How this service works
Token bid-ask spread — Benchmark correlation: Benchmark correlation for Token bid-ask spread. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded benchmark correlation report.
Output
Returns a bounded benchmark correlation report containing the computed correlation coefficient between the derived bid-ask spread series and the provided benchmark values, produced via deterministic calculation. The report is scoped to the supplied observations and represents a statistical relationship metric, not a live market scan or trade signal.
Example use cases
Token liquidity vs index correlation check
“I have four token quote snapshots with bids [0.95, 1.00, 1.05, 1.10] and asks [1.00, 1.06, 1.11, 1.16] — can you tell me how correlated those bid-ask spreads are with the benchmark values [100, 200, 300, 400]?”
Market maker spread tracking
“We're monitoring a market maker's quoted spreads over 6 periods: bids [0.99, 0.98, 1.01, 1.00, 0.97, 0.96] and asks [1.01, 1.02, 1.03, 1.02, 1.03, 1.04]. Can you benchmark-correlate those against our reference index [5, 10, 8, 12, 7, 9]?”
Pre-trade spread benchmark validation
“Before I place a large order, I want to check if recent token spreads are tracking our volatility benchmark — bids [2.00, 2.10, 1.90] and asks [2.05, 2.16, 1.96] against benchmark [30, 45, 20]. What's the correlation?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-quote-spread-correlation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible correlation coefficient between token bid-ask spread observations and a numeric benchmark series. It is ideal for quantitative analysis pipelines, pre-trade liquidity checks, or academic/research contexts where a statistically bounded verdict is needed rather than a live market scan or predictive recommendation. Prefer this over generic stats libraries when you need a packaged, priced microservice for auditability or cost-accounting per correlation report.
Side effects
- Fewer than 2 rows provided — minimum 2 bid/ask pairs required
- More than 200 rows provided — exceeds maxItems limit
- Benchmark array length does not match row count — mismatched series lengths
- Zero or negative bid or ask values — violates exclusiveMinimum:0 constraint
- Benchmark array shorter than 2 or longer than 200 items
- Non-numeric values in bid, ask, or benchmark arrays — schema validation failure
