Builder spotlight! 🚨🧵

@bagelandlocks_ wanted to make sure he was betting the best price, every single time.

So? he fueled the idea using our API.

Now it's in our marketplace, and you can bet through it too!

[Bagel & Locks @bagelandlocks_]

i used six prediction market apps. Six logins, six balances, and a price that was a bit different on every one.

Using @OpenMarketsAI's API, i could get all of it on one screen.

Here's how it works, and what YOU could build on it. 🧵
