14,200 And these are stations across Europe. 17 00:01:16,730 --> 00:01:24,550 So, for example, if you want the station in Stockholm, that station has a station idea of ten. 18 00:01:24,560 --> 00:01:30,950 So if you want weather for Stockholm for a particular date, you'd access an entry points like this. 19 00:01:31,250 --> 00:01:34,490 So station and date, you see, the date is at the end. 20 00:01:34,520 --> 00:01:40,720 So 1988 is the year ten is the month and 25 is the date. 21 00:01:40,730 --> 00:01:44,430 So 25th of October, 1988. 22 00:01:44,450 --> 00:01:46,280 So if we click that URL. 23 00:01:47,570 --> 00:01:49,280 So that's the URL. 24 00:01:50,380 --> 00:01:55,290 With that end point, what you get is this JSON data. 25 00:01:55,300 --> 00:01:58,910 So we have this pair of data. 26 00:01:58,930 --> 00:02:05,800 So the data we requested the station ID and then we get the temperature, which is what the user wants. 27 00:02:06,010 --> 00:02:13,570 So the temperature for that day, the average temperature for that day was -0.9 Celsius degree. 28 00:02:17,160 --> 00:02:22,140 Similarly, you can enter here any station number. 29 00:02:23,400 --> 00:02:25,320 So let's change the URL to something else. 30 00:02:25,320 --> 00:02:34,290 For example, from ten we make it 14 the same date and you see that the temperature for that date was 31 00:02:34,290 --> 00:02:35,010 11. 32 00:02:35,070 --> 00:02:41,460 So station number 14 was Salzburg in Austria. 33 00:02:42,290 --> 00:02:47,180 So those are weather observation stations and so that's the API. 34 00:02:47,510 --> 00:02:55,040 So that's a lot of data that I'll give you and you'll use this data to serve them through your API. 35 00:02:55,400 --> 00:02:59,210 So there's a lot of fun stuff to learn and extremely useful. 36 00:02:59,240 --> 00:03:02,750 So let's keep going and I'll see you in the next video.
