Funding Rate Monitor - Ironflow

Funding is the carry cost of a perp position. Monitoring it across markets surfaces crowded trades and basis opportunities.

Current rates across every market

import asyncio
from ironflow_sdk import Ironflow

THRESHOLD = 0.0005  # 0.05% per interval

async def scan():
    async with Ironflow("if_your_api_key") as client:
        markets = await client.markets(market_class="perp")
        for m in markets:
            page = await client.funding(m.display_symbol, limit=1)
            if not page.data:
                continue
            rate = float(page.data[0].rate)
            if abs(rate) > THRESHOLD:
                print(f"{m.display_symbol:24s} {rate:+.5f}")

asyncio.run(scan())

This sweeps native and HIP-3 builder perps in one pass — builder markets frequently carry the largest divergences.
