Get Pool and OpenBook Market Info

Fetch pool and OpenBook market info required for building a swap transaction.

Liquidity pool info alone is not enough to execute a swap transaction on Raydium. You also need the OpenBook market info as well. The pool provides some keys fields, such as marketId and marketProgramId, which we would use to fetch the further necessary details.

Our aim is to get the same information which we get from Raydium's Pool API. You can directly use this API as well. The issue is that this API returns 250+ MB of data, which you have to manually filter for required info. On top of that, new pools take some time to reflect here.

With Shyft's GraphQL API, you can get the same information in the lowest latency possible. Copy and run this code directly in Replit to see it in action.
