# Token Drawdown from Supplied Peak — Local Finite-Change Elasticity

> Token Drawdown from Supplied Peak — Local Finite-Change Elasticity is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Computes the local finite-change elasticity of token price drawdown from a supplied peak, given a baseline peak price, current price, and a percentage step size.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability token-drawdown-from-supplied-peak-local-finite-change-elasticity-73da93eb -d '<json body>'
```

Example prompt: Can you calculate the local finite-change elasticity of a token's drawdown from its peak price, given a peak of $2.00 and a current price of $1.50, using a 1% step size on the peak_price field?

## When to prefer this

Use this endpoint when you need a deterministic, low-cost ($0.01 USDC) local finite-change elasticity estimate for a token's drawdown from its peak, given only two supplied price observations. Prefer it over broader analytics APIs when you specifically want a bounded elasticity figure (not a live market scan, not a recommendation) and you already know the peak and current prices. Best suited for offline or post-hoc quantitative analysis of token price behavior.

## Known failure modes

- Invalid or missing peak_price / current_price (must be positive non-zero numbers)
- current_price exceeding peak_price may produce unexpected or degenerate elasticity values
- step_percent outside the allowed range [0.01, 10] returns a validation error
- Missing required baseline object causes a schema validation failure
- Upstream engine unavailability returns a 5xx error

## How this service works

Token drawdown from supplied peak — Local finite-change elasticity: Local finite-change elasticity for Token drawdown from supplied peak. 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 token drawdown from the supplied peak. Returns a numeric elasticity value (or threshold verdict) indicating how the drawdown metric changes in response to a small finite percentage step in the specified price field, based solely on the supplied baseline price observations. Not a live scan, safety proof, or trade recommendation.
