Facilitator

Endpoint: https://facilitator.mcpay.tech

A high-availability passthrough proxy for x402 facilitators. It provides a single stable entrypoint with failover, retries, and load balancing across multiple upstream facilitators.

✨ Features

• Passthrough Proxy: Transparently forwards requests to upstream x402 facilitators.
• On-Demand Health Checks: Lightweight, stateless monitoring of facilitator health.
• Automatic Failover: Routes around failures by switching to healthy facilitators.
• Retry Logic: Exponential backoff for transient network or service errors.
• Load Balancing: Distributes traffic randomly among available healthy targets.
• Monitoring Endpoints: Health (/health) and status (/status) endpoints for observability.
• Edge & Serverless Ready: Stateless by design, no background processes required.

🔗 Upstream Targets

The proxy currently balances across:

• https://facilitator.x402.rs
• https://facilitator.payai.network

Additional facilitators (Coinbase, thirdweb, bankr, meridian, ABK LABS, mogami) can be added as they publish stable endpoints.

Your requests will automatically be routed through healthy upstream facilitators.

📊 Monitoring

• GET /health → quick health check (200 if proxy is up)
• GET /status → JSON report of upstream health and routing state
