# Reported Token Holder Growth — Before and After Comparison

> Reported Token Holder Growth — Before and After Comparison 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).

Compares token holder growth rates between two time periods (before and after), computing growth metrics for each period and contrasting them deterministically.

## 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-token-holder-growth-before-and-after-comparison-ec86fcae -d '<json body>'
```

Example prompt: Compare my token's holder growth across two periods: before the airdrop we went from 1,000 to 1,100 holders, and after the airdrop we went from 1,100 to 1,210 holders — show me a before-and-after growth comparison.

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible comparison of token holder growth across exactly two time periods using supplied observations — not a live blockchain scan. Ideal when you already have holder count snapshots for a 'before' window and an 'after' window and want a structured growth delta report without manual calculation. Prefer this over live-scan analytics when you control the input data and need a low-cost ($0.01 USDC), instant, audit-friendly computation.

## Known failure modes

- Missing required fields (current_holders or previous_holders in either before or after objects) returns validation error
- Values of 0 or negative rejected due to exclusiveMinimum constraint
- Extremely large holder counts near the maximum boundary may produce edge-case results
- Payment not processed results in 402 response and no computation
- Swapped before/after values (after period smaller than before) may produce negative deltas that are valid but potentially confusing

## How this service works

Reported token holder growth — Before and after comparison: Before and after comparison for Reported token holder growth. 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 before and after comparison report.

## Output

A deterministic before-and-after comparison report showing token holder growth metrics for each period — including growth rates, holder counts, and a delta comparing the two windows — based solely on the supplied holder observations.
