evaluate_symbol

Return the bottom/top verdict for one Seoul district apartment market (25 districts). Accepts Korean (강남구, 강남) or romanized (Gangnam, Nowon, Mapo …) names. 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. Price = volume-weighted median per pyeong (KRW 10k) from official MOLIT closed transactions. 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.

pitch

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

scan_bottoms

Check your subscription status & terms (FREE), or activate the monthly plan: call with activate:true to receive the $50 x402 payment challenge, sign it, and retry — that buys 30 days of unlimited calls and returns your X-SUB-KEY token (pass it as a header to skip per-call payment). Until you subscribe, signal calls are $0.01 each. Optionally pass your ERC-8004 agentId to link it.

Argument	Type	Description
agentId	string	Optional ERC-8004 agent id to link to this subscription.
activate	boolean	true = request the $50 subscription payment challenge (402) to sign & retry.
