Announcing: NFT Rarity API

Access NFT rarity data through

By Center 2 min read

We are excited to announce that we have added support for NFT rarity through

Builders can now use Center's API to easily retrieve rarity data for any NFT. Using the Get Asset Rarity endpoint, simply provide the blockchain, collection address and tokenID to retrieve:

  • score: Normalized rarity score (based on the OpenRarity standard) that reflects how rare a particular NFT is within its collection. Rarer NFTs receive higher scores.
  • rank: Rarity ranking for the NFT within its collection (with the most rare being ranked 1)
  • total: Total number of NFTs within collection

Check out an example below for BAYC #1:


curl --request GET \
     --url \
     --header 'X-API-Key: test' \
     --header 'accept: application/json'


  "score": 1.0568741465396123,
  "rank": 3256,
  "total": 10000

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.
