x402-insights — Spend Observability

Category: Infrastructure & Tooling

Repo: https://github.com/Bortlesboat/x402-insights

Instruments the six lifecycle hooks on x402Facilitator (onBeforeVerify, onAfterVerify, onVerifyFailure, onBeforeSettle, onAfterSettle, onSettleFailure) to capture spend, latency, and errors per endpoint.

What it shows:

• Cost concentration by endpoint
• Verify vs settle latency split (settle dominates ~20:1 in practice)
• Retry spend as % of total
• Error rate and failed settlement cost

Integration:

import { attachInsights } from "@x402-insights/facilitator";
attachInsights(facilitator, { baseUrl, apiKey, source: "my-facilitator" });

Tested on Base Sepolia with real verify/settle calls — not simulated traffic.

Reopened this against the canonical repo at x402-foundation#1938 because coinbase/x402 is currently a fork of x402-foundation/x402 and is behind Foundation main. Closing this fork-targeted copy to keep review in one place.
