​

What is Pinata?

Pinata makes file uploads easy for developers who need fast and zero-setup soltuions. We’ve seen the struggles with solutions like S3 for file uploads, and we knew we could make it better Our primary product, the Files API, makes it as simple as one line of code to upload a file:

const upload = await pinata.upload.file(file)

Retreiving files is just as easy!

const signedUrl = await pinata.gateways.createSignedURL({
 	cid: "bafkreib4pqtikzdjlj4zigobmd63lig7u6oxlug24snlr6atjlmlza45dq",
	expires: 30,
})

Built on years of experience with IPFS, Pinata has scaled companies to serve high volumes of requests and bandwidth, as well as developers who are just starting out. Next time you think you need S3, consider spending less time and go with Pinata.

​

Challenge Statement

Pinata makes file storage and retrieval incredibly simple, freeing you from the complexity of AWS S3 setups and tricky IAM policies. We’re challenging teams to unleash their creativity and build the most unique, game-changing full-stack application using only Pinata—no external databases allowed. Show us how you can push boundaries and create something that truly stands out!
