Stopped workingSubscribe to Alchemy APIShare
On September 30, 2026, the /nft/v2/{id}/invalidateContract endpoint was sunset to streamline and improve the NFT API. Requests sent to this endpoint fail since that day. This change affects all callers attempting to use the route on eth-mainnet.g.alchemy.com.

/nft/v2/{id}/invalidateContract
What to use instead of these calls
Drop the call to /nft/v2/{}/invalidateContract. Instead, POST /nft/v3/{apiKey}/refreshNftMetadata remains available.
In Alchemy API's words
To streamline and improve the NFT API, Alchemy is sunsetting a small set of redundant endpoints — both their V2 and V3 versions — on September 30, 2026 .
