# Largest Reported Token Holder Share — Base-100 Rebase Report

> Largest Reported Token Holder Share — Base-100 Rebase Report 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).

Computes a Base-100 rebased index of the largest token holder's share relative to circulating supply across a series of observations.

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 largest-reported-token-holder-share-base-100-rebase-report-b5891196 -d '<json body>'
```

Example prompt: Give me a base-100 rebased report for the largest token holder share using these observations: holder_tokens [100000, 110000, 95000] and circulating_tokens [1000000, 1100000, 950000], with period 0 as the base index.

## When to prefer this

Choose this endpoint when you need a deterministic, normalized base-100 index of the largest token holder's share across multiple time periods or snapshots. It is suited for trend analysis, governance risk assessment, or concentration monitoring where you supply pre-collected holder and circulating supply figures and want a rebased comparison series. It is not appropriate for live on-chain scans, safety ratings, or trade recommendations.

## Known failure modes

- circulating_tokens must be greater than 0 (exclusiveMinimum); zero value will cause validation failure
- rows array must contain at least 2 items; single-row input rejected
- rows array cannot exceed 200 items
- base_index must be an integer between 0 and 199 and must reference a valid row index
- holder_tokens or circulating_tokens values exceeding 10^16 will be rejected
- malformed or missing required fields (holder_tokens, circulating_tokens) cause request rejection
- payment of 0.01 USDC must be included; missing or insufficient payment results in 402 error

## How this service works

Largest reported token holder share — Base-100 rebase report: Base-100 rebase report for Largest reported token holder share. 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 base-100 rebase report report.

## Output

Returns a deterministic Base-100 rebased index series representing the largest token holder's share relative to circulating supply across the supplied observation rows, anchored to the specified base_index period. Output reflects proportional changes in holder concentration, not a live scan or safety assessment.
