thanks for submitting this! just a small change and we should be good to go!

why do we need all the additional variables in the params here?

i'm thinking that we would just do
expect(actualNftContract.address).toEqual(expectedNftContract.address);

Playing with the API I saw that every element in the searchContractMetadata endpoint response has the same structure as the response from the getNftContractMetadata endpoint which was unit tested using the following function

So to keep the testing method consistent I decided to reuse the verifyNftContractMetadata function for the searchContractMetadata tests too. I can change it to test only the contract address if you want.
