Try It Yourself

Any agent. Any language. One command.

curl
curl -H "Accept: application/json" \
  shadow.geostack.xyz/geostack/

# Returns clean JSON with state proof and actions
Python
import requests

r = requests.get(
  "https://shadow.geostack.xyz/geostack/",
  headers={"Accept": "application/json"}
)

product = r.json()
# product["actions"]["join_waitlist"]
# → "POST /api/waitlist"
HTML (browser)
# Same URL in a browser:
GET shadow.geostack.xyz/geostack/
Accept: text/html

# Returns semantic HTML with forms
# - agents can POST directly

Content Negotiation - the dual-interface core

One URL. Two formats. The Accept header decides. Send Accept: application/json and you get structured data. Send Accept: text/html and you get a clean, semantic storefront with POST-able forms. Both are always in sync. This is the dual-interface architecture - the dual-interface architecture.

For Merchants

What your store's shadow looks like.

Every product gets a verifiable, agent-readable page. Here's a real example of what an agent sees when it browses a shadow storefront.
