Add Liquidity allows users to add liquidity to an Automated Market Maker (AMM) pool. Users must provide the pool ID, price tick range, base and quote asset amounts, a nonce, and a signature for authentication. Upon successful execution, the API returns the amounts of base and quote assets added to the pool.
