Get all nft owners through contract address

Technical Issue Reporting
#1

Hello I have used this python code for getting all the nft owners.I got a response in the form of a couple of apiā€™s but that apiā€™s was giving this error

{ā€œmessageā€:ā€œAPI KEY missing from x-api-key headerā€}

Here is my python code:

import requests
import pandas as pd
import time
from tqdm import tqdm
pd.set_option(ā€˜display.max_colwidthā€™, None)

import moralis

print(moralis.utils.web3_api_version(api_key=ā€˜6vOnQdQcX1bobkZdmXaOmpHqShIJBxIJB12clWUu9TLX5XXWXtz1O4uiaxkuIsLfā€™))

it prints {ā€˜versionā€™: ā€˜0.0.53ā€™}

import requests
import time

def get_nft_owners(offset, cursor):
print(ā€œoffsetā€, offset)
url = ā€˜https://deep-index.moralis.io/api/v2/nft/0x63e2938F85AC8C21F8099458A73A19fe4a33Ce00/owners?chain=polygon&format=decimalā€™
if cursor:
url = url + ā€œ&cursor=%sā€ % cursor

print("api_url", url)
headers = {
    "Content-Type": "application/json",
    "X-API-Key": "6vonqdqcx1bobkzdmxaomphqshijbxijb12clwuu9tlx5xxwxtz1o4uiaxkuislf"
}
statusResponse = requests.request("GET", url, headers=headers)
data = statusResponse.json()
print("HTTP headers:", statusResponse.headers)
try:
    print("nr results", len(data['result']))
except:
    print(repr(data))
    print("exiting")
    raise SystemExit

cursor = data['cursor']
print(data['page'], data['total'])
return cursor

cursor = None
for j in range(0, 10):
cursor = get_nft_owners(j*5000, cursor)
print()
time.sleep(1.1)

what is the error that you get on the second python script? the one that makes http requests directly without the sdk

#3

the code that you used is from this example?
https://v1docs.moralis.io/misc/rate-limit#example-of-how-to-use-cursor-python

#4

The code is executing properly.But when I clicked on the api this is appearing.
{ā€œmessageā€:ā€œAPI KEY missing from x-api-key headerā€}.I have also attached a screenshot.

#5

That error is expected fi you open that url in the browser, it needs the api key set in the http header in order to work.

#6

Yes then where to exactly place that api key in the http header. I am directly opening it in the google chrome browser.

#7

Now this is one of the urlā€™s

Exactly where to place the api key?

#8

In the http header, not in the url, you will have to use postman or other tool that can add a field in the http header

#9

Ok I got this kind of a response by using postman which I am attaching in the attachments.Is this correct?I also wanted to know in one response I will be getting 500 records right.

That looks ok, that response, the number of results in a page is 100, you have to use pagination (that cursor parameter) to get the other results if there are more than 100 results

#11

Well its giving me the results but it canā€™t be automated.I got a couple of apiā€™s and each api I have to compy and paste it in postman.From one api I will get 100 records only.So its does become a manual process in the end.

#12

you can write a script to do that automation

#13

But how will I be able to that. If you have such a script please do help me.

#14

There is a python example in documentation for how to use pagination.
