# Agent Authentication Policy — Half Price Print

## Overview
Half Price Print (https://www.halfpriceprint.ae) supports public catalog browsing, product search, and instant pricing calculations without API keys or authentication credentials.

## Authentication & Authorization
- **Public Endpoints**: Browsing catalog items, sitemaps, and LLM text files requires no credentials.
- **Agent Registration**: Automated crawlers and AI assistants must identify via a standard `User-Agent` string.
- **Checkout Policy**: Payments require explicit human approval. Autonomous agents transacting on a buyer's behalf must use Shopify Shop Skill (`https://shop.app/SKILL.md`) or UCP endpoints (`https://www.halfpriceprint.ae/api/ucp/mcp`).
