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())

Example Response

{
  "kraken_btc": 67480.00,
  "coinbase_btc": 67492.00,
  "spread_usd": 12.00,
  "spread_bps": 1.78
}

Cross-Exchange Arbitrage Scanner

Scans live public spot tickers across Coinbase, Kraken, Bitstamp, Gemini, and OKX (no API key required) to detect cross-exchange crypto arbitrage opportunities, price discrepancies, and crossed markets for BTC, ETH, SOL, and other listed tokens. Use this when the user asks about crypto arbitrage, cross exchange arbitrage, cex arbitrage scanner, price spread between exchanges, buy low sell high across crypto exchanges, spot arbitrage bot, exchange price discrepancy, best bid ask across venues, or wants to check if an arbitrage opportunity currently exists between major spot exchanges. Reports spread in basis points and which venue to buy/sell on, but does not account for withdrawal time, network fees, or trading fees, so results are gross spreads only.
