1️⃣ Clone and install:
git clone https://github.com/omkarcloud/crunchbase-scraper
cd crunchbase-scraper
python -m pip install -r requirements.txt2️⃣ Start the API:
python run.pyCrunchbase sits behind Cloudflare, so the first request opens Chrome for a few seconds to clear it. Every request after that is plain HTTP.
Running thousands of calls from one IP? Cloudflare can block that IP for a few hours. Set CRUNCHBASE_PROXY=http://user:pass@host:port and keep going.
3️⃣ Get your first data:
curl "http://localhost:8000/companies/details?company=openai"{
