cross-exchange-spread
What It Does
Live spread between Kraken, Coinbase, and Hyperliquid for arb detection. This signal is computed in real time from APEX Runner's live autonomous trading system operating across Kraken, Coinbase Advanced Trade, and Hyperliquid — not from backtests or third-party aggregators.
When to Use
- Before routing orders between exchanges
- To detect arb windows
- As input to optimal-order-routing
How to Use
The agent makes an x402-authenticated GET request to:
https://apexrunner.ai/signals/cross-exchange-spread
The x402 client handles payment authorisation automatically. No API key, no account, no subscription required — just an EVM wallet with USDC on Base mainnet.
# Example using the x402-python client
from x402.client import x402_get
response = x402_get(
url="https://apexrunner.ai/signals/cross-exchange-spread",
private_key=os.environ["EVM_PRIVATE_KEY"]
)
print(response.json())

"kraken_btc": 67480.00,
