I'm trying to retrieve the price data from the following API but I keep getting this error message when I execute the code.
def upbitask_xrp_krw_get():
result = requests.get("https://crix-api-endpoint.upbit.com/v1/crix/candles/minutes/1?code=CRIX.UPBIT.KRW-XRP&count=1").json()
return result["highPrice"]
And the error message I get is
Traceback (most recent call last):
File "test.py", line 194, in <module>

File "test.py", line 130, in main
upbitask_xrp_krw = Decimal(upbitask_xrp_krw_get())

raise ValueError(errmsg("Expecting value", s, err.value)) from None
ValueError: Expecting value: line 1 column 1 (char 0)
I've successfully accessed the data from other API which only has {} brackets whereas this one has [] brackets which I assume is the problem here?
In order to use the requests module you need to import it in your script first. this is true for any Python module you wish to use.
It seems the object returned by the API endpoint is a list of JSON and not simply a JSON object. Try this:
import requests
def upbitask_xrp_krw_get():
result = requests.get("https://crix-api-endpoint.upbit.com/v1/crix/candles/minutes/1?code=CRIX.UPBIT.KRW-XRP&count=1").json()
return result[0]["highPrice"]
The [0] indicates to return the first item of the list.
Here is the result:
Update
It seems there is a rate limite that prevents to query the API to often. When you reach the limit you get a 403 response code. Here is an example how you could manage it:
import requests
def upbitask_xrp_krw_get():
result = requests.get("https://crix-api-endpoint.upbit.com/v1/crix/candles/minutes/1?code=CRIX.UPBIT.KRW-XRP&count=1")
if result.status_code == 200: # Http code 200 means success
json = result.json()
high_price = json[0]["highPrice"]
else:
high_price = None
return high_price
I'm not exactly sure why you're getting that error, but you can bypass it by just calling json.loads() on the text of the request:
result = requests.get("https://crix-api-endpoint.upbit.com/v1/crix/candles/minutes/1?code=CRIX.UPBIT.KRW-XRP&count=1")
result_text = result.text
json_data = json.loads(result_text)
return json_data[0]["highPrice"]
You'll need to import json however. Also, you'll need to get the dictionary out of the list (hence the [0]).
EDIT: This is actually really bizarre: sometimes it's printing out a result and other times it's raising an error. It could have to do with the request being different over a very short period of time.
I believe this may work better:
def upbitask_xrp_krw_get():
result = requests.get("https://crix-api-endpoint.upbit.com/v1/crix/candles/minutes/1?code=CRIX.UPBIT.KRW-XRP&count=1").json()
return result[0]["highPrice"]
Your result is a list of json data. Just need to select the index you want in the return value.
EDIT: oh neat, there are different results after subsequent requests. There must be some kind of rate limiting, the first time I hit the API I get the list, the next time i hit it I just get a 403 response
I m just a beginner in python i did some research and this worked for me
import json
import requests
url ='https://crix-api-endpoint.upbit.com/v1/crix/candles/minutes/1?code=CRIX.UPBIT.KRW-XRP&count=1'
response = requests.get(url)
data = response.json()
print(data[0]['code'])
This worked for me

What is the problem and how can I solve that ?
The problem is that JSON is not invalid. To be precise, the problem is not the link, but the file_2.txt file. So you have 2 solution: Check the file_2.text file and get a file that is correctly JSON, because this file is not. Or if you really can't get a JSON file, you can modify your code by inserting a request that applies to your file, because when you run your r (therefore a Requests) it makes assumptions about the encoding of the response based on the headers http. To change the encoding you can replace r.json () with r.text (), so like this:
import requests
r = requests.get ("http://link-short.rf.gd/codes/hello/file_2.txt")
r.text()
UPDATE
I noticed that you later changed the link in the question. Try these
import json
import requests
r = requests.get (http://link-short.rf.gd/codes/hello/package.json)
data = r.json()
or this, because it converts a string to access your JSON
import json
import requests
r = requests.get (http://link-short.rf.gd/codes/hello/package.json)
data = json.loads(r.text)
well http://link-short.rf.gd/codes/hello/file_2.txt does not supply a json.
So you could supply a link to a json file
You cannot call r.json() if r is not a json file. Since your URL points to some file_2.txt, it is not in json() format and hence r.json() will not help you.
Consider using r.text() instead
I'm trying to process this JSON using python3:
http://www.bom.gov.au/fwo/IDV60701/IDV60701.94857.json
But I'm getting the following error:
Traceback (most recent call last):
File "./weath.py", line 41, in <module>
data1 = response.json()
File "/home/dz/anaconda3/lib/python3.8/site-packages/requests/models.py", line 898, in json

