How this service works
Token bid-ask spread — Named scenario comparison: Named scenario comparison 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 named scenario comparison report.
Output
A deterministic named scenario comparison report showing the computed bid-ask spread for each labelled scenario versus the baseline, including spread values and relative deltas — not a live market scan or trade recommendation.
Example use cases
Market maker spread stress test
“I have a baseline token quote of bid 0.98 and ask 1.02. Run a named scenario comparison with two alternatives: 'Bear pressure' where the bid drops to 0.94, and 'Bull rally' where the ask rises to 1.08 — show me how the spread changes in each case.”
Pre-trade spread sanity check
“Before I place this order, compare my current spread — baseline bid 50.00 ask 50.20 — against a scenario called 'slippage scenario' where the ask widens to 50.50, and tell me the spread difference.”
Liquidity scenario planning
“Model two named spread scenarios against a baseline of bid 0.995 ask 1.005: one called 'Low liquidity' with bid 0.980 ask 1.020, and one called 'High liquidity' with bid 0.999 ask 1.001. Which scenario has the tightest spread?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-quote-spread-scenario?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to deterministically compare how bid-ask spread metrics change across multiple named hypothetical scenarios relative to a fixed baseline — ideal for pre-trade analysis, market-maker scenario planning, or threshold-based spread monitoring. Prefer it over single-calculation endpoints when you have two or more labelled pricing alternatives to evaluate simultaneously.
Side effects
- Ask price lower than or equal to bid price (invalid spread geometry) causing rejection
- Scenario array empty or exceeding 20 items limit
- Missing required 'label' or 'overrides' fields in a scenario object
- Bid or ask value of zero or negative, violating exclusiveMinimum constraint
- Overrides object submitted with no properties, violating minProperties:1
