Threads keyword search + reply to discovered posts

I'd love an endpoint to search public Threads posts by keyword (like the existing Reddit and X/Twitter search) and reply to the ones I discover. Meta's Threads API allows replying to others' posts when they're found via keyword search. My use case is surfacing relevant posts and replying with helpful product recommendations. Right now Zernio only supports replying to comments on my own posts, so a Threads search + reply flow would unlock this.
