We're pleased to announce that our V2 renderer supports "Safe Rendering", which enables our users to remove malicious elements from NFT media before showing them in their applications.
Malicious NFTs have unfortunately become an attack vector for hackers looking to drain wallets. The precise attack can vary – but often take the form of a surprise airdrop. When users view the airdropped NFT, the NFT media triggers a pop-up prompting users to connect their wallet. If granted, hackers drain the user's wallet.
These types of attacks can be major problems for applications that allow users to view NFT media. With the Center API V2, you can now protect your users from these attacks.
With Center's next-generation renderer (part of our new V2 API), you can render NFTs in "safe mode":
Making this change is as easy as adding the desired extension to the end of your API request!
This request will render the original media as it exists on-chain:
https://api.center.dev/v2/ethereum-mainnet/{NFTAddress}/nft/{tokenId}/render/original
This request will convert the media to a .jpg file (see ".jpg" at the end of the request), removing any malicious elements in the process:
https://api.center.dev/v2/ethereum-mainnet/{NFTAddress}/nft/{tokenId}/render/original.jpg
This works for .jpg, .png and .gif! Check out how easy it is to transform media to different file types:

What is an NFT API?
Building NFT-related applications from scratch is complicated. It might require indexing multiple chains, ingesting vast quantities of data, and meticulously building low-level infrastructure to ensure all of the data is processed correctly. This could take engineers months to get right before they even start building an application.
Our APIs allow builders to abstract away this complexity and focus on building useful products for end users right away— we take care of the infrastructure and low-level technical details. With just a few lines of code, builders can use our APIs for a range of use cases including NFT rendering, search and data retrieval.
