Integration details

Description

See the reasoning behind an investor's stock thesis and what changed. BeliefState brings attributed beliefs, dated evidence, catalysts, risks, and invalidation conditions into your AI chat. Check available company coverage, request a research brief, or inspect a belief and its revisions with source citations. Filter records by company, investor, or time to compare the available views. Results keep missing evidence and limited coverage explicit. BeliefState returns research; it does not place trades or provide personalized investment advice.

Tools

18 tools agents can invoke

Compare two cited investment cases for support, contradiction or dependency, including explicit unknown and unrelated outcomes. Optional comparison_focus selects a public research topic within both complete cases; the result applies to that topic only. Shared-source provenance does not establish research independence. Uses account allowance or prepaid credit.
compare_beliefs
Search the SEC-registered US company directory by ticker or name and check direct research availability. Free.
search_companies
Find released companies, industries, themes and other research subjects by name or kind. Uses account allowance or prepaid credit.
search_entities
Inspect cited relationship paths within one investment case. Preserves stated links, engine inferences and unknowns. Uses account allowance or prepaid credit.
get_belief_relationships
List dated investment ideas for a requested inventory or filtered research on one ticker or subject. Investor, direction and time filters are optional. An ordinary overview uses get_brief; listing the same research afterward is unnecessary unless the user needs additional cases. Uses account allowance or prepaid credit.
get_beliefs
List cited charts and tables for one investment case or context assessment. Uses account allowance or prepaid credit.
list_research_visuals
Open a dated engine context assessment and its permitted evidence. Engine analysis is separate from an investor's stated view. Uses account allowance or prepaid credit.
get_context_assessment
Read a requested complete investment case or evidence beyond a brief, with risks, conditions and coverage gaps. An ordinary library overview can use get_brief without opening each case. Use paragraph_index only when it appears in the returned investment_case; follow support/text offsets. Records without investment_case return their full claims and citations without paragraph selectors. Uses account allowance or prepaid credit.
get_belief
Read one cited chart or table, including its regions and paginated exact rows or data points. Uses account allowance or prepaid credit.
get_research_visual
Read evidence-linked Catalyst objects with qualified current status or explicit unknowns. Filter one ticker, entity, Belief or released corpus by person, source, publication dates or status. Current briefs include pending and unassessed attached catalysts; met, missed and superseded records remain available here. Follow signed pagination with identical filters. Uses account allowance or prepaid credit.
get_belief_catalysts
Read evidence-linked Risk objects for exactly one ticker, entity, Belief or explicit released corpus. Filter by person, source, publication dates, status or severity. Unknown assessments remain unknown; an empty high-severity filter does not prove no material risks. Current briefs include attached open risks, continuing materialized risks and separately marked unknown concerns; no implicit age or severity cutoff. Follow signed pagination with identical filters. Uses account allowance or prepaid credit.
get_belief_risks
Explicitly refresh missing or stale market data for one current company or subject, then return its research brief. Uses account allowance or prepaid credit.
refresh_market_data
Research a company, ETF or subject. ETF briefs connect dated fund holdings to available company research in one read, with weights, citations and missing coverage. Stock overviews provide selected cited views; complete cases, later assessments and current prices appear when available. Use overview first and get_belief for a selected complete case. Oversized full MCP reads return a labeled overview. Missing or stale requested inputs refresh within bounds; historical reads preserve their cutoff. Uses account allowance or prepaid credit.
get_brief
Read a mixed, ordered change journal: author-view revisions, distribution changes and calculated publication outcomes are separate domains with distinct clocks. Use belief_id for changes to one case and inspect each event's domain. Use get_brief for a current synthesis; continuation is for requested journal history or polling. Uses account allowance or prepaid credit.
get_belief_changes
List direct company research coverage and counts. ETF holdings coverage is available through get_brief even when the ETF is absent from this company list. Free.
get_tickers
Find investment ideas by thesis, topic or trade setup, with cited matching passages. Uses account allowance or prepaid credit.
search_beliefs
Apply up to eight hypothetical condition assumptions to a case's recorded scenario model. Does not alter evidence or predict the investor's response. Uses account allowance or prepaid credit.
evaluate_belief_scenario
Read the connected account's actively tracked tickers. Free.
get_tracked_tickers
