# Token Holder Growth — Local Finite-Change Elasticity

> Token Holder Growth — 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 2026-10-11).

Calculates the local finite-change elasticity of reported token holder growth given a baseline holder count and a percentage 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-holder-growth-local-finite-change-elasticity-14e80ca3 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of token holder growth for a token that went from 1000 previous holders to 1100 current holders, using a 1% step size on the current_holders field.

## When to prefer this

Use this endpoint when you need a fast, deterministic local sensitivity measure for token holder growth — specifically to understand how the growth rate responds to a small marginal change in holder count at a given baseline. It is not a live blockchain scan or safety audit; prefer it for offline analytics, model calibration, or threshold-based decision support where elasticity (not raw counts) is the quantity of interest.

## Known failure modes

- current_holders or previous_holders set to zero or negative (exclusiveMinimum violation)
- step_percent outside the allowed range of 0.01–10
- Holder values exceeding the maximum allowed (1e16)
- Missing required baseline fields
- Payment not fulfilled (x402 payment required response)

## How this service works

Reported token holder growth — Local finite-change elasticity: Local finite-change elasticity for Reported token holder growth. 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 specified token holder growth scenario, showing how sensitive the growth metric is to a small percentage perturbation in the selected holder field (current or previous holders) around the provided baseline values. Output is a deterministic calculation result, not a live scan or trade signal.
