# Authentication & Agent Readiness Policy (AEO / MPP / Pay-Per-Crawl)

All content on **marcaraujo.com** is architected for Agent Engine Optimization (AEO), Machine-to-Machine interoperability, and transparent crawler governance.

## 1. Agent Readiness & AEO Architecture
This website complies with standard AEO practices:
- **Structured Data:** Full JSON-LD (Schema.org) schemas for WebSite, LocalBusiness, ProfessionalService, Person, and OfferCatalog.
- **Content Negotiation:** AI agents requesting `Accept: text/markdown` automatically receive optimized Markdown versions (`llms.txt` and `llms-full.txt`).
- **Standard Discovery:** RFC 9727 API Catalog, Agent Resource Discovery (ARD), and MCP manifests.

- **Policy:** **Gratuito (Free)** with standard attribution and citation linking back to `marcaraujo.com`.

### B. Commercial Bulk Scraping & Training Crawlers (Pay-Per-Crawl)
