# SyntheticAggregator

It allows users and consumer contracts to query information about a given derivative recipe and, internally, it is provided with some stateful logic to initialize a new financial product’s sensitive data.

### Contract functions description

**`getAuthorCommission(bytes32 _derivativeHash, Derivative memory _derivative) public returns(uint256 commission)`**

It returns the uint256 amount of fees in basis point 10000 that the derivative recipe’s author will receive for creating the given derivative recipe. Internally, the function performs stateful logic via the \_initDerivative function to check if a derivative’s data has already been initialized and, if not, it initializes it.

**`getAuthorAddress(bytes32 _derivativeHash, Derivative memory _derivative) public returns(address authorAddress)`**

It returns the address of the recipient of derivative recipe author’s fees. Internally, the function performs stateful logic via the \_initDerivative function to check if a derivative’s data has already been initialized and, if not, it initializes it.

**`getMargin(bytes32 _derivativeHash, Derivative memory _derivative) public returns(uint256 buyerMargin, uint256 sellerMargin)`**

It returns the margin of the LONG (buyer) and SHORT(seller) positions of a derivative recipe. As the margins are fully customizable, it checks the collateral requirements specified in the related derivative recipe by calling the \`getMargin\` function specified in the IDerivativeLogic interface. Internally, the function performs stateful logic to check if a derivative’s data has already been initialized and, if not, it initializes it.

**`isPool(bytes32 _derivativeHash, Derivative memory _derivative) public returns(bool result)`**

# 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:

```
