# Ocean Primitives Ocean Primitives are a type of primitive designed to interact with the Ocean contract. At a minimum, they must implement the `computeOutputAmount` and `computeInputAmount` functions from the `IOceanPrimitive` interface. Their main role is to compute exchange rates between an input and output token. This can take many forms, depending on the primitive. For instance, in the context of an AMM primitive, the primitive is tasked with determining the swap rate. Conversely, the Ocean's responsibility lies in updating the relevant balances: of the users, the AMM, and any other associated primitives. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.shellprotocol.io/deep-dive/important-concepts/ocean-primitives.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
