ontarioprotocol.com/api/x402/refresh-listing

Refresh one existing paid Ontario x402 service listing: a fresh live readiness observation attached to its canonical profile, JSON twin and badge, after the included 30-day maintenance window. A free eligibility check runs at /api/x402/refresh-listing/validate. Payment buys a new observation, not a better grade, metadata edit, ranking, or traffic.
