Server tool list (15)
Raw names from tools/list. Only developers need these.
| get_composite | Everything the platform knows about one ticker in a single record: the cross-signal consensus, each contributing dimension with its direction and provenance, and risk flags. Start here for any question about a specific company. |
| get_demo_composite | A single fixed demo ticker, callable without an API key, so the data shape can be inspected before signing up. Returns only the demo ticker regardless of input. For real tickers use get_composite, which requires a free key. |
| get_evidence | The primary documents a ticker's signals were derived from — insider Form 4s, Congressional disclosures, institutional holdings and macro series, each with the filing it came from. Use this to cite a claim rather than assert it. Paid keys only, and slower than the other tools because it is computed on demand. |
| get_house_rating | The platform's own buy/hold/sell rating for a ticker, with the reasoning behind it. A judgement about the stock, not a recommendation to any reader. |
| get_consensus | Whether the independent actors this platform tracks — insiders, Congress, institutions, the model — agree on one ticker, with the per-dimension breakdown that produced the verdict. |
| rank_consensus | The names where independent actors agree most strongly, ranked. Use this to find candidates rather than to check one you already have in mind. |
| screen | Filter the whole equity universe and return matching tickers with their scores. The bulk discovery tool: use it for questions of the form 'which companies have X'. To rank by cross-signal agreement instead, use rank_consensus. |
| list_insider_trades | Corporate insider buys and sells from SEC filings, newest first, each linked to the filing it came from. |
| list_congress_trades | Disclosed House and Senate trades, newest first, each linked to its disclosure. Committee overlap is reported as oversight, never as an accusation. |
| list_positioning | How large holders are positioned, newest first. Net figures can reflect hedges and cannot be read as a directional view on their own. |
| get_historic_moves | The historical distribution of 5-day and 1-month returns for a ticker, sampled over the last 5 years: mean, standard deviation, percentiles, a histogram, and the worst drawdowns with their dates. Use it to say whether a move is unusual FOR THIS NAME rather than in the abstract. Every number is a fraction: 0.0821 means 8.21%. |
| list_equity_perp | Funding rate and open interest for the ~51 US single names listed on a 24/7 perpetual futures venue, ranked by notional. This is the ONLY source here that moves outside US market hours, so it is what to check overnight and at weekends. High positive funding means longs are paying to hold — crowded, squeeze-fragile. The mark price is a venue mark, NOT the stock price. |
| get_equity_perp | Funding and open interest for a single name on the 24/7 perpetual venue. Most tickers are NOT listed there — only about 51 of ~5,400 — and a 'not listed' answer means no venue coverage, never that positioning is flat or zero. |
| search_tickers | Resolve a company name or partial symbol to tickers the platform covers. Use this first when the user names a company rather than a symbol. |
| get_signal | A whole-market gauge rather than a per-company one. 'macro' is the market-regime read, 'energy' the macro energy balance, 'crypto' crypto positioning and funding. Use these for the backdrop a single name is trading against. |
