How this service works
Token bid-ask spread — Local finite-change elasticity: Local finite-change elasticity 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 local finite-change elasticity report.
Output
A bounded local finite-change elasticity report for the selected field (bid or ask) of the token's bid-ask spread, computed deterministically from the supplied baseline prices and step percentage. Returns a numeric elasticity value or threshold verdict, not a live market scan or trade recommendation.
Example use cases
Spread sensitivity check before trade
“Before I place this token order, can you run a local finite-change elasticity calculation on the ask side using a baseline bid of 0.95 and ask of 1.05 with a 0.5 percent step, so I know how sensitive the spread is?”
Comparing bid vs ask elasticity
“Run two elasticity reports for me — one for the bid field and one for the ask field — both using a baseline of bid 0.97 and ask 1.03 with a 2 percent step, so I can compare which side is more elastic.”
Automated market monitoring alert threshold
“Check the bid-ask spread elasticity for this token using baseline bid 0.90 and ask 1.10 at a 1 percent step, and tell me the elasticity value so I can decide if it crosses my alert threshold.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-quote-spread-elasticity?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, single-point local elasticity measure for a token's bid-ask spread from your own supplied quote observations, rather than a live market data scan or a full scenario grid. It is ideal when you have a known baseline and want a fast, cheap ($0.01 USDC) finite-difference sensitivity estimate for the spread on either the bid or ask side.
Side effects
- Invalid field value (not 'bid' or 'ask') returns a validation error
- Baseline bid or ask at or below zero returns a minimum-value constraint error
- step_percent outside the 0.01–10 range returns a bounds error
- Missing or malformed baseline object returns a schema validation error
- Payment not included or insufficient USDC causes a 402 payment required response
