JavaScript — @x402/fetch

Offizieller x402-v2-Client. Installieren Sie @x402/fetch und @x402/evm. Der ältere Paketname x402-fetch ist die veraltete v1-Linie und sollte für diese Endpunkte nicht verwendet werden.

import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

// Official x402 v2 client. The older package name "x402-fetch" is the deprecated v1 line.
const account = privateKeyToAccount(process.env.EVM_PRIVATE_KEY);
const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(account) }],
});

const res = await fetchWithPayment(
  "https://forge-tools.dentreprise.workers.dev/api/supplier-due-diligence?name=Nokia+Oyj&country=FI&vat=FI01120389"
);
console.log(await res.json());

Python — x402

Offizielles PyPI-Paket x402. Nutzen Sie x402HttpxClient (async) oder x402_requests (sync) nach register_exact_evm_client mit EthAccountSigner.

import asyncio
import os
from eth_account import Account
from x402 import x402Client
from x402.http.clients import x402HttpxClient
from x402.mechanisms.evm import EthAccountSigner
from x402.mechanisms.evm.exact.register import register_exact_evm_client

# Official PyPI package: x402
account = Account.from_key(os.environ["EVM_PRIVATE_KEY"])
client = x402Client()
register_exact_evm_client(client, EthAccountSigner(account))

async def main():
    async with x402HttpxClient(client) as http:
        res = await http.get("https://forge-tools.dentreprise.workers.dev/api/supplier-due-diligence?name=Nokia+Oyj&country=FI&vat=FI01120389")
        print(res.json())

asyncio.run(main())

# Sync alternative:
# from x402 import x402ClientSync
# from x402.http.clients import x402_requests
# client = x402ClientSync()
# register_exact_evm_client(client, EthAccountSigner(account))
# with x402_requests(client) as session:
#     print(session.get("https://forge-tools.dentreprise.workers.dev/api/supplier-due-diligence?name=Nokia+Oyj&country=FI&vat=FI01120389").json())

MCP-Server — forge-agent-mcp

stdio deckt den gesamten Katalog (beide API-Hosts) ab. Klonen Sie forge-agent-mcp und zeigen Sie mit Ihrem MCP-Client auf src/server.mjs. Die gehostete Streamable-HTTP-Remote am ursprünglichen Gateway stellt weiterhin nur die ursprünglichen Gateway-Tools bereit.

{
  "mcpServers": {
    "forge-agent-hub": {
      "command": "node",
      "args": ["/path/to/forge-agent-mcp/src/server.mjs"]
    },
    "forge-agent-api": {
      "url": "https://x402-gateway.forge-x402.workers.dev/mcp",
      "transport": "streamable-http"
    }
  }
}

LangChain-Tool-Wrapper

Kapseln Sie dieselben x402-Clients als LangChain-Tool mit DynamicStructuredTool (@langchain/core) oder @tool (langchain_core).

import { DynamicStructuredTool } from "@langchain/core/tools";
import { z } from "zod";
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

const account = privateKeyToAccount(process.env.EVM_PRIVATE_KEY);
const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(account) }],
});

export const supplier_due_diligence = new DynamicStructuredTool({
  name: "supplier_due_diligence",
  description: "Supplier due diligence for any company name (optionally VAT number and country): VIES VAT check, UK Companies House profile when country=GB, GLEIF LEI candidates with entity and registration status, and sanctions screening (OFAC, EU, FR, UK), with a pass/review/fail verdict and flags.",
  schema: z.object({}),
  func: async (input) => {
    const res = await fetchWithPayment("https://forge-tools.dentreprise.workers.dev/api/supplier-due-diligence" + "?" + new URLSearchParams(input));
    return JSON.stringify(await res.json());
  },
});

import os

from eth_account import Account
from x402 import x402ClientSync
from x402.http.clients import x402_requests

account = Account.from_key(os.environ["EVM_PRIVATE_KEY"])
client = x402ClientSync()
register_exact_evm_client(client, EthAccountSigner(account))
