Discover and call pay-per-request (x402) APIs, ranked by reliability, latency and price.
MCP Server for AI agents to discover and call pay-per-request APIs via EntRoute.
Give Claude, Cursor, Windsurf, or any MCP-compatible agent access to 350+ verified x402 API endpoints across 110+ capabilities -- DeFi prices, web search, prediction markets, news, and more.
claude mcp add entroute -- npx @entroute/mcp-server
Add to your claude_desktop_config.json:
{
"mcpServers": {
"entroute": {
"command": "npx",
"args": ["@entroute/mcp-server"]
}
}
}
Add to your MCP settings with command npx @entroute/mcp-server.
discover_paid_apiFind ranked, verified API endpoints for any capability. Supports natural language intent or explicit capability IDs.
"Find me an API to get the current price of ETH"
-> Returns ranked endpoints with pricing, success rates, and latency metrics
list_capabilitiesBrowse all available capability types. Filter by tag or search by keyword.
call_paid_apiExecute a discovered endpoint. Optionally handles x402 payments automatically when a wallet is configured.
To enable automatic x402 payments, set these environment variables:
EVM_PRIVATE_KEY=0x... # Wallet private key for USDC payments on Base
MAX_PAYMENT_PER_REQUEST=0.05 # Max USD per request (default: $0.05)
Without a wallet, the server still discovers endpoints -- you just can't auto-pay for 402-protected ones.
| Variable | Default | Description |
|---|---|---|
EVM_PRIVATE_KEY | -- | Hex private key for x402 payments |
MAX_PAYMENT_PER_REQUEST | 0.05 | Spending cap per request in USD |
Once installed, ask your agent:
The agent will use discover_paid_api to find endpoints, show you the options with pricing, and call the best one.
