IRL v0.0.1 — Deployment Protocol for Web4 Pages

Abstract. IRL (Intelligence Resource Locator) is the URL for AI. It turns a website into a Web4-compatible entity with a permanent slug, four machine-readable VCAP surfaces, and a resolver so hosting can change without breaking AI citations.

One sentence. Web4 Page is the webpage for AI. IRL is the URL for AI.

1. Resolver

The root resolver lives at the web4page.org domain root:

GET https://web4page.org/resolve/{slug}

Returns JSON: slug, host, trust, vcap (visibility, citability, performability, actionability URLs).

2. VCAP surfaces

• Visibility — web4page.json / entity profile
• Citability — llms.txt grounding file
• Performability — openapi.json for AI actions
• Actionability — mcp.json for agent tools

3. Registration

POST https://api.web4page.org/v1/resolve/register
X-API-Key: (publisher key)
{ "slug", "host", "trust", "vcap" }

4. LLM crawl contract

LLM crawlers read robots.txt and llms.txt at the domain root in one pass. llms.txt declares the resolver pattern /resolve/{slug}. No deep link traversal required.
