Introduction
drillr is a suite of fundamental equity data APIs for the US, China and Japan, built for investors who need to find opportunities, form ideas and go deep on them. It comes in three parts: search APIs that find companies matching a common thesis, search from filings and news based on a natural-language query, data APIs that return fundamental metrics parsable from any SEC filings, including corporate events, financials, executives, owernship, etc; and signal feeds that surface industry inflection, major events, etc. Use the whole stack or call any piece on its own. Every number is parsed by drillr from primary sources, and every reported figure links back to the document it came from.

What you get
Search
Our search engines for company discovery, filing search and news search.
- Company discovery search. Find companies from a description of what they do, including product offerings, competitive positioning, business model, etc.
“companies that make lithography equipment for chipmaking”
“Japanese factory automation and industrial robot makers”
“US companies selling weight-loss drugs”
- Filing search. Full-text search across SEC filings and Chinese and Japanese financial reports. Every hit is the passage as filed, with its section, form type and filing date, and a deep link to the official document; the filing index lists most recent filings a company has filed.
- News search. Cross-source search over company and market news, returning storylines, events and attributed claims with links to the original articles.
Data
The fundamentals, as reported and as filed — the complete set for the research and modelling that follows, from the statements through to who owns and runs the company.
- Financials. Income statement, balance sheet and cash flow statement as reported under each market’s own standard, one row per period, plus a precomputed metrics snapshot: market cap, multiples, margins, returns and growth.
- Earnings. The earnings calendar with announcement dates, EPS and revenue estimates and actuals, and structured summaries of earnings calls — highlights, guidance, risks, segments and Q&A — parsed-as-facts from the transcript.
- Events. A typed timeline of corporate events — financings, deals and agreements, executive changes, corporate actions and stake changes — with deal terms, lifecycle stage and every row linked to the filing it came from.
- Ownership. Insider holdings and transactions from Forms 3, 4 and 5, and quarterly institutional holdings from 13F filings, queryable by security to find the holders or by institution to list its positions.
- Executives. Executive rosters and annual compensation — salary, bonus, stock and option awards — taken from proxy statements, with the filing that evidences each row.
Signals
Key signals detected by drillr’s research pipeline from our data and event stacks, such as industry inflections, causal events and AI adoptions. Each is published with the evidence it rests on.
- Industry inflections. Turning points detected across many companies’ earnings calls, one row per theme, with the mechanism behind it and the companies it touches.
- Enterprise AI adoption. Concrete AI applications companies disclosed on earnings calls, one row per disclosure.
- News storylines. Causal chains of events and attributed claims, tracked across sources and returned by news search.
Company, filing and news search, financials and the earnings calendar cover the US, China and Japan. Events, Ownership and Executives are US today.
What makes it different
- Built from primary sources. Filings are taken from each market’s official channel and parsed in house. Filing search indexes the full text, not a fixed set of line items, so any figure a company ever filed is findable, and every number links back to the passage it was filed in.
- Conclusions, not relayed fields. Industry inflections, enterprise AI adoption and cross-source news storylines are conclusions drawn by drillr’s research pipeline across companies and sources, each published with the evidence it rests on.
- Structured rows out of unstructured text. Filing narratives, earnings calls, proxy tables and news carry no schema at all. drillr extracts them into typed rows — a filing narrative becomes a classified event with its type, parties and date — each with a stable id and a link to the source.
