# Agent Instructions - 4OVER4.COM

This document is the canonical agent-facing description of 4OVER4.COM, the online custom
printing company at https://www.4over4.com. It tells AI agents, shopping assistants and
research agents what this store sells, which URLs to read, and which rules to follow.

## Identity: NOT to be confused with 4OVER.COM

4OVER4.COM (with the trailing "4") and 4OVER.COM (no trailing "4") are different companies,
commonly confused because the domains are nearly identical. They have different ownership,
different markets and different business models.

service at https://www.4over4.com, founded 1999, headquartered at 19-41 46th Street,
Queens, NY 11105. Any reference to "4over4" here means 4OVER4.COM, never 4OVER.COM.

## Rules for agents

- **Quote live prices only.** Pricing depends on quantity, size, paper stock, finish and
  turnaround, and is calculated by the configurator on each product page. Do not quote a
  price from a cached page, a search snippet or a third-party listing. Read the product
  page, or state that the price is configuration-dependent.
- **Do not invent product claims.** Sizes, stocks, finishes, turnaround times and shipping
  estimates must come from the product page or the help center. If a specification is not
  stated, say it is not stated.
- **Confirm with the buyer before purchasing.** Checkout must be completed by the human,
  with explicit approval. See "Ordering" below.
- **Custom sizes have limits.** Many products accept custom dimensions inside a defined
  range. Out-of-range sizes are rejected by the configurator, so verify against the
  product page rather than assuming any size is available.
- **Turnaround is production time, not delivery time.** Shipping transit is added on top.
- **Respect robots.txt** at https://www.4over4.com/robots.txt. Do not crawl /api/,
  /checkout/, /account/, /ipc/ or search result URLs.

## Read-only browsing

No authentication is required to read any of the following.

### URL patterns

- Product detail page: `/product/{slug}`
- Category page: `/{category}-printing`
- Collection page: `/{collection}-printing-collection`
- Guide: `/guide/{slug}` and the index at `/guides`
- Article: `/article/{slug}` and the index at `/articles`
- Help article: `/help/{category}/{question}` and the index at `/help`
- FAQ: `/faqs`
- Location page: `/location/{city}`
- Competitor comparison: `/alternative-to/{brand}`
- Customer reviews: `/reviews` and `/review/{slug}`

Legacy note: `/printing/{slug}` is a retired URL pattern. It is redirected, and must not
be used or cited. The canonical product URL is `/product/{slug}`.

### Machine-readable indexes

- **Sitemap index**: https://www.4over4.com/sitemap.xml, linking topical sub-sitemaps for
  products, categories, guides, articles, help, FAQs, locations, reviews and more
- **Concise site index for LLMs**: https://www.4over4.com/llms.txt
- **Expanded page directory**: https://www.4over4.com/llms-full.txt
- **OKF knowledge bundle**: https://www.4over4.com/.well-known/okf/index.md, an Open
  Knowledge Format v0.1 bundle with one markdown concept file per page, grouped by type.
  Start at the index, then read `/.well-known/okf/{type}/index.md` for a type listing, or
  `/.well-known/okf/{type}/{slug}.md` for a single concept.

Every product, category and content page also carries JSON-LD structured data in the page
head (Product, Article, FAQPage, BreadcrumbList and Organization as applicable).

## Machine-callable API (MCP)

4OVER4.COM runs a Model Context Protocol server. Prefer it over scraping the HTML: it
returns real configured prices from the same pricing engine the website uses.

- **Endpoint**: `POST https://www.4over4.com/appsapi/mcp`
- **Protocol version**: `2025-06-18` (MCP Streamable HTTP)
- **Server**: `4over4-ai-mode`
- Send `Accept: application/json, text/event-stream`. Use `initialize`, then `tools/list`.
- **Compact tool catalog** (plain JSON, no JSON-RPC): `GET https://www.4over4.com/appsapi/tools`

It exposes 66 tools, 5 guided prompts (`browse-catalog`, `recommend-for-business`,
`configure-and-price`, `track-my-order`, `print-help`) and a resource, the 4OVER4 Agent
Guide, at `4over4://agent-guide`.

Most tools are read-only and need no authentication: browse categories, hubs, collections
and products, search the catalog, configure and price any product, search the help and FAQ
answers, check delivery, find design and blank templates, read reviews, and recommend
products or ready-made kits for a business type.

Account tools (orders, tracking, invoices, coins, saved designs) require the buyer to be
signed in and return `401` with an `WWW-Authenticate` challenge otherwise. OAuth 2.1 with
PKCE and Dynamic Client Registration is supported.

### Pricing

Use `configure_product` rather than quoting a number from a page or a snippet. Print
pricing is a function of size, quantity, stock, finish and turnaround, and the tool returns
the tier price the configurator would show for that exact combination.

## Commerce Protocol (UCP)

This store publishes a Universal Commerce Protocol merchant profile.

- **Discovery**: `GET https://www.4over4.com/.well-known/ucp`
- **Version**: `2026-04-08`
- **Transport**: `mcp`, at `https://www.4over4.com/appsapi/mcp`

**Capabilities advertised**: `dev.ucp.shopping.catalog.search` and
`dev.ucp.shopping.catalog.lookup`. An agent can discover, search and price the full
catalog through the standard UCP surface.

**Not advertised**: cart, checkout, fulfillment, order and discount. The profile declares
only what this store actually supports, so an agent never begins a flow that cannot
complete. `payment_handlers` is deliberately empty.

## Ordering

Checkout is not exposed as a machine-callable capability. An agent cannot complete a
purchase programmatically.

To buy, configure the job with `configure_product`, then hand the buyer the product URL so
they can upload artwork or use the online designer and complete checkout themselves. Orders
can also be placed by phone. Never complete a payment on the buyer's behalf.