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
https://jsonlint.com/
Validates the JSON as valid, so I'm not sure why this is failing.
Here is the python code:
url = "http://www.bom.gov.au/fwo/IDV60701/IDV60701.94857.json"
response = requests.get(url)
data1 = response.json()
This was working 2 week ago.
How can I fix this?
This is an issue related to the specific service endpoint you're using. They have disabled web scraping through some mechanism.
If you look at your response object, you'll see it's a 403 (forbidden) with the following message:
Potential automated request detected! We are making changes to our website therefore web scraping is no longer supported. Please contact us by filling in the details at http://reg.bom.gov.au/screenscraper/screenscraper_enquiry_form/ and we will get in touch with you.
You can verify this for yourself:
response = requests.get("http://www.bom.gov.au/fwo/IDV60701/IDV60701.94857.json")
print(response.status_code) # 403
print(response.text) # above quote
When I ran this code:
import requests
url = "http://www.bom.gov.au/fwo/IDV60701/IDV60701.94857.json"
response = requests.get(url).text
print(response)
The print returned
Potential automated request detected! We are making changes to our website therefore web scraping is no longer supported. Please contact us by filling in the details at http://reg.bom.gov.au/screenscraper/screenscraper_enquiry_form/ and we will get in touch with you.
Seems like that website has disabled web-scraping or something
I hope you're doing good.
I'm trying to get the solar radiation values from this website 'solcast.com.au' .. I have went to their API documentation and followed it here ' https://docs.solcast.com.au/#forecasts-by-location' and I have applied the code:
import requests
url = 'https://api.solcast.com.au/world_radiation/forecasts?latitude= -33.865143&longitude=151.209900&api_key=MYAPI'
res = requests.get(url)
data = res.json()
forecast = data["forecasts"]["ghi"]
print('forecastss: {} dgree'.format(forecast))
So when I run the code I'm getting this error:
Traceback (most recent call last):
File "/home/pi/Desktop/solcastoo.py", line 5, in <module>
data = res.json()
File "/usr/lib/python3/dist-packages/requests/models.py", line 897, in json

Would really appreciate your help.
As John mentioned, you need to specify in your request the format you're willing to receive.
You can do it by adding headers to your request:
import requests
url = 'https://api.solcast.com.au/world_radiation/forecasts?latitude= -33.865143&longitude=151.209900&api_key=API_KEY'
res = requests.get(url, headers={'Content-Type': 'application/json'})
data = res.json()
forecast = data["forecasts"][0]["ghi"]
print('forecastss: {} dgree'.format(forecast))
In their documentation they give you two additional options:
“Accepts” HTTP request header, eg “application/json” for JSON
“format” query string, eg “format=json” for JSON
Endpoint suffix file extension, eg “forecasts.json” for JSON
The second option doesn't work, at least for this specific request. The third option works, but it's a bit odd.
The first option is more commonly used in APIs, but be prepared to use other options too.
PS they say in the documentation that `headers={'Accepts': 'application/json'}
should give the desired result, so I'd assume it also could be a possibility in other endpoints.
Good luck
I'm trying to get some data from this website. I can enter 'text' and 'longest_only' parameters but when I pass 'ontologies' param, it says No JSON object could be decoded. Here's the complete URL http://data.bioontology.org/annotator?text=lung cancer,bone marrow&ontologies=NCIT&longest_only=true
I'm using Python 2.7
The argument is ontologies[], since you can specify more than one. Your request should be similar to the one that the online search uses:
text=lung+cancer%2Cbone+marrow&ontologies%5B%5D=NCIT&longest_only=true&raw=true
Simply execute the same search there, and use the developer tools option of your favorite browser to check what is the actual payload being sent.
This is not an answer, but the only place I can show the error that I see when executing the sample code. I placed the code in a new module in main and run it in Python 3.4.
import requests
if __name__ == '__main__':
url = 'http://bioportal.bioontology.org/annotator'
params = {
'text': 'lung cancer,bone marrow',
'ontologies': 'NCIT',
'longest_only': 'true'
}
session = requests.Session()
session.get(url)
response = session.post(url, data=params)
data = response.json()
# get the annotations
for annotation in data['annotations']:
print (annotation['annotatedClass']['prefLabel'])
I receive the following error.

I want to get elevation data from Google Earth according to latitude and longitude, but I am not able to do this. I'm not sure what I'm doing wrong but my code is shown below.

Any help appreciated.
Post is a little late but recently ran into the same problem. The solution below worked for me. Basically what Lennart said.
from urllib import request
import json
req = request.urlopen('https://someurl.net/api')
encoding = req.headers.get_content_charset()
obj = json.loads(req.read().decode(encoding))
In Python 3, binary data, such as the raw response of a http request, is stored in bytes objects. json/simplejson expects strings. The solution is to decode the bytes data to string data with the appropriate encoding, which you can find in the header.
You find the encoding with:
encoding = req.headers.get_content_charset()
You then make the content a string by:
body = req.readall().decode(encoding)
This body you then can pass to the json loader.
(Also, please stop calling the response "req". It's confusing, and makes it sounds like it is a request, which it isn't.)
