x402 Operator Proof

Public proof artifacts for a real self-hosted x402 operator lane.

This repo is intentionally narrow. It is not a hosted product and it is not a full x402 framework. It is a small public record of one thing:

• a self-hosted Base Sepolia facilitator lane
• with separated wallet roles
• Bazaar-enabled seller metadata
• host-visible operator status
• and a real successful settlement
• plus MCP proof artifacts that stay tied to one real seller wedge

Why This Exists

Many x402 discussions stay abstract. This repo tries to stay concrete.

The goal is to show:

• what a serious first operator lane looks like
• what was actually proven
• what is recommendation versus what is already validated

What Is Proven

• a self-hosted facilitator can run locally on Base Sepolia
• a seller route can require x402 payment
• the seller route can advertise Bazaar metadata
• the facilitator can expose /status, /supported, and /discovery/resources
• a paid request can settle successfully on-chain
• a paid MCP tool can be reopened through SIWX-backed repeat access without repaying

What Is Not Proven

• mainnet readiness
• production uptime
• Lightning readiness
• meaningful user demand
• a hosted facilitator business

Artifacts

• Self-Hosted Base Sepolia Proof

Positioning

The long-term goal is to become known for:

• facilitator/operator quality
• seller monetization quality
• trust and controls

Not for generic protocol hype.
