Solidity Alchemy API getNFTsForcontract only return 100 results

Question

    async function main() {
  // Contract address
  const address = "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D";

  // Flag to omit metadata
  const omitMetadata = false;

  // Get all NFTs
  const { nfts } = await alchemy.nft.getNftsForContract(address, {
    omitMetadata: omitMetadata,
  });

  let i = 1;

  for (let nft of nfts) {
    console.log(`${i}. ${nft.rawMetadata.image}`);
    i++;
  }
}

main();

I used above code to get all NFTs ipfs info from one collection But it only return 100 as in the result. This is the bored ape nft contract address I provided, it should have returned 10K items. What did I miss here? thank you
