The complete field dictionary — every standardized metric, ratio and statement line the financials engine serves, each with a plain-English definition, its statement, units, how it aggregates over periods, its formula (for ratios), the query parameters it honours, and a coverage note.

The single reference for every field the financials engine serves — the equivalent of a data terminal's field-lookup screen. It is GENERATED from the engine's own metric and ratio registries, so it is always in step with what the API actually computes: as standardization expands (more line items, more ratios), the new fields appear here automatically, and a build-time parity check guarantees the catalog can never drift from the engine or ship a blank definition. Each entry tells you the field's identifier (key), a human label, its class (kind), which statement it belongs to, its units, how it aggregates over periods (aggregation — so you know whether a trailing-twelve figure is a sum of quarters or a point-in-time balance), a plain-English definition, the formula for ratios and derived metrics (expressed in other field keys, so you can trace a ratio back to the primitives that feed it), the query parameters the field honours on the time-series and statements endpoints, and a coverage note. Filter with kind=, statement=, or metric= (a substring match on key or label). No selector and no company data — it is static reference data, served at the cheapest tier and safe to cache. Errors: 400 INVALID_PARAM for an unknown kind/statement.
