Sill sits between AI agents and your store. For every agent interaction it answers three questions:

  • Identity — which agent is visiting.
  • Intent — what it is trying to do, and whether your rules allow it.
  • Proof — a signed record of what happened, which anyone can verify.

Sill has two modes:

  • Discovery — install the script tag, the WordPress plugin, the Shopify app or the Cloudflare Worker. Sill identifies and logs AI-agent traffic and publishes a signed agent card, an MCP server and an ai-catalog.json for your site, so agents can find out what your store offers. Discovery is live.
  • Transactional — agents send signed orders, Sill checks them against your guardrails, payment goes through Stripe, and every decision is recorded and signed. Transactional is in early access on the Stripe rail.

Sill never holds funds. Stripe holds the card, authorizes the charge, settles and pays out. Sill issues the signed authorization and the audit record.
