How this service works
Token bid-ask spread — Weighted result mean: Weighted result mean 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 weighted result mean report.
Output
A single weighted mean value representing the average bid-ask spread across the supplied token price observations, computed deterministically from the provided bid/ask pairs and their associated weights. No live market scanning or trade recommendation is included.
Example use cases
Liquidity quality check across time slots
“I have 6 bid-ask snapshots for a token taken at different times of day — bids [0.99, 1.05, 1.10, 0.97, 1.02, 1.08] and asks [1.01, 1.07, 1.13, 0.99, 1.04, 1.11] — and I want to weight recent snapshots more heavily with weights [1, 1, 2, 2, 3, 3]. Give me the weighted mean spread.”
Comparing spread across market regimes
“Can you compute the weighted mean bid-ask spread for this token during a volatile period? I have 3 observations: bids [0.95, 1.20, 0.88] and asks [1.05, 1.35, 0.98], all equally weighted at [1, 1, 1].”
Aggregating venue quotes for best spread estimate
“I'm pulling quotes from 5 different venues for the same token — bids [1.00, 1.001, 0.999, 1.002, 0.998] and asks [1.010, 1.012, 1.009, 1.011, 1.008] — and I want to weight the most liquid venues more: weights [3, 5, 2, 4, 1]. What's the weighted mean spread?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-quote-spread-weighted-mean?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, weighted aggregation of bid-ask spread observations for a token and already have the raw bid/ask data in hand. Prefer it over raw spread calculators when different observations should contribute unequally to the result (e.g. by volume, recency, or venue quality). It is not a live market scanner or a trade signal — use it for post-hoc analysis, reporting, or pre-trade spread benchmarking from collected quote data.
Side effects
- Fewer than 2 rows provided — minimum of 2 bid/ask observation pairs required
- Weights array length does not match rows array length — arrays must be equal in length
- Bid or ask value is zero or negative — all prices must be strictly positive
- Ask value less than or equal to bid value for a row — inverted spread not supported
- Row count exceeds 200 maximum items limit
- Weight value exceeds maximum of 1,000,000,000,000
