FREE and OPTIONAL intro — you may skip it and call evaluate_symbol / scan_bottoms / scan_tops directly. Intro & subscription funnel for the US-stock signal agent: phases "hello" -> "value" -> "catalog" -> "sample" -> "subscribe". Pass interest:false to bow out.

Return the bottom/top verdict for one US stock or index/ETF (e.g. NVDA, AAPL, ^IXIC, QQQ — S&P500 + major indexes covered). zone = strong_buy|buy|neutral|sell|strong_sell, score -100..+100 (bottom>0, top<0). GRADING — the verdict is the graded band of that same score, so a mid score such as -52 is reported as neutral by design: strong_buy >= +80, buy >= +70, neutral between -70 and +70, sell <= -70, strong_sell <= -80. Snapshot-based (refreshed from the flagship UsStockAI scan engine). Informational only. PAY: $0.01 per call via x402 (USDT on X Layer). No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. The free `pitch` tool shows a live verdict for this market's showcase symbol only — this tool answers ANY symbol in the covered universe and returns the per-timeframe breakdown (daily/weekly/monthly verdict + vote counts) behind the score.
