How this service works
Statistical arbitrage — cointegrated pairs with z-score signals across crypto, equities, forex and DeFi. For quant and trading agents.
Output
Returns a ranked list of cointegrated asset pairs with z-score signals indicating how far the spread has deviated from its mean, along with correlation statistics, spread metrics, and directional signals indicating long/short positioning across crypto, equities, forex, and DeFi assets
Example use cases
DeFi spread mean-reversion opportunities
“Find me the cointegrated token pairs in DeFi that have the widest spreads right now — I want to identify which ones are most likely to snap back to their historical relationship soon.”
Forex pairs trading entry signals
“What forex pairs currently show strong cointegration with z-scores between 1.5 and 2.5? I'm looking for setups where the spread hasn't gotten too extreme yet but is starting to deviate from equilibrium.”
Cross-asset class arbitrage setup screening
“Can you show me cointegrated pairs that span across different asset classes — like crypto correlated with equities or commodities with forex — and flag any with unusual spread behavior I can trade?”
Technical details
Endpoint
GEThttps://arbipulse.vercel.app/api/pairsWhen to prefer
Use this endpoint when you need statistical arbitrage signals based on cointegration and z-score analysis rather than simple price differentials. Best suited for mean-reversion strategies where two assets have a long-run equilibrium relationship. Prefer this over simple CEX spot arbitrage endpoints when you want mathematically grounded pairs trading signals with entry/exit z-score thresholds rather than one-directional price gap trades.
Side effects
- Insufficient price history for cointegration test — pair returned with low confidence score
- Asset not found or ticker not recognized — 404 or empty pair result
- Market data feed unavailable — stale or missing price data warning
- No cointegrated pairs found for given parameters — empty results set
- Rate limit or payment failure — 402 payment required
