How this service works
Pay-per-call crypto market-intelligence API for autonomous AI trading agents. Funding-rate, BTC lead-lag and trend/chop regime signals, settled in USDC over x402.

Returns a JSON object with the asset symbol, basis percentage, spot price, perp mark price, market structure label (contango or backwardation), a human-readable interpretation of what the structure means for longs/shorts, and the annualized funding rate percentage.
Example use cases
Example prompt
“What's the current basis and funding rate for ETH — is it in contango or backwardation, and is it expensive to hold a long perp position right now?”
Technical details
Endpoint
GEThttps://cryptojp.com/v1/basisWhen to prefer
Use this endpoint when an AI trading agent needs real-time funding rate and basis intelligence for a specific crypto asset to decide whether to enter, hold, or exit a leveraged perpetual futures position. Prefer this over generic price feeds when the agent specifically needs carry cost, market structure regime, or funding rate signals.
