Is plainquant live?

Yes — it answered the hub's last check (checked 9h ago). It answered 100% of checks over the last 30 days.

Is plainquant free to use?

Yes — the hub reached it with no key and no payment.

What tools does plainquant have?

4 tools: event_study, index_move_study, list_events, check_stocks.

Is plainquant safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

• list_events open 9h ago

  The events PlainQuant has history for (Fed decisions, CPI, jobs reports, US elections, quarterly options expiry, market drops), with ids, names in English and Chinese, and aliases.

• event_study unknown 9h ago

  For each past occurrence of the event, the move of the market (market: US = the S&P 500 via SPY, the default for US events; HK = the Hang Seng Index, from its first close after the news; 'measured' in the answer names it) 2 weeks, 4 weeks and 3 months later (fractions: 0.037 = +3.7%), plus median, share up, worst and best beside any window of the same length. With too few occurrences only the list is given. Give symbol (a ticker or company name of the measured market) to measure that one stock's own price, dividends included, instead of the market (QQQ for the Nasdaq-100). Use for questions like 'what happens to stocks after a midterm election / an FOMC meeting', 'what did AAPL do after CPI' or 'what did Hong Kong do after the Fed'.

• index_move_study unknown never probed

  Like event_study, for a move of an index found in our prices: index SPY (S&P 500), QQQ (Nasdaq-100) or HSI (Hang Seng Index) moving pct percent (signed: -10 = a fall of 10% or more) within days trading days (a fall without days = from its high). Use for 'what happens if the Nasdaq drops 10% in two days' or 'what does Hong Kong do after the S&P 500 falls 3% in a day' (market HK).
