Ask HN: Anyone know where I can download bulk horoscopes?

What you are attempting to do was done long back by a Rishi and great astrologer in ancient India named Brighu. But unfortunately large parts of his bulk horoscopes got lost. In some parts of india you get astrologers who have parts of this corpus and if your birth data is available, you will get a good accurate reading.

I will advice you to learn Vedic astrology which accounts for earths precession and hence is very accurate if your concepts are clear. Any book by B V Raman will help. Remember there are nearly a billion combinations 9 power 12. - 12 house and 9 planets. Good luck.

There are providers for newspapers. Or you could scrape a news site.
