# /nft/v3/{}/isHolderOfContract stops working

Calls to /nft/v3/{id}/isHolderOfContract on Alchemy API stopped working on September 30, 2026.

Alchemy removed the /nft/v3/{id}/isHolderOfContract endpoint on September 30, 2026. Calls sent to this endpoint fail since that date. The change was announced on August 18, 2026, as part of an effort to retire a small set of redundant NFT API endpoints.

## What to use instead

Call GET /nft/v3/{apiKey}/getNFTsForOwner filtered by contract address instead.
