What It Does

Identifies optimal execution windows based on volatility and liquidity. Computed by APEX Runner from live market data, not from backtests.

How to Use

The agent makes an x402-authenticated GET request to:

https://apexrunner.ai/signals/execution-window-optimizer

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/execution-window-optimizer")
print(response.json())
