NFT Claim API
Looking to build a bespoke experience with NFTs? This the set of APIs you want!
Email us at
to get your API key!
Some common use cases we serve:
Free NFT claims
Games with NFTs
NFTs backed with physical items
Note: We do NOT help write smart contracts! These APIs are for if you already have a smart contract and you need help claiming/transferring/distributing without wanting to pay gas.
In developer speak, we help manage all the "writes" to the blockchain! Like calling a state-changing function on a smart contract.
Some common reasons why people choose to use our API:
No need to manage gas fees (Winter handles this for you)
No need to manage custodial wallets
No need to manage nonces at scale
No need to build your own infrastructure (pay as you go)
Fully whitelabeled experience
