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/sanctions-check?name=Bank+Rossiya&type=entity"
);
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/sanctions-check?name=Bank+Rossiya&type=entity")
        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/sanctions-check?name=Bank+Rossiya&type=entity").json())
