Python script to grab data from the Internet Archive via the CDX API server, uses function from Sawood Alam's CDXSummary tool

grab-cdx.py

# grab-cdx.py

from requests import Session
from rich.console import Console
from urllib.parse import urlencode

URIR = "https://www.cnn.com/"
FROM = "20150424"
TO = "20220923"
OTHER_PARAMS = "&from=" + FROM + "&to=" + TO + "&collapse=timestamp:8&filter=statuscode:200"  # only one entry per day, 200 OK
REQSESSION = Session()
errprint = Console(stderr=True, style="red", highlight=False).print

# HELPFUL FUNCTION FROM CDXSUMMARY
# https://github.com/internetarchive/cdx-summary/blob/main/cdxsummary/__main__.py
def get_stream_from_api(url):
    pages = int(REQSESSION.get(f"{url}&showNumPages=true").text)
    for page in range(pages):
        pageurl = f"{url}&page={page}"
        errprint(f"Downloading [[cyan]{page + 1}/{pages}[/cyan]]: [magenta]{pageurl}[/magenta]")
        r = REQSESSION.get(pageurl, stream=True)
        if r.ok:
            r.raw.decode_content = True
            for line in r.raw:  yield line

def write_cdx (urir, cdxapi, params, outfile):
    url = f"{cdxapi}?{params}&{urlencode({'url': urir})}"
    input_stream = get_stream_from_api(url)
    f = open(outfile, "w")
    for line in input_stream:  f.write(line.decode())
    f.close()
    try:      input_stream.close()
    except:   pass

# MAIN
cdxapi = "https://web.archive.org/cdx/search"
params = "matchType=exact" + OTHER_PARAMS
outfile = "cnn-" + FROM + "-" + TO + "-day.cdx" 
write_cdx(URIR, cdxapi, params, outfile)

Politeness to avoid being blocked:

from random import randint, from time import sleep
last line of get_stream_from_api (inside for loop): sleep(randint(8,11))

Can also get more pages at once: (suggestion from Sawood)

for page in range(startPage, pages, 5):
pageurl = f"{url}&page={page}&pageSize=5"
