I want to call a payable method using the polkadot API.

if the method would not be payable it would look like this:

const { gasRequired, storageDeposit, result, output } = await contract.query
            .method(
                fromAccount,
                {
                    gasLimit,
                    storageDepositLimit
                },
                toAccount,
                input,
                input2
            )

But how could I transfer a certain amount of native chain tokens when calling this method?

You need to add { value: valueToBeSent } as the last argument in the method

.method( arg1, arg2, { value: valueToBeSent })

This is how it works for tx call:

await contract.connect(owner).tx.createCollection(collectionMetadata, collectionMax, collectionSymbol, { value: reserveValue });

Check also if your query call method is payable. Most likely there is no charge for query.
