Get Screener

Stock screener.

• Unauthenticated: returns limited fields (ticker, company_name, sector, score, mos_pct) for top 50 stocks.
• Authenticated with active subscription: returns full screener response (existing behavior).

Full response logic:

1. Fetch all scored rows from screener_cache (save_score not null).
2. Compute the 90th-percentile score threshold — exposed as count so the UI can show pool size for context.
3. Return the top 20 stocks by overall_score (falls back to save_score) from the top-decile pool. Admin-curated weekly picks override when present.
