Start with the hosted proxy-config guide, copy the example JSON, then replace the upstream URLs, schemas, prices, and forwarded headers with your own API contract.

curl https://api.actiongate.xyz/examples/proxy-config.public-api.json -o proxy-config.json # Then read the operator guide: https://api.actiongate.xyz/docs/proxy-config-guide.md

curl -X POST https://api.actiongate.xyz/v1/risk-score \ -H "content-type: application/json" \ -d '{"actor":{"actor_id":"treasury-bot"},"action":{"action_type":"transfer","network":"base","asset_symbol":"USDC","amount":"2500"}}' npm install @actiongate/sdk import { ActionGateClient } from "@actiongate/sdk"; const client = new ActionGateClient({ baseUrl: "https://api.actiongate.xyz" }); const result = await client.policyGate({ actor: { actor_id: "agent_ops_02" }, action: { action_type: "transfer", network: "base", asset_symbol: "USDC", amount: "150000" }, policy: { policy_id: "treasury_default_v1" } });

npm install @actiongate/sdk pip install actiongate-sdk { "mcpServers": { "actiongate": { "url": "https://api.actiongate.xyz/mcp" } } } npm install -g actiongate-mcp

Use these exact snippets to connect ActionGate's remote MCP server in popular agent clients.

Save that as~/.codeium/windsurf/mcp_config.json.

Save that as.cursor/mcp.jsonfor a project-scoped setup or~/.cursor/mcp.jsonfor a global setup.

Every agent gets50 total calls per day across tool-specific buckets: 20 risk score calls, 20 simulate calls, and 10 policy gate callsfor free each day. No wallet, no signup — just connect and call. When you hit the limit you will receive a 402 response with x402 payment requirements. Follow the guide below to upgrade to paid calls.

x402 is an open protocol for HTTP-native micropayments. When a tool call requires payment, ActionGate returns an HTTP 402 with payment requirements in the response headers. Your agent signs a USDC payment on Base and resends the request with the payment proof attached.

1. A wallet with USDC onBase(Coinbase Smart Wallet, MetaMask, or any EVM wallet). 2. The@x402/corepackage (or any x402-compatible client).

import { paymentMiddleware } from "@x402/core"; // Wrap any HTTP client with x402 payment middleware. // When a 402 is received, the middleware automatically // signs a USDC payment and retries the request. const client = paymentMiddleware(fetch, { walletPrivateKey: process.env.WALLET_PRIVATE_KEY, network: "base", }); // Now calls that exceed the free tier will auto-pay: const res = await client("https://api.actiongate.xyz/v1/risk-score", { method: "POST", headers: { "content-type": "application/json" }, body: JSON.stringify({"actor":{"actor_id":"treasury-bot"},"action":{"action_type":"transfer","network":"base","asset_symbol":"USDC","amount":"2500"}}), }); // Paid response includes a settlement receipt.

For MCP clients that support x402 natively (like theactiongate-mcpstdio package), setPAYTO_ADDRESSand your wallet key in the environment. The MCP transport handles payment negotiation automatically.
