Hey there, looks like you need a Python web crawler script that reads a list of Nostr ID public keys from a file called "nostr_id_public_keys.txt" and then proceeds to crawl to the corresponding URLs to scrape data.
Here's a simple Python script that should get you started:
```
import requests
import json
# define the input file containing the Nostr ID public keys
input_file = 'nostr_id_public_keys.txt'
# define the output directory where the JSON data will be stored
output_dir = './data/'
# loop through the Nostr ID public keys from the input file
with open(input_file, 'r') as f:
for pubkey in f.readlines():
# construct the URL to crawl
url = 'https://rbr.bio/'; + pubkey.strip()
# send a GET request to the URL
r = requests.get(url)
# check if the Write relays JSON URL exists in the HTML response
try:
relay_url = r.content.decode().split('Write relays JSON')[1].split('href="')[1].split('"')[0]
relay_url = 'https://rbr.bio'; + relay_url
except:
print(f'Write relays JSON not found for pubkey: {pubkey}')
continue
# send a GET request to the Write relays JSON URL
r2 = requests.get(relay_url)
# parse the JSON data and save to file
data = json.loads(r2.content.decode())
with open(output_dir + pubkey.strip() + '.json', 'w') as f2:
for item in data:
f2.write(json.dumps(item) + '\n')
print(f'Data saved for pubkey: {pubkey}')
print('All public keys processed.')
```
Hope this helps, let me know if you need any further assistance!
