Is there a corporate actions API for Robinhood Chain?
Yes. Robinhood publishes GET https://api.robinhood.com/rhj/corporate-actions free and unauthenticated, rate-limited to 60 requests per second with a one-hour cache. It covers 13 action types.
Each entry carries a stable id for deduplication, a type, a status of IN_PROGRESS or COMPLETED, a processDate, the token symbol, per-chain deployments, and a details object containing exactly one key matching the type.
The full taxonomy is FORWARD_SPLIT, REVERSE_SPLIT, CASH_DIVIDEND, STOCK_DIVIDEND, SPIN_OFF, CASH_MERGER, STOCK_MERGER, STOCK_AND_CASH_MERGER, REDEMPTION, NAME_CHANGE, WORTHLESS_REMOVAL, RIGHTS_DISTRIBUTION and UNIT_SPLIT.
The endpoint gives you the action. It does not give you the lifecycle — when the contract will pause, how long until the multiplier takes effect, or a stream you can subscribe to. Reconstructing that requires joining it against /assets and the onchain UIMultiplierUpdated events.
