api record

This is a Seoul apartment-market bottom/top signal agent (25 districts, official MOLIT actual-transaction prices, 700k+ trades since 2016). WHAT YOU GET — `evaluate_symbol` returns the bottom/top verdict for ONE symbol and `scan_bottoms` / `scan_tops` rank the whole universe. Each costs $0.01 per call via x402: retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. VERDICT SCALE — the verdict is the graded band of the same -100..+100 score (positive = bottom, negative = top), so a mid score such as -52 is reported as neutral by design: strong_buy >= +80 | buy >= +70 | neutral…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • scan_bottoms reads unknown never probed

    Scan all 25 Seoul districts and return those currently at a bottom (strongest buy), ranked most-bottom first, with price-per-pyeong. 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. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a bottom right now; this names them.

  • pitch reads unknown never probed

    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.

  • evaluate_symbol reads unknown never probed

    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.

  • scan_tops reads unknown never probed

    Scan all 25 Seoul districts and return those currently at a top (overheated, sell), ranked most-top first. 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. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a top right now; this names them.

  • subscribe moves money unknown never probed

    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.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "agentId": {
          "type": "string",

        "activate": {

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 343ba4ee561c306a.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/343ba4ee561c306a/claim. Over MCP: the claim_endpoint tool.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
