What data it sees

Do you need an account

No: the server works without sign-in

Qualitative equity screening for 3,600+ listed companies. Baseline scores business quality, moats, pricing power, switching costs, management and risks using fixed prompts applied identically across the universe, and every score carries a written analyst-style rationale you can check against the filings.

Use it to screen on any combination of scores (for example pricing power 4 or better and barriers to switching 4 or better), pull the rationale for a company and field, list the available fields, and manage watchlists.

Scores run 1 to 5, where 5 is most favourable on every field, including Risks (5 means risk is low and well contained). 0 means no data. Baseline screens and surfaces candidates; it does not forecast returns or give investment advice.

Sign-in is OAuth with a Baseline account. Free plan with 10 company opens; paid plans from $39/month. Built by A5 Labs, London.

Server tool list (11)

Raw names from tools/list. Only developers need these.

baseline_catalogList the Baseline research catalog: every scored field (with hierarchy) and the sectors covered. Call this first to learn valid field and sector names for the other tools.
baseline_tickersList stock tickers known to Baseline, with pagination and optional exact ticker/country filters. Listings cover enabled-for-Baseline stocks (matching the catalog's sector counts); exact ticker lookups also match disabled rows. Pass include_disabled=true to list everything.
baseline_resultsFetch a stock's full Baseline results — score, summary AND the complete result document (rationale + analysis matrices), exactly what opening the result in the Baseline app shows. Ticker in SYMBOL.COUNTRY format, e.g. MSFT.US. Only score/group fields carry a score; data fields (e.g. Market Cap) return their datum in value/value_array with score null — Market Cap value is USD (see value_currency). Present the document content to the user, not just the score. Pass include_documents=false only for a quick scores-only glance.
baseline_rationaleFetch the full written research rationale behind a stock's Baseline scores — the analysis and evidence, not just the number. Use when the user asks WHY a stock scores the way it does, or wants the underlying research. Each rationale carries its generation date (updated_at) — treat figures as of that date, not live. Ticker in SYMBOL.COUNTRY format; up to 5 fields per call (rationales are long).
baseline_query_by_scoreFind stocks whose score on ONE Baseline field matches a condition, optionally narrowed by sector and/or country. For multiple conditions at once use baseline_screen.
baseline_screenStructured screener: AND-combine up to 5 score conditions (e.g. Business Quality >= 4 AND Pricing Power >= 4), optionally filtered by sector/country. Returns compact rows with every requested score per stock — the best tool for questions combining several criteria.
baseline_watchlistsList the user's Baseline watchlists with their stocks.
baseline_create_watchlistCreate a new Baseline watchlist for the user. Names are unique per user.
baseline_delete_watchlistDelete one of the user's watchlists (and its stock entries). Irreversible.
baseline_watchlist_add_stockAdd a stock (SYMBOL.COUNTRY, e.g. MSFT.US) to one of the user's watchlists.
baseline_watchlist_remove_stockRemove a stock (SYMBOL.COUNTRY) from one of the user's watchlists.
