Search Console for agentic commerce.

The proof

What an agent receives: before vs. after

The same product URL, the same request — one capture without the gateway, one with it.

Before — raw PDP HTML

~22,789 tokens

91,226 bytes

After — gateway markdown

~328 tokens

1,315 bytes

98.6% smaller

Roughly 69× less context for the same buying facts — and the facts get better, not worse: front-loaded price, stock, shipping, and returns.

Before — the raw PDP HTML

Theme CSS, mega-menu, product JSON blobs, tracking snippets, a reviews widget, upsells, modals, a cookie banner, a newsletter modal, and cart JS.

The machine-readable price first appears at character offset 23,185, buried in a JSON blob. Availability is an unlabeled span; shipping and returns sit inside collapsed accordions after 18 reviews of widget markup.

After — gateway markdown

Price on line 4, availability on line 5; shipping, returns, and per-variant availability in the first screenful. An excerpt of the actual response:

GET /products/alpine-trail-pack-28l · Accept: text/markdown
# [Alpine Trail Pack 28L](https://basecamp-supply.example/products/alpine-trail-pack-28l)

- **Brand:** Basecamp Supply Co
- **Price:** $148.00
- **Availability:** In stock
- **Shipping:** Free US shipping on orders over $75; standard shipping $6.95.
  - Free shipping threshold: $75.00
  - Ships to: US, CA
  - Delivery estimate: 3-6 days
- **Returns:** 60-day returns. Items must be unused with tags attached.
  - Return window: 60 days
  - Policy: https://basecamp-supply.example/policies/returns

Same URL, same substance, different format. Browsers get your HTML unchanged, and Googlebot always receives the canonical HTML. Deterministic capture from a Shopify-style PDP fixture for a fictional demo store (Basecamp Supply Co), regenerated and conformance-checked by pnpm demo:capture — measurements, not estimates.

How it works

One middleware install, three outcomes

01 /

Install the gateway middleware

npm install @rebilder/gateway, wire it to your source of truth (products, policies, catalog), and drop the proxy in front of your routes. No theme rewrite, no new stack.

02 /

Agents get clean markdown, humans get your site untouched

Every request is classified. Agents asking for markdown get a clean transformation of the canonical page, rendered from your source of truth. Humans and search crawlers pass through unchanged — Googlebot always gets your canonical HTML.

03 /

Watch the funnel in Console

Every gateway request is a recorded event: which agent visited, which URL, what it was served. The Console shows who came, what they saw, and where to fix coverage.

The whole Next.js integration — a Response short-circuits with markdown, null continues to your HTML pipeline unchanged:

proxy.ts
// proxy.ts (Next 16) — middleware.ts on Next ≤15 is identical
import { NextResponse } from 'next/server'
import { createGatewayProxy } from '@rebilder/gateway/next'
import { gatewayConfig } from './lib/gateway-config'

const gateway = createGatewayProxy(gatewayConfig)

export default async function proxy(req: Request) {
  return (await gateway(req)) ?? NextResponse.next()
}

export const config = { matcher: ['/products/:path*', '/policies/:path*', '/collections/:path*'] }

The observation layer

Every gateway request is a recorded event

Which agent visited, which URL, what it was served — the gateway records it all. The Console turns that stream into a funnel you can act on: see which agents already reach your store, where you get cited, and where coverage needs fixing.

  1. Visits

    An agent fetches your pages through the gateway.

  2. Cited

    Your store shows up in the assistant’s answer.

  3. Referred

    The shopper arrives on your site via agent handoff.

  4. Conversions

    The order is attributed to agent traffic.

Trust

Your data never feeds a negotiation engine

Per-merchant data is never sold, shared, or used to negotiate against you. Only aggregated, anonymized benchmarks ever cross the wall — written into the terms from day one and enforced architecturally: separate schemas and credentials, an explicit allowlist of aggregate metrics, and an audit log on every cross-boundary query.
