What are compute units?
Compute units are how we measure request volume. Each endpoint consumes a specific number of compute units per successful request. This number is generally one — meaning that one request is equal to one compute unit.

However, some requests are more complicated. We support batching, and also have endpoints that return a variable sized response depending on the request. For these endpoints, we scale the number of compute units so we can accurately reflect the amount of resources they are consuming.

How should I estimate how many compute units I need?
You can look at our compute unit table to see how many compute units each endpoint consumes.

What is the difference between "Center API V2" and "Center API V1"?
The Center API V2 is the next-generation crypto API — we took everything our users loved about V1 and built on it to create the fastest, most accurate and most powerful API available anywhere. Our V2 endpoints are faster, more accurate, more flexible and more powerful than V1.

Using the API

How can I render NFT media with Center?
Center's best-in-class renderer allows you to include a wide range of NFT media in your application.

You can render any of the media associated with an NFT, including audio and video files. If there are multiple media files associated with an NFT, you can view all available media files using the List NFT Media endpoint or Show NFT Metadata endpoint. Simply specify the key for the desired media file in the mediaPath parameter of our renderer to render the proper media file.

Center also makes it easy to customize media types and dimensions. You can specify the exact dimensions you would like as part of the call, and we'll return exactly what you are looking for. You can also specify file types (.jpg, .png and .gif) and we'll transform the media for you.

What is safe rendering?
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.

With the Center, users can specify precise file types before rendering (.png, .jpg and .gif). The Center Renderer will rasterize the media to convert it to the desired file type, which will remove any malicious elements so that users are protected.
