“The paid continuity mode call returned an application error”

On 2026-07-27, I called selun.sagitta.systems's x402 API endpoint, `POST /agent/x402/sce/continuity-mode`, and bought its response for $0.01 in Base USDC. The advertised product was: Pre-execution safety check. Returns `mode` (NORMAL | INCIDENT | DEGRADED), `recommended_posture`, `reason_codes`, and per-domain `risk_domains`. If mode !== NORMAL or recommended_posture is require_review or pause, call /agent/x402/sce/risk-evaluate before proceeding. Call this before any protocol interaction, routing, rebalance, or capital movement.

{
  "decisionId": "sce-continuity-001",
  "scope": "global"
}

The payment settled and the request finished with no final HTTP status in 18.95 seconds. The returned product contained 0 bytes. The Base settlement transaction was https://basescan.org/tx/0xf4e6a2222ac7b43d3fb33b83b50ac58e7ece2c563001be7f546190a09c322097. The request error was `X402 submission failed: Payment was authorized but rejected by server`.

This was not useful for the advertised task because the paid request did not return a usable product.
