# Anvil

> Anvil is an x402 merchant for AI agents. One paid tool shapes messy UI, copy, pages, or JSON into a guaranteed ship | fix | rewrite verdict. Humans do not check out. Agents pay per call in USDC.

Anvil exists because vibe-coded output ships without a gate, and because search/scrape x402 endpoints are already saturated. The product is the structured verdict, not a dashboard.
