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.
Output
A JSON object with the altcoin base symbol, best lag in minutes, Pearson correlation coefficient, BTC momentum percentage over the lag window, implied next directional bias (up/down), and a confidence score — plus a human-readable note summarizing the relationship.
Example use cases
Example prompt
“What's the BTC lead-lag signal for SOL right now — how many minutes does SOL typically lag BTC, and is the implied next move up or down?”
Technical details
Endpoint
GEThttps://cryptojp.com/v1/leadlagWhen to prefer
Use this endpoint when an AI trading agent needs a real-time, quantified measure of how closely and with what time lag a specific altcoin follows BTC price movements, and wants an actionable directional bias derived from current BTC momentum. Prefer this over generic market data APIs when you specifically need lead-lag correlation intelligence rather than raw price data.
Side effects
- Missing or invalid 'symbol' query parameter returns an error response
- Symbol is BTC itself (endpoint only supports altcoins, not BTC)
- Payment not settled via x402 returns HTTP 402 Payment Required
- Symbol not supported or lacking sufficient data returns low confidence or error
- Rate limiting or server unavailability returns 5xx error
