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

  • Rewards/loyalty programs

  • 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
