AI-readable discovery

Public information

Read the structured business information and inspect the published discovery documents.

Machine-readable documents do not by themselves establish a live AI agent, checkout or business ownership.

Public Directory policy

One canonical business record, many useful public signals.

This page presents the current public Directory profile. Registry verification, business ownership, crawler evidence and agent capabilities remain separate signals rather than being collapsed into one vague “verified” badge.

Canonical record One public listing identity for this business.
Registry evidence Business verification is shown independently from owner claims.
AI-readable data Public discovery documents are separate from live AI interactions.
