Equities

Metric History

GET/v2/equities/metrics/history

Returns one statement-derived metric (ratios, margins, growth and every *_ttm name) as a series of points, one per fiscal period end, newest first. Suppressed periods are returned as explicit null points with a reason instead of being omitted, so point counts stay stable for mirrors; see the Metric History guide for basis, vintage and TTM-overlap semantics.

Included in: Startup, Pro, Growth.

Parameters

Required: one of symbol, isin, for example symbol=AAPL.

Name	In	Type	Required	Description
symbol	query	string	one of symbol, isin	Stock ticker symbol (e.g., `AAPL`, `MSFT`, `GOOGL`). Provide exactly one of symbol or isin. Example `AAPL`
isin	query	string	one of symbol, isin	ISIN code (e.g., `US0378331005`). Provide exactly one of symbol or isin. Clear the symbol example before using an ISIN.
name	query	string	yes	Metric name. Discover valid names via GET /equities/metrics/names. Example `roe_ttm`
basis	query	string	no	Reporting basis. Defaults to TTM for *_ttm names, FY otherwise. One of `FY` `Q1` `Q2` `Q3` `Q4` `H1` `H2` `TTM`
vintage	query	string	no	MR = most recent restated statements. AR / as_of point-in-time replay is not yet enabled. One of `MR` Default `MR`
from	query	string (date)	no	Earliest period end (inclusive).
to	query	string (date)	no	Latest period end (inclusive).
provenance	query	boolean	no	When true, each point carries a provenance block (knownAt, restated, and the vendor's acceptedDate/filingDate claim). Empty while ledger coverage has not begun for the security. Default `false`
changedSince	query	string (date-time)	no	Incremental sync. Returns only points whose value changed at or after this ISO-8601 timestamp. Pass the `syncCursor` of the previous response; points upsert on periodEnd, so re-pulling an overlap is harmless.
