## Crawl and access policy

Edge-cached serving. Cached discovery pages serve normally (HTTP 200) to bots
and humans. Prefer MCP/API for programmatic access at scale.

- REST API:    https://entia.systems/developers
- MCP Server:  https://mcp.entia.systems/mcp
- Pricing:     https://entia.systems/.well-known/ai-pricing.json
- Manifest:    https://entia.systems/.well-known/mcp.json
- Contact:     partnerships@entia.systems

Crawler-facing headers when structured access is preferred:
  X-API-Access:           https://entia.systems/developers
  X-MCP-Access:           https://mcp.entia.systems/mcp
  X-Commercial-Contact:   partnerships@entia.systems

- [Socio CP — Spanish postal-code profiles](https://entia.systems/v1/socio/es/cp/28001): socioeconomic metrics per CP. Formats: HTML, JSON-LD (`.jsonld`), JSON (`.json`).
- [Sector pages](https://entia.systems/sectores/dental): sector landings with Service + FAQPage + CNAE + areaServed.
- [Products](https://entia.systems/products/entia-home): product schemas with FAQPage + BreadcrumbList + Offers.

- [International homes index](https://entia.systems/sitemaps/sitemap-countries.xml)

- [Static sitemap](https://entia.systems/sitemaps/sitemap-static.xml)
- [Blog sitemap](https://entia.systems/blog/sitemap-blog.xml)

## Content types

- `text/html` (default)
- `application/ld+json` (Schema.org JSON-LD; often `.jsonld`)
- `application/json` (flat data; often `.json`)

Content negotiation via Accept or extension on `/v1/socio/es/*` and most
`/v1/identity/**` entity pages.

## JSONL bulk feeds (machine-readable discovery samples)

- [Feed index](https://entia.systems/llm/index.json)
- Sector samples under https://entia.systems/llm/es/{sector}.jsonl
  (dental, legal, estetica, talleres, inmobiliarias, reformas, psicologia,
  restaurantes, veterinarios, gimnasios, asesorias, …)

Bulk sample feeds remain discovery-oriented; they do not grant training rights.
Scale access → MCP / licence.

## Crawler policy

- Legitimate search and LLM indexers welcome for discovery (Googlebot, Bingbot,
  GPTBot, ClaudeBot, PerplexityBot, ChatGPT-User, OAI-SearchBot, Google-Extended,
  anthropic-ai, and peers).
- Respect robots.txt. Crawl-delay: 2 for the default UA.
- ai-train=no does not mean block crawl; it means training is not licensed.
- Aggressive scanners may see 429/503 for rate control.

## Attribution when citing discovery content

- Attribute: "Source: ENTIA Systems (entia.systems)"
- Prefer the canonical entity or article URL.
- Territorial profiles expose per-field valueReference (AEAT, INE, SEPE, Catastro, MITECO, CNMC).
