x402stock.xyzDescribe 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

Discovery comes from configured registries. Endpoint checks record responses, not task success. Older snapshots retain less detail. Customer usage, commercial terms and task evaluations require additional evidence.
