You guys should check out I busted my something or other vibe coding it so I feel all the pain you were describing in the space, but it certainly works now. It's the x402 gateway for @KorraFinance. There are QuantFi elements (check her track record). But her greatest value to you would be (social media sentiment x actual market price) divergence signals your agents can just pay-per-call for. Talk to @MatiGreenspan about it on a @QE4Everyone space... they get mad reach.
