Welcome to the inaugural OpenSea Developer Newsletter!
In this first edition, we’re sharing a recap of recent news and updates to the OpenSea Developer platform - including our API, SDK and developer events.
Let’s dive in!
On May 5th, we launched a beta version of the Stream API, a new websocket-based service that enables developers to receive events as they occur across our marketplace.
We’ve built the Stream API to better support a range of use cases that rely on dynamic data, such as price fluctuation, listings, bids, and ownership changes. Instead of polling for updates, you can subscribe to receive events as they occur - whether for specific collections or globally across the entire OpenSea marketplace.

On April 26, 2022, we began to require the
side parameter to be included in all requests to the
/wyvern/v1/orders endpoint. This parameter is used to filter the response to either buy or sell orders and was previously optional. Moving forward, requests will fail if they don’t include this parameter. Learn more here.

Check out our guide to learn more about how Solana works on OpenSea.
OpenSea recently teamed up with Replit to host the Hello NFT World Hackathon. Check out the BUIDLs and winners in the Hello NFT World Hackathon Recap.
