`params(subspace, key)`	The value of the parameter `key` in `subspace`, as a JSON string. For example, `params("staking", "MaxValidators")` returns the maximum number of validators.

The call reverts if subspace or key is empty, or if subspace does not exist. If key does not exist in subspace, the call returns an empty string.
