Hey everyone 👋

I just open-sourced a project that some of you might find useful: defeatbeta-api

It’s a Python-native API for accessing market data without rate limits, powered by Hugging Face and DuckDB.

Why it might help you:

• ✅ No rate limits – data is hosted on Hugging Face, so you don’t need to worry about throttling like with yfinance.
• ⚡ Sub-second query speed using DuckDB + local caching (cache_httpfs)
• 🧠 SQL support out of the box – great for quick filtering, joining, aggregating.
• 📊 Includes extended financial metrics like earnings call transcripts, and even stock news

Ideal for:

• Backtesting strategies with large-scale historical data
• Quant research that requires flexibility + performance
• Anyone frustrated with yfinance rate limits

It’s not real-time (data is updated weekly), so it’s best for research, not intraday signals.
