Balance sheet, income statement and cash flow — four sources, one shape

{ "entity": { "name": "SAP", "isin": "DE0007164600", "country": "DE" }, "source": "sec.dera", "periods": [ { "end": "2025-12-31", "type": "FY", "currency": "EUR", "metrics": { "revenue": 34176000000, "net_income": 3086000000 } } ] }

What you can do with it

Pull ten years of metrics without knowing XBRLOne call, one flat list. No tag vocabulary, no taxonomy knowledge required.

Put up to 25 companies side by sideEvery row names its source, accounting standard and currency — so it stays visible what is comparable and what is not. We deliberately convert nothing.

Render a complete statementperiods is the table header, lines[].values are the cells. Identically shaped across all sources.

Check up front what actually existsThe coverage call names the data pools, the time range and the metric coverage before you build the real query.

Why we built it this way

Four data pools had four incompatible shapes: values sometimes a list, sometimes a scalar, sometimes a year map. Periods sometimes 20251231, sometimes ISO, sometimes just a year. German reports had to be multiplied by a factor first. Comparing two companies meant writing four parsers.

We settled on seven rules and applied them everywhere. One is easy to miss: European reports state the period end exclusively, so one day late. Without that correction no European period ever lines up with an American one — and every fiscal year carries the wrong label.

Values in the lines stay as reported. Unification happens only in the metric rollup, and there in a way that makes revenue minus cost of revenue equal gross profit across every source.

Improvements

Four data sources now return the same shape — US, Europe, Canada, Germany

European reporting periods were off by one day and are now correct

German values come back absolute, no longer in units of millions

Currency is now detected for US securities — it used to come back empty
