> Token Top-Holder Group Share Distribution Summary 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 a distribution summary report showing the share of circulating supply held by a top-holder group, given supplied token observation rows.

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-top-holder-group-share-distribution-summary-92d95e6a -d '<json body>'
```

Example prompt: Give me a distribution summary of the top holder group share for this token — the group holds 400,000 tokens out of 1,000,000 circulating tokens; include a second snapshot where the group holds 440,000 out of 1,100,000.

## When to prefer this

Use this endpoint when you need a fast, deterministic distribution summary of how much of a token's circulating supply is held by a top-holder group, using your own supplied snapshot data. Prefer this over live on-chain scanners when you already have the token observation data and need a bounded, reproducible calculation rather than a real-time lookup. Best suited for due diligence, risk assessment, or trend analysis across multiple time-point snapshots.

## Known failure modes

- Input array has fewer than 2 rows — minimum 2 observations required
- circulating_tokens is zero or missing — exclusiveMinimum enforced
- group_tokens or circulating_tokens exceed maximum value of 10^16
- More than 200 rows supplied — maxItems limit exceeded
- Missing required fields group_tokens or circulating_tokens in any row — validation error
- Payment of 0.01 USDC not processed — x402 payment required error

## How this service works

Reported top-holder group share — Distribution summary: Distribution summary 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 distribution summary report.

## Output

A bounded distribution summary report detailing the share of circulating supply controlled by the reported top-holder group, computed deterministically from the supplied row observations. Includes concentration metrics derived from group_tokens vs circulating_tokens ratios across the provided snapshots. Not a live scan, safety proof, or trade recommendation.
