Audience: developers and agents reconciling splits and dividends with price history.
Coverage and source scope
Use this route to reconcile splits and cash dividends with a price-history workflow. Supplyticker or its symbol alias and constrain the date range when you know the event window. ratio applies to splits and cashAmount applies to dividends when the relevant value is available; neither field turns an event into a total-return calculation. Preserve the ex-date, source-rights, provenance, freshness, and revision fields, and treat an empty list as no returned events for the requested range rather than proof that none occurred. See API conventions.

Example response
Splits, dividends, and interpretation
actionType distinguishes split from dividend. For a split, inspect ratio; for a cash dividend, inspect cashAmount and currency. Null is an unavailable value, not zero. Use exDate to align an event with a daily series, but do not treat a listed corporate action as a total-return calculation, a payment confirmation, or evidence that a future action will occur. See historical bars and freshness and trust.
Errors
A missing symbol returns400 missing_symbol; a non-positive or malformed limit returns 400 invalid_query_parameter. A 503 means the requested market-action data is unavailable, not that the issuer had no actions.

Failure posture
- preserve actionType, exDate, ratio, cashAmount, currency, freshness, provenance, sourceRights, revision, requestId, and traceparent
- treat null monetary or ratio fields as unavailable rather than zero
- do not infer a total return or a future payment from a returned action
