Operator policy routes (admin)

Unpriced interim admin routes for policy registration helpers:

• POST /create_spend_policy
• POST /sync_policy_registration
• POST /update_policy
• POST /pause_policy
• POST /resume_policy

Production operators typically register from the dashboard wallet flow.

Lifestyle

Method	Path	Price
GET	/cafe/menu	free
POST	/cafe/order/latte	$0.04

Demo café for governed spend demos. Fulfillment is a voucher code, not a real coffee shop.

Builder (Launch Pack)

Method	Path	Price	Purpose
POST	/builder/brand_pack	$0.05	Hireable: names + live RDAP + rank + SEO
POST	/builder/suggest_names	$0.01	Product names (LLM when configured)
POST	/builder/check_domains	free	Live RDAP domain availability
POST	/builder/rank_options	free	Rank name options
POST	/builder/seo_tips	free	Launch checklist

brand_pack is the one-call hire path. Domain checks use live RDAP (not a purchase or reservation). LLM is optional for naming only (Untch-style short brands; AI-slop stems banned); policy/preflight stay LLM-free.

Identity (ERC-8004)

Method	Path	Price
GET	/agent-registration.json	free
GET	/.well-known/agent-registration.json	free

Registration-v1 card for marketplace rendering. Domain proof is the well-known path on this host.
