https://apexrunner.ai/signals/fear-greed

The x402 client handles payment automatically. No API key, no account, no subscription — just an EVM wallet with USDC on Base mainnet (no ETH needed).

python

# pip install "x402[evm,requests]"
import os

import requests
from eth_account import Account
from x402 import max_amount, x402ClientSync
from x402.http.clients import wrapRequestsWithPayment
from x402.mechanisms.evm.exact import register_exact_evm_client
from x402.mechanisms.evm.signers import EthAccountSigner

client = x402ClientSync()
register_exact_evm_client(client, EthAccountSigner(Account.from_key(os.environ["EVM_PRIVATE_KEY"])))
client.register_policy(max_amount(10000))  # never sign more than the list price ($0.01 USDC)

session = wrapRequestsWithPayment(requests.Session(), client)
response = session.get("https://apexrunner.ai/signals/fear-greed")
print(response.json())
