Describe a screen in plain English via `?q=` (e.g. 'oversold large caps up today on high volume'). An LLM parses it into a filter, screens the entire US market, optionally confirms oversold/overbought with RSI, and returns a ranked shortlist with a one-line rationale per name. No need to know the filter schema or run the enrichment loop yourself. From x402stock
