- `page` integer, nullable — The desired page to return from the query
- `pageSize` integer, nullable — The amount of items to return from the query, defaults to 10, and must be <= 100

## Response `200`

Returns a list of Boosts

- object
  - `signatures` object[], required
    - `id` string, required — A hexadecimal string representing the function or event signature. This string will always start with 0x, and end with the 32 byte signature. If selector is a function, then the 4 byte signature will be left padded with zeroes to 32 bytes.
    - `textSignature` string, required — The human readable function or event signature from the smart contract
    - `abiItem` object — The JSON of the underlying contract's function or event ABI item
