Plumbline x402 Endpoint Check
https://plumbline.tail2a6123.ts.net:8443/v1/x402checkOverview
Verify whether an x402 payment-gated endpoint is actually usable by an agent: 402 challenge structure, payment-requirement completeness (scheme/network/amount/asset/payTo), and whether the description lets an agent construct a valid call. Inspect-only — does not spend funds, so it does not prove the endpoint can settle. Pass ?url=<endpoint>.
