Gratis demo / voorbeeld

Deze tool staat op de wave-1-worker. ?demo=1 geeft een gelabeld voorbeeld of fragment terug met HTTP 200 en zonder betaling. De body is geen livedata. De eerste 3 geslaagde echte aanroepen per IP per UTC-dag zijn ook gratis.

JavaScript — @x402/fetch

Officiële x402-v2-client. Installeer @x402/fetch en @x402/evm. De oudere pakketnaam x402-fetch is de verouderde v1-lijn en moet niet voor deze endpoints worden gebruikt.

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/fr-communes?name=Annecy"
);
console.log(await res.json());

Python — x402

Officieel PyPI-pakket x402. Gebruik x402HttpxClient (async) of x402_requests (sync) na register_exact_evm_client met 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/fr-communes?name=Annecy")
        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/fr-communes?name=Annecy").json())

MCP-server — forge-agent-mcp

stdio dekt de volledige catalogus (beide API-hosts). Clone forge-agent-mcp en wijs je MCP-client naar src/server.mjs. De gehoste Streamable-HTTP-remote op de oorspronkelijke gateway biedt nog steeds alleen de oorspronkelijke gateway-tools.

{
  "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-toolwrapper

Pak dezelfde x402-clients in als LangChain-tool met DynamicStructuredTool (@langchain/core) of @tool (langchain_core).
