# Token Holder-Address Density Base-100 Rebase Report

> Token Holder-Address Density 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 token holder-address density (holders per million of market cap) across a series of observations, anchored to a chosen base row.

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-address-density-base-100-rebase-report-3c8008c9 -d '<json body>'
```

Example prompt: Can you compute a Base-100 rebased holder-address density report for this token data — I have 4 observations: holders 1000 with market cap $2M, holders 1100 with market cap $2.2M, holders 1000 with market cap $2M, and holders 1100 with market cap $2.2M — use the first row (index 0) as the base?

## When to prefer this

Choose this endpoint when you have a time-series or multi-observation dataset of token holder counts and market caps and need a deterministic, normalized Base-100 index of holder-address density. It is ideal for benchmarking holder concentration relative to a specific reference point without needing live blockchain access. Prefer it over raw ratio calculations when you need a standardized, rebased series suitable for comparison or reporting. Not suitable for real-time on-chain data retrieval, safety audits, or trade signals.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 observations required
- base_index out of range — must be within 0 to (number of rows - 1)
- holders or market_cap_usd set to zero or negative — both require exclusiveMinimum > 0
- More than 200 rows submitted — exceeds maxItems limit
- Malformed row objects missing required holders or market_cap_usd fields
- Payment not included or insufficient — endpoint requires $0.01 USDC via x402 protocol

## How this service works

Token holder-address density — Base-100 rebase report: Base-100 rebase report for Token holder-address density. 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 Base-100 rebased series of holder-address density (holders per million USD of market cap), anchored to the selected base index row. Each row in the input receives a normalized index score relative to the base. May include a deterministic threshold verdict (e.g. above/below baseline). Does not perform live blockchain scanning or provide safety/trade recommendations.
