verify_trade → Sentinel first; verify_claim → RV /v1/check only. Not Sentinel-only.

Do not share (legacy / wrong routing)

agent_cb1a9997 — Mis-registered as “Sentinel” but points at RV (api.thoughtproof.ai/v1/check). Do not share as Sentinel.

Purpose

x402 / API revenue receiving (Base USDC)

x402
