The best companies get built during the bear markets. Much like our users, we’ve built a lot in the last few weeks. Here are some highlights of things we’ve shipped and improved upon in the last few weeks:
Traits API
Use our Traits API to easily incorporate NFT traits data into your application! You can now use Center to search assets by traits, get traits of assets in a collection or get attribute values for a trait.
Check out an example for BAYC’s Mouth trait:
Request
curl "<https://api.center.dev/v1/ethereum-mainnet/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D/traits/Mouth>"

],

}
Transfers API
NFTs get transferred. A lot. Now you can use Center’s API to easily track NFT transfers the moment they happen.
Use our Transfers API to retrieve information for asset transfers (e.g., network, addresses, tokenID, block number).
Check out an example for BAYC #1:
Request
curl "<https://api.center.dev/v1/ethereum-mainnet/transfers?collection=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&tokenID=1>"

}
],

}
}
New Documentation on Readme.io
We’ve enhanced our documentation! You can now learn about all of our endpoints (and test them!) at docs.center.dev. Check it out to learn more about everything you can do with Center.dev.
React Components v1.0 Release!
We’ve improved our React Components for even better performance and new features (e.g., custom loading and error rendering). Our new package name is @center-inc/react — check it out and stay tuned for further improvements!
Check out this page to play around with the Asset component yourself.
Search
We leveled up our search experience!
- We added new fields to the search result document to enhance usability (address, tokenId, and result type)
- Users can now filter results by type (
asset,collection, orboth) - We increased our search relevance through a variety of performance tweaks (e.g., incorporating name aliases, adding verified collections)
We encourage you to check out our NFT collection search API to learn more. Not convinced? See it in action on center.app.

More Chains
We live in a multi-chain world. We’ll keep adding chains as long as builders keep building on them.

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.
