# Reported Token Holder Growth — Weighted Result Mean

> Reported Token Holder Growth — Weighted Result Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Calculates the weighted arithmetic mean of token holder growth rates across multiple observation rows, using caller-supplied weights.

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 reported-token-holder-growth-weighted-result-mean-2b3fc5df -d '<json body>'
```

Example prompt: I have four token holder snapshots — (1100 from 1000), (1210 from 1100), (1100 from 1000), (1210 from 1100) — and I want a weighted mean of the growth rates using weights 1, 2, 1, 2. Can you compute that for me?

## When to prefer this

Choose this endpoint when you need a deterministic, weighted aggregation of token holder growth rates across multiple time periods or observation windows and want a single summary metric. It is purpose-built for token-holder growth specifically (as opposed to generic growth or inventory metrics) and supports up to 200 rows with per-row weighting, making it ideal for multi-period trend summarization or importance-weighted portfolio rollups.

## Known failure modes

- Mismatched array lengths between rows and weights returns a validation error
- rows array with fewer than 2 items is rejected
- previous_holders value of 0 causes division error (excluded by exclusiveMinimum constraint)
- weights containing negative values may be rejected
- payload exceeding 200 rows is rejected with a size limit error
- Missing required fields current_holders or previous_holders returns schema validation failure

## How this service works

Reported token holder growth — Weighted result mean: Weighted result mean 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 weighted result mean report.

## Output

Returns a single weighted result mean value representing the aggregated token holder growth rate across the supplied observation rows, computed deterministically from caller-provided current_holders, previous_holders, and weights arrays. The result reflects a bounded, reproducible calculation — not a live scan or trading recommendation.
