GET /api/x402-cdp-canary

unprobed

No-body $0.001 x402 settlement test for funded agents. Verifies the buyer wallet, facilitator, USDC payment path, and paid delivery end-to-end by returning a timestamped pong only after successful settlement.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
