# Token Fully Diluted Value — Local Finite-Change Elasticity

> Token Fully Diluted Value — 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 2026-10-16).

Computes the local finite-change elasticity of a token's fully diluted value (FDV) with respect to a specified field (price or supply), given a baseline and a step size.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-fully-diluted-value-local-finite-change-elasticity-978c7cfa -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of a token's fully diluted value using a baseline price of $2 per token and 2,000,000 fully diluted tokens, varying the price_usd field with a 1% step — give me the elasticity report.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, mathematically precise local elasticity measurement for a token's fully diluted value at a specific baseline — not a live market scan, safety audit, or price prediction. Ideal for pre-trade sensitivity analysis, tokenomics modeling, or comparing FDV responsiveness across different baseline scenarios without needing real-time market data.

## Known failure modes

- Missing or zero baseline values (price_usd or fully_diluted_tokens must be positive non-zero)
- step_percent out of allowed range (must be between 0.01 and 10)
- Invalid field enum value (must be 'price_usd' or 'fully_diluted_tokens')
- Payment not included or insufficient (requires 0.01 USDC via x402 protocol)
- Malformed request body returns validation error

## How this service works

Token fully diluted value — Local finite-change elasticity: Local finite-change elasticity for Token fully 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

Returns a bounded local finite-change elasticity report for the token's fully diluted value: a numeric elasticity coefficient indicating how much the FDV changes (proportionally) for the specified percentage step in the chosen input field, computed deterministically from the supplied baseline observations.
