# OSM ### **Purpose** It ensures that new price values propagated from the Oracles are not taken up by the system until a specified delay has passed. ### Key Responsibilities * Periodically feeds a delayed price into the system for a particular collateral type. ### Key Methods * `peek()`\ Returns the current feed value and a boolean indicating whether it is valid. * `read()`\ Returns the current feed value; reverts if it was not set by some valid mechanism. * `peep()`\ Returns the next feed value (i.e. the one that will become the current value upon the next `poke()` call), and a boolean indicating whether it is valid. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
