# Unique Token Traders per Trade — Adjacent Period Changes

> Unique Token Traders per Trade — Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Computes period-over-period changes in the ratio of unique token traders to trade count across a sequence of supplied data 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 unique-token-traders-per-trade-adjacent-period-changes-6d10cf33 -d '<json body>'
```

Example prompt: I have four periods of token trading data — period 1 had 1000 trades with 100 unique traders, period 2 had 1100 trades with 110 unique traders, period 3 had 1000 trades with 100 unique traders, period 4 had 1100 trades with 110 unique traders — can you calculate the adjacent period changes in the unique traders per trade ratio for me?

## When to prefer this

Choose this endpoint when you have a sequence of (unique_traders, trade_count) pairs across consecutive time periods and need a deterministic, cheap computation of how the unique-traders-per-trade ratio changed period over period. It is not a live market data feed, sentiment tool, or safety scanner — it is a focused calculation over caller-supplied historical rows. Ideal for periodic batch analytics jobs, reporting pipelines, or agent workflows that already hold the raw trading stats and need the delta analysis computed without standing up custom code.

## Known failure modes

- Fewer than 2 rows supplied — minimum rows requirement not met
- trade_count of 0 or negative submitted — exclusiveMinimum violation
- More than 200 rows supplied — maxItems exceeded
- Missing required fields unique_traders or trade_count in any row — schema validation failure
- Extremely large numbers causing floating-point precision issues in ratio computation

## How this service works

Unique observed token traders per trade — Adjacent period changes: Adjacent period changes for Unique observed token traders per trade. 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 adjacent period changes report.

## Output

A bounded report of adjacent period changes for the unique traders per trade ratio, showing how the metric shifted between each consecutive pair of supplied rows — deterministic, based purely on the caller-supplied trade_count and unique_traders values, not a live market scan or safety recommendation.
