How this service works
Live crypto and stock market console: OwlView charts, TBO breakout signals, order books from 34 exchanges, ETF flows, funding, liquidations and Fed odds.
Output
A JSON object containing the coin ticker, a breakdown of funding rates by exchange (e.g. Bybit: 0.00008, Binance: 0.0001), and total open interest in USD across the aggregated market (e.g. $6.1 billion for SOL).
Example use cases
Pre-trade leverage check for SOL
“Before I enter a long position on SOL, can you check the current funding rates on Binance and Bybit and tell me the total open interest so I can gauge how crowded the trade is?”
Monitoring funding spikes for ETH
“Set up a check on ETH funding rates and open interest — I want to know if funding goes extremely positive or negative, which might signal an overleveraged market.”
Comparing funding environment across coins
“Can you pull the current funding rates and open interest for BTC and compare them to SOL so I can see which perpetual market is more expensive to hold a long in?”
Technical details
Endpoint
GEThttps://owlchart.com/api/x402/funding-oi?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time perpetual futures funding rates disaggregated by exchange alongside aggregated open interest for a specific cryptocurrency. It is ideal for pre-trade analysis, monitoring market leverage conditions, or detecting extreme funding environments that may signal crowded trades. Prefer this over generic market data APIs when exchange-level funding rate granularity and OI context are both needed in a single call.
Side effects
- Missing or invalid 'coin' query parameter returns an error
- Unsupported or unrecognized coin ticker returns empty or error response
- Payment not processed (402) if x402 payment header is missing or invalid
- Rate limit exceeded if too many calls are made in a short window
- Temporary data gaps if upstream exchange feeds are unavailable
