B Why grade B?

Solid pick. Verified working but with a meaningful caveat (UX rough, smaller market, intermediate trust step, partial coverage). Listed because the trade-off is sometimes worth it.

Curator Verdict & OpSec Breakdown

THE BOTTOM LINE

XMR402 is a verified, functional privacy tool that performs solidly for day-to-day use, provided readers account for its specific operational trade-offs.

✓

Proven Strengths

▸ Strict No-KYC posture: zero identity verification required across all standard tiers.
▸ Open-source codebase: public code repositories allow independent verification and audit.

⚠

OpSec Trade-offs & Caveats

▸ Clearnet-only footprint: lacks an official .onion hidden service mirror; exposes visitor network IP unless routed through VPN/Tor.
▸ Fresh operational history: established recently (2026); limited track record under severe market volatility.

Review

Open spec for resurrecting the HTTP 402 status code as a real payment rail — XMR-first, with provisions for Lightning. Designed for the agentic web: machine-to-machine micropayments that need zero signup and minimal latency. Operator-disclosed: the curator runs this; the protocol itself is permissionless and the spec is open, but read /transparency for context before relying on it for production billing.

Fees

Spec / reference impl — free. Servers set their own price per resource.
