JavaScript — @x402/fetch

Cliente oficial x402 v2. Instale @x402/fetch e @x402/evm. O nome de pacote antigo x402-fetch é a linha v1 descontinuada e não deve ser usado nestes endpoints.

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/uuid-v7?count=3"
);
console.log(await res.json());

Python — x402

Pacote oficial PyPI x402. Use x402HttpxClient (async) ou x402_requests (sync) depois de register_exact_evm_client com 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/uuid-v7?count=3")
        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/uuid-v7?count=3").json())

Servidor MCP — forge-agent-mcp

O modo stdio cobre o catálogo completo (ambos os anfitriões de API). Clone forge-agent-mcp e aponte o seu cliente MCP para src/server.mjs. O remoto Streamable HTTP alojado no gateway original continua a expor apenas as ferramentas desse gateway.

{
  "mcpServers": {
    "forge-agent-hub": {
      "command": "node",
      "args": ["/path/to/forge-agent-mcp/src/server.mjs"]
    },
    "forge-agent-api": {

Wrapper de ferramenta LangChain

Envolva os mesmos clientes x402 como ferramenta LangChain com DynamicStructuredTool (@langchain/core) ou @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 uuid_v7 = new DynamicStructuredTool({
  name: "uuid_v7",
  description: "RFC 9562 UUIDv7 generator (time-sortable, 1-100 per call, optional timestamp) and UUID validator/decoder (version, variant, embedded timestamp for v1/v7).",
  schema: z.object({}),
  func: async (input) => {
    const res = await fetchWithPayment("https://forge-tools.dentreprise.workers.dev/api/uuid-v7" + "?" + new URLSearchParams(input));
    return JSON.stringify(await res.json());
  },
});

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

@tool
def uuid_v7() -> str:
    """RFC 9562 UUIDv7 generator (time-sortable, 1-100 per call, optional timestamp) and UUID validator/decoder (version, variant, embedded timestamp for v1/v7)."""
