Common questions

Is x402 Router safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

x402 Router: MCP server + free API to find and pay the right x402 endpoint

20,700+ LIVE x402 pay-per-call endpoints across 3,100+ services, probed every 3 hours and scored 0-100 for reliability. Agents don't need to know which x402 API is up. Ask the router.

Keywords: x402, MCP, MCP server, AI agents, agent payments, pay-per-call APIs, USDC, Base, Solana, x402 discovery, x402 router, x402 registry, HTTP 402.

Live router: https://router-production-ab89.up.railway.app (OpenAPI: /openapi.json · x402 discovery: /.well-known/x402 · health: /health)
Dashboard / registry: https://router-production-ab89.up.railway.app/dashboard
For LLMs: https://router-production-ab89.up.railway.app/dashboardllms.txt

Quick start (MCP, 30 seconds)

The server is read-only: it holds no keys and never pays. It exposes four tools: search_x402_endpoints, route_x402_request, get_registry_stats, get_paid_route_requirements.

Option A: uvx (no clone, no PyPI needed)

Claude Desktop (claude_desktop_config.json) or Cursor (~/.cursor/mcp.json):

"mcpServers": { "x402-router": { "command": "uvx", "args": ["--from", "git+https://github.com/camerxnduff/x402-router-mcp#subdirectory=mcp-server", "x402-router-mcp"] } } }

Option B: Docker

"mcpServers": { "x402-router": { "command": "docker", "args": ["run", "-i", "--rm", "ghcr.io/camerxnduff/x402-router-mcp:latest"] } } }

Or build it yourself: `docker build -t x402-router-mcp .` and use `x402-router-mcp` as the image name.

Option C: from source

git clone https://github.com/camerxnduff/x402-router-mcp

cd x402-router-mcp/mcp-server python3 -m venv .venv && . .venv/bin/activate pip install -r requirements.txt python test_client.py # calls the live router, read-only

```json

{"mcpServers":{"x402-router":{"command":"/abs/path/x402-router-mcp/mcp-server/.venv/bin/python","args":["/abs/path/x402-router-mcp/mcp-server/server.py"]}}}

Streamable HTTP: `python server.py --http 8000` serves `http://localhost:8000/mcp`.

Env overrides: X402_ROUTER_URL, X402_DASHBOARD_URL.

Try it with no install (curl)

# best live Base endpoint for a category (free preview)

curl -s -X POST https://router-production-ab89.up.railway.app/route \ -H 'content-type: application/json' -d '{"category":"Finance","chain":"Base"}'

search the registry

curl -s 'https://router-production-ab89.up.railway.app/dashboardapi/endpoints?q=weather&chain=Base&limit=5'

Why

Thousands of x402 endpoints exist, and many are dead, misconfigured or slow. The router probes every one, checks that its 402 body is valid (version, scheme, network, payTo, asset, amount), and ranks by uptime and latency, so an agent gets a working endpoint with a known price.

HTTP API

Endpoint	What
`GET /api/endpoints?q=&chain=&category=&max_price=&min_score=&sort=&limit=` (dashboard)	Search LIVE endpoints, best first
`GET /api/summary` (dashboard)	Counts by chain, category, source
`GET /api/registry` (dashboard)	Full registry (gzip)
`POST /route` (router)	Best match + top 3, free
`POST /route/paid` (router)	$0.01 USDC (x402, Base; Solana accepted): full ranked list (up to 25) with latency, reliability, price, payTo/networks and a ready-to-pay best pick
`GET /check/paid?url=` (router)	$0.002 USDC (x402): fresh live probe of one endpoint: is it up, latency, the real price and payTo it asks for now

Examples: examples/ (curl, Python, TypeScript).

MCP tools

Tool	Cost
`search_x402_endpoints`, `route_x402_request`, `get_registry_stats`, `get_paid_route_requirements`	Free
`find_best_x402_endpoint`	$0.01 USDC per call
`check_x402_endpoint`	$0.002 USDC per call

Paid tools pay inside the tool call. To enable them:

pip install "x402-router-mcp[pay] @ git+https://github.com/camerxnduff/x402-router-mcp#subdirectory=mcp-server"

export X402_EVM_PRIVATE_KEY=0x... # a dedicated, low-balance Base wallet holding a little USDC export X402_MAX_PAYMENT_USD=0.01 # per-call cap (default 0.01)

Without a key, the paid tools return the price and the x402 payment requirements instead of paying.

Payments

x402 v2: Base USDC first, Solana USDC as fallback, settled through the PayAI facilitator.
