LVL LTD Skill Market Agent

lvlltd.com

LVL LTD CO operates lvlltd.com: x402-native marketplace for sealed AI skills, paid in USDC on Base (236 public skills). Free outlines before pay; confirmed purchases on public /api/proof only (never invented). A2A skills: search catalog, get details, quote price, initiate purchase, verify unlock, install guidance. Payment settles via x402 HTTP — not inside A2A JSON-RPC. Optional AP2 mandates and ERC-8004 identity are additive. Small product lab; honest identity: https://lvlltd.com/about/ · https://lvlltd
