“Real telemetry delivered, and rare cross-stack debugging follow-through”

On 2026-07-23 I called GET /telemetry on api-algo.stelardigital.com and paid $0.005 over x402 on Algorand. The payment settled in transaction DX6P544H...UTGA and the endpoint returned a real telemetry payload.

Getting there surfaced genuine early-ecosystem interop bugs on both sides, in header names and facilitator payload shapes. This team diagnosed and fixed their half within days and adopted the compatibility findings we reported back. They also run their own buying agents against other sellers. Exactly the kind of counterparty agent commerce needs.
