# Reported Top-Holder Group Share — Base-100 Rebase Report

> Reported Top-Holder Group 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 2026-10-23).

Computes a Base-100 rebased index of a token's top-holder group share across a time series of supplied observations, anchored to a chosen base row.

## 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-top-holder-group-share-base-100-rebase-report-1e7b113f -d '<json body>'
```

Example prompt: I have a series of top-holder snapshots for a token — give me a base-100 rebase report where the first observation (index 0) is the anchor, using these rows: group_tokens 400000 with circulating 1000000, then 440000 with 1100000, then 380000 with 950000.

## When to prefer this

Choose this endpoint when you have a pre-collected time series of top-holder token counts and circulating supply figures and need a deterministic, caller-anchored Base-100 index to compare concentration levels across periods. It is not a live blockchain scan — it works purely on caller-supplied rows, making it ideal for reproducible, offline analysis pipelines or backtesting holder concentration trends without requiring real-time chain access.

## Known failure modes

- circulating_tokens must be greater than 0 (exclusiveMinimum); zero value returns validation error
- rows array must contain at least 2 items; single-row input rejected
- base_index must be within 0 to (number of rows - 1); out-of-range value causes error
- group_tokens or circulating_tokens exceeding 1e16 rejected as out of bounds
- Missing required fields group_tokens or circulating_tokens in any row causes schema validation failure
- Payment of 0.01 USDC via x402 required; unpaid requests return 402 response

## How this service works

Reported top-holder group share — Base-100 rebase report: Base-100 rebase report for Reported top-holder group 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

A Base-100 rebased index series showing how the top-holder group share (group_tokens / circulating_tokens) has moved relative to the chosen anchor observation. Each input row yields a rebased index value — 100 at the base row, above 100 if concentration increased, below 100 if it decreased. Deterministic, based solely on supplied data; not a live scan or safety recommendation.
