# Token Position / FDV Local Finite-Change Elasticity

> Token Position / FDV 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 2026-10-14).

Computes the local finite-change elasticity of a token position relative to its fully diluted valuation (FDV), given a baseline position and FDV in USD 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-position-fdv-local-finite-change-elasticity-6b71dae3 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity for my token position: I have a $10,000 position_usd with an FDV of $4,000,000, using a 1% step — I want to see how elastic my position is relative to the FDV.

## When to prefer this

Choose this endpoint when you need a deterministic, offline computation of how a token position's sensitivity scales relative to FDV at a specific local point — particularly useful for portfolio risk sizing, tokenomics modeling, or pre-trade sensitivity analysis where you have a fixed baseline and want a bounded elasticity estimate without relying on live market data feeds.

## Known failure modes

- Missing or zero baseline values (position_usd or fdv_usd must be strictly positive)
- step_percent out of range (must be between 0.01 and 10)
- Invalid field enum value (must be 'position_usd' or 'fdv_usd')
- Malformed request body causing schema validation failure
- Payment not included or insufficient (requires 0.01 USDC via x402 protocol)

## How this service works

Token position relative to diluted value — Local finite-change elasticity: Local finite-change elasticity for Token position relative to diluted value. 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, bounded local finite-change elasticity report quantifying how the specified field (position_usd or fdv_usd) responds to a percentage-step perturbation relative to the token's fully diluted valuation. Returns a numeric elasticity coefficient and supporting computation details based solely on the supplied baseline observations — not a live market scan or trade recommendation.
