# Token Holder-Address Density Sequential Input-Change Attribution

> Token Holder-Address Density Sequential Input-Change Attribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes a sequential input-change (waterfall) attribution report showing how changes in token holder count and market cap affect the holders-per-million metric between two states.

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-sequential-input-change-attribution-7a2bac06 -d '<json body>'
```

Example prompt: Run a sequential input-change attribution report for token holder density: before it had 1000 holders and a $2,000,000 market cap, and after it had 1100 holders and a $2,200,000 market cap — show me how much each input change contributed to the shift in holders-per-million.

## When to prefer this

Choose this endpoint when you need a deterministic, decomposed attribution of what drove a change in token holder-address density (holders per million) between two discrete snapshots, and you already have the holder count and market cap figures for both states. It is not a live scanner or safety audit — prefer it for post-hoc analysis, reporting, and quantifying the relative contribution of holder growth vs market cap movement.

## Known failure modes

- Zero or negative holder count or market cap values rejected (exclusiveMinimum:0)
- Missing required 'holders' or 'market_cap_usd' in before/after objects returns validation error
- Payment not fulfilled (x402 protocol) results in 402 response with no report
- Extremely large values near the maximum boundary may produce edge-case numeric results
- If before and after states are identical, attribution values will all be zero

## How this service works

Token holder-address density — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

Returns a bounded sequential input-change (waterfall) attribution report detailing how each input variable (holder count and market cap) contributed to the change in the token holders-per-million density metric between the before and after states; may include a deterministic threshold verdict. No live scan or trade recommendation is provided.
