How this service works
Token observed price change — Local finite-change elasticity: Local finite-change elasticity for Token observed price change. 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 deterministic local finite-change elasticity report for the supplied token price observations. The report quantifies how the observed price change responds to a small finite step in the chosen field (current_price or previous_price), expressed as a bounded elasticity value derived from the baseline prices and step percentage. No live market data, trade recommendations, or safety guarantees are included.
Example use cases
Token volatility sensitivity check
“I want to know how elastically a token responded to a recent price move — it went from $0.80 to $0.96. Can you calculate the local finite-change elasticity using a 0.5% step on the current price?”
DeFi arbitrage sensitivity analysis
“Before deciding whether to act on a price gap, compute the finite-change elasticity for a token that moved from $500 to $520, using a 2% step on the current_price field.”
Portfolio risk metric calculation
“For my risk model, calculate the local elasticity of a token's price change where previous price was $10.00 and current price is $10.75, using a 1% step on the previous_price field.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-token-price-change-elasticity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, single-call elasticity metric derived purely from two supplied token price observations and a configurable step percentage. It is well-suited for agents performing quantitative price sensitivity analysis, building risk models, or evaluating token price responsiveness without requiring live market feeds or probabilistic models.
Side effects
- Missing or zero-value prices cause validation errors since both current_price and previous_price must be strictly positive
- step_percent outside the allowed 0.01–10 range returns a validation error
- Omitting both baseline prices falls back to defaults which may not reflect the caller's intended scenario
- Payment failure or insufficient USDC balance results in a 402 response and no report is generated
