What does a funding rate arbitrage scanner do?

Scans perp funding rates across exchanges, flags mispricings (e.g., pay 0.01% on one, receive 0.02% on another) for hedged arb.

Why is OKX API so slow for funding rates?

No bulk endpoint—one call per symbol, rate-limited. Parallelize with 8 workers to hit ~8s for 285 symbols.

Will there be a unified crypto exchange API library?

Likely—history says yes. Watch for PyPI gems post-2025 as DeFi demands standardize.
