How this service works
Token bid-ask spread — Record ranking: Record ranking 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 record ranking report.
Output
Returns a deterministic ranking report of the supplied token bid-ask spread observations, identifying which rows represent record (extreme) spread values — such as the widest or narrowest spreads — based on a calculated verdict against the caller-supplied data. Does not include live market scans, safety assessments, or trade recommendations.
Example use cases
Finding widest spread in token portfolio
“I'm monitoring several tokens and want to know which ones have the most extreme bid-ask spreads. Can you rank these observations for me: bid 0.98 ask 1.02, bid 2.10 ask 2.50, bid 0.50 ask 0.51, bid 100.0 ask 105.0?”
Pre-trade spread quality check
“Before I execute trades, I want to rank these token quotes by their spreads to see which are record outliers: bid 1.00 ask 1.01, bid 0.90 ask 0.95, bid 50.00 ask 52.00, bid 10.00 ask 10.05, bid 0.01 ask 0.02.”
Backtesting spread extremes in historical data
“I have a set of historical token bid-ask pairs from yesterday's session — can you rank them and flag any record spread values? Pairs are: bid 1.10 ask 1.12, bid 0.88 ask 0.92, bid 5.00 ask 5.50, bid 0.30 ask 0.31.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-quote-spread-rank?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a fixed, caller-supplied set of token bid-ask observations and need a deterministic ranking or record identification of spreads within that dataset. It is not a live market scanner or real-time feed — it operates only on the rows you submit. Prefer this over general analytics tools when you specifically need spread-based record ranking with a bounded, affordable per-call cost.
Side effects
- Fewer than 2 rows supplied — minimum of 2 observations required
- More than 200 rows supplied — maximum batch size exceeded
- Missing required 'bid' or 'ask' field in one or more rows — validation error
- bid or ask value is zero or negative — exclusiveMinimum constraint violated
- ask or bid value exceeds maximum allowed (10^16) — out-of-range error
- Payment of 0.01 USDC not provided or rejected — 402 Payment Required
