How this service works
Every listed perpetual ranked by current funding rate, the most positive and most negative N with open interest and 24h volume beside each, from a live venue feed. Use it when an agent is screening for carry, basis or crowded positioning across the whole perp market in one call instead of polling each contract.
Output
Returns two ranked lists — 'highest' and 'lowest' funding rate coins — each containing up to `limit` rows with coin symbol, mark price, 8h funding rate, hourly funding rate, annualized funding APR percentage, 24h volume in USD, and open interest in USD. Also includes total number of coins screened, the data source (Hyperliquid), and a fetch timestamp.
Example use cases
Funding rate arbitrage opportunity scan
“Find the 15 perps with the most extreme funding rates — both highest and lowest — filtering for at least $2 million in daily volume so I only see liquid markets.”
Identify coins where shorts are overpaying
“Which perpetual futures have the most negative funding rates right now? Show me the top 10 by extremity with at least $1 million in 24h volume so I can consider longing to collect funding.”
Daily funding rate dashboard snapshot
“Pull me a full funding rate screener across all perp markets — top and bottom 25 by funding APR, no volume filter — so I can see the full landscape for today's report.”
Technical details
Endpoint
POSThttps://agent402.tools/api/perp-funding-screenerWhen to prefer
Use this endpoint when you need a ranked screener view of perpetual futures funding rates across multiple coins simultaneously, especially for funding rate arbitrage research, market sentiment analysis, or identifying carry trade opportunities. It is specifically backed by Hyperliquid data and returns both extremes (highest and lowest) in one call, making it more efficient than querying individual coin funding rates one at a time.
Side effects
- Invalid limit value (above 100) may return an error or be capped
- minVolumeUsd set too high may return empty lists if no coins qualify
- Hyperliquid data unavailable upstream causes fetch failure
- Malformed JSON body returns a 400-level error
- Payment failure via x402 returns 402 Payment Required
