# SML OmniPost

> One post → native, validated posts for 14 social platforms. BYOK web app for creators and an x402-paid API + MCP server for AI agents. Built by Script Master Labs LLC (SDVOSB, Kinston NC).

OmniPost rewrites a single source post into platform-native versions for X, Threads, Instagram, TikTok, YouTube, LinkedIn, Facebook, Pinterest, Reddit, Discord, Telegram, WhatsApp, Google Business Profile and Bluesky. Every variant is checked against verified platform limits and auto-repaired. It never invents facts, prices or claims.
