Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/FundingRateAgent/get_symbol_oi_and_fundingWhen to prefer
Use this endpoint when you need both open interest trend context AND the current funding rate for a Binance perpetual futures symbol in a single call. Prefer this over the standalone funding-rate endpoint when you want historical OI context (7-day 4-hour trend) alongside spot funding data, useful for assessing crowded trades or funding arbitrage opportunities.
Side effects
- Unknown or unsupported symbol returns an error or empty result
- Symbol provided without USDT suffix may be normalized automatically, but ambiguous tickers could fail
- Binance API downtime or rate limits may cause temporary unavailability
- Network timeout for slow connections
- Incorrect symbol format (e.g. lowercase) may return no data
