How this service works
Market-wide extreme funding (crowding / carry opportunities)
Output
A JSON array of perpetual markets exceeding the specified annualized funding threshold, each record containing the ticker symbol, current/1-day/7-day annualized funding rates, the dominant crowd side (long or short), and open interest in USD — enabling identification of carry opportunities and crowded positioning.
Example use cases
Funding carry trade opportunity scan
“Which perp markets have annualized funding above 200% right now? I want to see the top 30 sorted by extremity so I can identify the best carry trade setups.”
Short squeeze crowding alert
“Find me any perpetual futures markets where shorts are extremely crowded based on funding — I want to see the funding annualized over the last day and week too, not just the current rate.”
Market-wide funding regime overview
“Give me a broad snapshot of all crypto perps with extreme funding today — both wildly positive and wildly negative — so I can understand where the market crowding is concentrated right now.”
Technical details
Endpoint
GEThttps://api.tradesonar.io/v1/funding/extreme?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a market-wide sweep for extreme funding conditions rather than analysis of a single market. It is the right choice for scanning for carry trade setups, identifying crowded positioning across the entire derivatives landscape, or building alerts for abnormal funding regimes. Prefer the single-market funding endpoint when you need deeper term structure or regime analysis for one specific ticker.
