> The commerce depth on top of the free universal gateway: PDPs rendered from the source of truth, protocol checkout (UCP, ACP, MCP), commerce intent capture, and the Answers Hub.

- **Commerce PDP capture:** 98.6% smaller PDP payload, roughly 69× less context for the same facts
  - docs/demo/agent-before-after.md — measured, never averaged with the document capture

## Why stores are moving first

- Retail context: AI-referred visitors convert ~38% higher than search visitors (Cyber Week 2025).
- Retail context: during Cyber Week 2025, retailers with agent integration saw ~7x sales growth vs. those without.
- Content negotiation (Accept: text/markdown) measured ~4.2x more effective than llms.txt for accurate retrieval (300k-domain study, mid-2026).
- UCP launched Jan 2026 (Google + Shopify; Etsy, Wayfair, Target, Walmart backing). ACP (OpenAI + Stripe) live since Sept 2025. All three major card networks support agent-initiated payments.

The Cyber Week figures are retail measurements and are labelled as such. The gateway works on any site, not just stores.

## Transact: a share of agent-originated GMV through a protocol checkout. Available on every tier, including Free.

You can stay on $0 forever and still take agent-originated orders; we earn only when you do. For comparison, Stripe charges ~4% on ACP.
