How this service works
Retrieve predicted funding rates through StableJack's agent-ready research API.
Output
Returns predicted funding rates for one or more cryptocurrency perpetual futures contracts, including the asset identifier, the forecasted funding rate value, and associated metadata such as direction and confidence, enabling agents to assess carry cost, market sentiment, and arbitrage opportunities.
Example use cases
Funding rate arbitrage signal detection
“Check StableJack's predicted funding rates for BTC and ETH perpetuals — I want to know if there's a big enough spread to consider a funding rate arbitrage trade.”
DeFi yield strategy optimization
“Pull the latest predicted funding rates across crypto perps from StableJack so I can figure out which assets to short on perps and earn funding in my delta-neutral strategy.”
Market sentiment analysis via funding
“Get me StableJack's predicted funding rates for the top 10 crypto perpetuals — high positive funding usually means crowded longs and I want to spot overheated assets before they correct.”
Technical details
Endpoint
POSThttps://ai.stable-jack.com/x402/tools/predicted_funding_ratesWhen to prefer
Choose this endpoint when you need forward-looking, AI-predicted funding rates rather than historical or real-time spot rates. Ideal for agents building delta-neutral strategies, carry trade signals, or market sentiment dashboards based on perpetual futures. Prefer over generic crypto data APIs when you need predictive rather than descriptive funding rate data, and when you want a research-grade signal from StableJack's model rather than raw exchange feeds.
Side effects
- Invalid or unsupported asset symbol returns an error or empty result
- Stale prediction data if the model has not been recently updated
- Payment failure (x402 protocol issue) results in 402 response with no data
- Rate limiting if too many calls are made in quick succession
- Network timeout if the upstream model inference takes too long
