# schema.nsgoods.org

This host serves developers, SEO practitioners, and AI pipeline builders who need to evaluate whether a given public web page is optimally structured for generative AI and answer-engine extraction (GEO). It focuses narrowly on structural and metadata quality signals — not live search rankings or compliance — and returns machine-readable results with a cryptographic proof of delivery.

## When to use this host

Use this host when an agent needs to audit a single public web page for AI/answer-engine extractability, obtain a signed proof of that audit, and receive actionable remediation steps. Do not use it for real-time SEO ranking data, keyword research, backlink analysis, or compliance audits — dedicated SEO platforms or legal tools are more appropriate for those needs. It is also not suitable for pages behind authentication or paywalls, as it only analyzes publicly accessible URLs.

## Capabilities

### Page Extractability Analysis

Analyzes a public URL and returns a signed extractability score with per-category breakdowns (structured data, metadata, machine readability, etc.) and a prioritized fix list to improve AI/answer-engine discoverability.

- **`fetch-extractability-score`** — Returns a signed extractability score, per-category breakdown, and actionable fixes for a given URL, indicating how well a page is structured for AI/answer-engine extraction.
