# Unique Token Traders Per Trade — Sequential Input-Change Attribution

> Unique Token Traders Per Trade — 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 2026-10-14).

Computes a sequential input-change attribution report for the unique observed token traders per trade ratio, comparing before/after observation snapshots.

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-sequential-input-change-attribution-56f395c2 -d '<json body>'
```

Example prompt: Run a sequential input-change attribution on unique token traders per trade: before snapshot had 100 unique traders and 1000 trades, after snapshot had 110 unique traders and 1100 trades — give me the waterfall breakdown of what drove the ratio change.

## When to prefer this

Use this endpoint when you need a deterministic, bounded attribution analysis of how changes in unique trader count and trade volume drove a shift in the unique-traders-per-trade ratio between two specific observation snapshots for a token. Prefer it over generic analytics tools when you need a reproducible, caller-supplied-data waterfall calculation with no dependency on live market feeds or external data sources.

## Known failure modes

- trade_count of 0 or missing (exclusiveMinimum:0 enforced — will error)
- unique_traders or trade_count out of allowed range (0 to 1e16)
- Missing required fields in before or after objects
- Malformed JSON body — returns 4xx error
- Payment not processed — returns 402 Payment Required

## How this service works

Unique observed token traders per trade — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A deterministic sequential input-change attribution report showing how changes in unique_traders and trade_count inputs between the before and after snapshots contribute to the overall change in the unique traders per trade ratio, broken down in waterfall/attribution format. No live scan or safety judgment is included.
