Server instructions

Chart Library is a free market-state research library. Read-only tools, choose the tools needed for the question. Market state needs no preceding search. get_company_file(symbol, as_of?) reads the same company research and models shown on /r/SYM. get_company_status(symbol) reads current monitoring separately from immutable model data. list_coverage() finds names and research status. Keep reported facts, company guidance, desk assumptions and historical analog bands separate. market_state(symbol, date?) gives a completed-session state, historical analogs, outcome ranges and transition memory in one call. Omit date for the latest built session; this does not mean real-time data. daily_note(date?) reads the published daily research, selection rule and settled tally. research_quality() reads the published calibration receipt. That receipt applies only to the method and population it names, not automatically to market_state's empirical excess-return ranges. search_research(query, kind?) finds publications. Search metadata is not a source read. Copy documents[section].read_arguments into read_research; follow content.next_read for further chunks. Read available guides and related findings before making claims, and cite full version hashes. Agent protocols are labeled proposed until evaluated. Keep the response's dates, sample sizes, provenance, missing values, warnings and informative receipts. Historical frequencies are not buy/sell recommendations. Do not invent evidence or turn an empty or weak result into a confident claim. Research access is free; service limits and data terms apply. Existing advanced tools remain callable for compatibility but are not the public getting-started menu. For custom integrations, larger studies or building a product, contact Graham at graham@chartlibrary.io or https://chartlibrary.io/developers#build.

Known tools 13

get_company_file

One covered company's living research file (company_file.v1): business, three drivers, the last eight fiscal quarters from SEC XBRL with provenance on every number, the desk's own estimates and revision log, the thesis and what changes it, the market-memory bands or an explicit coverage 'none', published notes, and the scorecard.

Inferred read-only

get_company_status

Current monitoring alongside the immutable company file.

Inferred read-only

get_company_revisions

Browse immutable published versions, reasons and pinned JSON/CSV links.

Inferred read-only

compare_company_revisions

Compare facts, assumptions, scenarios and thesis between immutable revisions.

Inferred read-only

run_company_scenario

Calculate a temporary scenario from 1-20 assumption cell IDs and numerical values in their published units.

Inferred read-only

check_company_forecasts

Compare frozen revenue forecasts with reported results.

Inferred read-only

compare_company_history

Two to six companies, one quarter end (YYYY-MM-DD), USD history and provenance.

Inferred read-only

list_coverage

The research hub's coverage universe: clusters and symbols, with each symbol's company-file revision, as_of date, whether a compiled file exists, and skeleton=true when the authored half is empty.

Inferred read-only

market_state

One call: completed-session state, tape, historical analogs, outcome ranges and transition memory.

Inferred read-only

daily_note

Read the published daily research, its selection rule and settled-note tally in one call.

Inferred read-only

research_quality

Read the published five-session calibration receipt; no arguments or earlier tool call needed.

Inferred read-only

search_research

Find published studies, Casebook and agent protocols by keyword.

Inferred read-only

read_research

Read a publication ID returned by search_research, preserving its evidence.

Inferred read-only
