# Intro

Looking to build a bespoke experience with NFTs? This the set of APIs you want!

{% hint style="info" %}
Email us at <help@usewinter.com> to get your API key!
{% endhint %}

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
