Quick script I wrote to easily get the download link to an IPSW for an iOS device with an iOS version/buildid + device identifier

ipsw-dl.py

#!/usr/bin/env python3

import argparse
import requests
import sys


class IPSW:
	def __init__(self, device, version=None, buildid=None):
		self.device = device
		self.version = version
		self.api = self.get_api()

		if buildid is not None:
			self.version = self.buildid_to_version()

		self.ipsw_url = self.get_ipsw()

	def get_api(self): return requests.get(f'https://api.ipsw.me/v4/device/{self.device}?type=ipsw').json()

	def get_ipsw(self): return next(self.api['firmwares'][x]['url'] for x in range(len(self.api['firmwares'])) if self.api['firmwares'][x]['version'] == self.version)

	def buildid_to_version(self): return next(self.api['firmwares'][x]['version'] for x in range(len(self.api['firmwares'])) if self.api['firmwares'][x]['buildid'] == self.buildid)

def main():
	parser = argparse.ArgumentParser(description='IPSW-DL - Easily download iOS IPSWs', usage="ipsw-dl -d 'device' -i 'iOS version' -b 'buildid'")
	parser.add_argument('-d', '--device', help='Device identifier', nargs=1)
	parser.add_argument('-i', '--version', help='iOS Version', nargs=1)
	parser.add_argument('-b', '--buildid', help='iOS Build ID', nargs=1)
	args = parser.parse_args()

	if not args.device:
		sys.exit(parser.print_help(sys.stderr))

	if not args.buildid:
		ipsw_info = IPSW(args.device[0], version=args.version[0])
	elif not args.version:
		ipsw_info = IPSW(args.device[0], buildid=args.buildid[0])
	else:
		sys.exit(parser.print_help(sys.stderr))

	print(f'IPSW URL for device {args.device[0]}, iOS {ipsw_info.version}: {ipsw_info.ipsw_url}')

if __name__ == '__main__':
	main()
