来自谷歌开发者工具的 JSON 链接在 Python（或浏览器）中不起作用

Question

I am trying to extract the data in the table at https://www.ecoregistry.io/emit-certifications/ra/10

Using the google developer tools.network tab, I am able to get the json link where the data for this table is stored: https://api-front.ecoregistry.io/api/project/10/emitcertifications

I am able to manually copy this json data and extract the information using this code I've written:

import json
import pandas as pd
data = '''PASTE JSON DATA HERE'''
info = json.loads(data)
columns = ['# Certificate', 'Carbon offsets destination', 'Final user', 'Taxpayer subject','Date','Tons delivered']
dat = list()
for x in info['emitcertifications']:
dat.append([x['consecutive'],x['reasonUsingCarbonOffsets'],x['userEnd'],x['passiveSubject'],x['date'],x['quantity']])
df = pd.DataFrame(dat,columns=columns)
df.to_csv('Data.csv')

I want to automate it such that I can extract the data from the json link: https://api-front.ecoregistry.io/api/project/10/emitcertifications directly instead of manually pasting json data in:

data = '''PASTE JSON DATA HERE'''

The link is not working in python or even in browser directly:

import requests
import json
url = ('https://api-front.ecoregistry.io/api/project/10/emitcertifications')
response = requests.get(url)
print(json.dumps(info, indent=4))

The error output I get is: {'status': 0, 'codeMessages': [{'codeMessage': 'ERROR_401', 'param': 'invalid', 'message': 'No autorizado'}]}

When I download the data from the developer tools then this dictionary has 'status':1 and after that all the data is there.

Edit: I tried adding request headers to the url but it still did not work:

import requests
import json
url = ('https://api-front.ecoregistry.io/api/project/10/emitcertifications')
hdrs = {"accept": "application/json","accept-language": "en-IN,en;q=0.9,hi-IN;q=0.8,hi;q=0.7,en-GB;q=0.6,en-US;q=0.5","authorization": "Bearer null", "content-type": "application/json","if-none-match": "W/\"1326f-t9xxnBEIbEANJdito3ai64aPjqA\"", "lng": "en", "platform": "ecoregistry","sec-ch-ua": "\" Not A;Brand\";v=\"99\", \"Chromium\";v=\"100\", \"Google Chrome\";v=\"100\"", "sec-ch-ua-mobile": "?0", "sec-ch-ua-platform": "\"Windows\"", "sec-fetch-dest": "empty","sec-fetch-mode": "cors", "sec-fetch-site": "same-site" }
response = requests.get(url, headers = hdrs)
print(response)
info = response.json()
print(json.dumps(info, indent=4))

print(response) give output as '<Response [304]>' while info = response.json() gives traceback error 'Expecting value: line 1 column 1 (char 0)'

Can someone please point me in the right direction?

Thanks in advance!

Posting comment as an answer:

The headers required for that api in order to retrieve data is platform: ecoregistry.

import requests as req
import json
req = req.get('https://api-front.ecoregistry.io/api/project/10/emitcertifications', headers={'platform': 'ecoregistry'})
data = json.loads(data)
print(data.keys())
# dict_keys(['status', 'projectSerialYear', 'yearValidation', 'project', 'emitcertifications'])
print(data['emitcertifications'][0].keys())
# dict_keys(['id', 'auth', 'operation', 'typeRemoval', 'consecutive', 'serialInit', 'serialEnd', 'serial', 'passiveSubject', 'passiveSubjectNit', 'isPublicEndUser', 'isAccept', 'isCanceled', 'isCancelProccess', 'isUpdated', 'isKg', 'reasonUsingCarbonOffsetsId', 'reasonUsingCarbonOffsets', 'quantity', 'date', 'nitEnd', 'userEnd'])
