💵 Optional Costs (Only If You Want Them)

AI Summarization (OPTIONAL)

• OpenAI API - ~$0.01-0.05 per meeting summary (GPT-4o-mini)
  • Only needed if you want AI-generated summaries
  • Can skip this and just use transcripts
  • Or use free alternatives like Llama 2 (self-hosted)

Cloud Deployment (OPTIONAL)

• Databricks - $0 (Community Edition) or paid tiers for scale
• AWS/Azure/GCP - Pay-as-you-go if you deploy to cloud
  • But can run entirely locally for FREE

📊 Cost Comparison

❌ What We DON'T Pay For:

• ❌ Search APIs (Google Custom Search, Bing API) - Would cost $5-50/1000 queries
• ❌ Data vendors (LexisNexis, Westlaw) - Would cost $100s-$1000s/month
• ❌ Proprietary databases - Would cost $1000s/year
• ❌ Meeting data APIs - Don't exist for most municipalities
• ❌ Legistar API access - FREE (they have public APIs)
• ❌ Granicus subscriptions - Not needed (data is public)
• ❌ Web scraping services - Not needed (we build scrapers)

✅ What We DO Use (All FREE):

• ✅ Official government datasets (Census, CISA, NCES)
• ✅ Academic datasets (MeetingBank, LocalView)
• ✅ Open-source civic tech (Council Data Project)
• ✅ Public government websites (Legistar, Granicus, CivicPlus, Municode)
• ✅ Open-source software (PySpark, Delta Lake, Python)

❓ FAQ

Q: Don't we need to pay Legistar for API access?

A: No. Legistar hosts public meeting data that is FREE to access. They have public websites (e.g., chicago.legistar.com) that we can scrape for free. Some cities also provide Legistar APIs for free.

Q: Is Granicus a paid service?

A: Not for us. Granicus is a platform that municipalities pay for, but the meeting videos and agendas are publicly accessible by law. We access this FREE public data via web scraping.

Q: What about API rate limits?

A: We use respectful web scraping (not APIs), with delays between requests to avoid overloading servers. This is standard practice and legal for public data.

Q: Can I really get 10,000+ jurisdiction URLs for free?

A: Yes. LocalView has 1,000-10,000 URLs ready to download. Council Data Project has 20 cities configured. City Scrapers has 100-500 agencies. Legistar enumeration can yield 1,000-3,000 more. All free.

Q: What if I want to scale beyond 10,000 jurisdictions?

A: Still free. Just use cloud infrastructure (AWS/Azure/GCP) with pay-as-you-go pricing for compute, but the DATA access remains free. Or run on a powerful local machine for $0.

🎉 Bottom Line

Every data source in this project is FREE.

• Census data: FREE ✅
• Meeting datasets: FREE ✅
• Public websites: FREE ✅
• Software: FREE ✅
• Total cost: $0 ✅

The only potential costs are:

1. Optional AI summarization (~$0.01/meeting with GPT-4o-mini)
2. Optional cloud hosting (pay-as-you-go for compute)
3. Your time (engineering effort)

But all DATA access is completely FREE and always will be, because it's public government information required by law to be accessible.

No paid services. No vendor lock-in. No API subscriptions. Just free, public data. 🎯
