x402 Service Discovery MCP Server

⭐ Star to help others find this — if x402Scout has saved you time, a star helps other developers find it

The community-built Bazaar for the x402 agentic economy — a continuously growing catalog of live services with real-time quality signals, facilitator-compatibility checks, and ERC-8004 trust scoring. The discovery layer that Coinbase's own PROJECT-IDEAS.md asked the community to build.

ScoutGate — Instant x402 API Monetization

Wrap any existing API in x402 payments in under 2 minutes — no protocol knowledge required

The x402 ecosystem's biggest friction point has been supply-side: getting an API behind x402 payments requires understanding EIP-712 headers, facilitator registration, and settlement logic. ScoutGate removes all of it.

# Register your existing API (30 seconds)
curl -X POST https://x402-scoutgate.onrender.com/register \  -H "Content-Type: application/json" \  -d '{"api_url": "https://your-api.com", "wallet_address": "0xYourWallet", "price_usd": 0.01, "name": "My API"}'
# Returns: {"proxy_url": "https://x402-scoutgate.onrender.com/api/abc123", "api_id": "abc123"}

That's it. Your API is now x402-enabled, auto-listed in x402Scout, and settling on Base mainnet in real USDC. ScoutGate handles facilitator integration, EIP-712 verification, and settlement.

Fee model: 2% per transaction (min $0.002). Live at: https://x402-scoutgate.onrender.com | Register your API

scout_relay — Autonomous Payment Router

Route, execute, and audit x402 payments in a single call

Where the Discovery MCP finds what to call, scout_relay handles calling it — discovering the best service, making the x402 payment, retrying on failure, and returning the result. One call. Fully autonomous.

# Route an intent to the best matching x402 service
curl -X POST https://x402-scout-relay.onrender.com/route \
  -H "Content-Type: application/json" \
  -H "X-Payment: <your-x402-payment-header>" \
  -d '{"intent": "blockchain analytics for wallet 0xABC", "max_budget_usd": 0.05}'
