# Token Holder-Address Density — Benchmark Correlation

> Token Holder-Address Density — Benchmark Correlation 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 correlation between token holder-address density (holders per million USD market cap) and provided benchmark values for a supplied set of token 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 token-holder-address-density-benchmark-correlation-dac0245c -d '<json body>'
```

Example prompt: Can you run a benchmark correlation on token holder-address density for these observations — holders of 1000 and 1100 with market caps of $2M and $2.2M — and compare against benchmark values of 10, 20, 30, and 40?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) deterministic benchmark correlation specifically for token holder-address density (holders per million USD market cap) against a custom reference series. Prefer it over general statistics APIs when your data is already structured as holder/market-cap pairs and you want a pre-configured correlation preset tuned for on-chain token metrics.

## Known failure modes

- Fewer than 2 rows provided — minimum of 2 observation rows required
- Fewer than 2 benchmark values — minimum of 2 benchmarks required
- Zero or negative holder count or market cap — both must be positive non-zero numbers
- Exceeding 200 rows or 200 benchmark values — array size limits enforced
- Missing required fields (holders or market_cap_usd) in any row — validation error returned
- Payment not included or insufficient — endpoint requires $0.01 USDC per call via x402

## How this service works

Token holder-address density — Benchmark correlation: Benchmark correlation 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 benchmark correlation report.

## Output

A bounded benchmark correlation report showing how the supplied token holder-address density observations (holders per million USD market cap) correlate with the provided benchmark series. Includes a deterministic correlation coefficient and/or a caller-threshold verdict. Does not represent a live scan, safety proof, or trade recommendation.
