# Unique Token Traders Per Trade — Before & After Comparison

> Unique Token Traders Per Trade — Before & 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 2026-10-13).

Computes the ratio of unique traders to trade count for a token, comparing a 'before' snapshot to an 'after' snapshot to quantify change.

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-before-after-comparison-01d6f7b3 -d '<json body>'
```

Example prompt: Compare the unique traders per trade ratio for this token: before it had 100 unique traders across 1000 trades, and after it had 110 unique traders across 1100 trades — give me the before and after breakdown.

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible calculation of how the unique-traders-to-trade-count ratio changed between two discrete time periods for a specific token, and you only have pre-aggregated snapshot figures (not raw trade data). It is ideal for lightweight, cost-effective ($0.01 USDC) point-in-time comparisons rather than continuous monitoring or live scanning.

## Known failure modes

- trade_count of 0 or missing triggers validation error (exclusiveMinimum enforced)
- unique_traders exceeding maximum float precision may produce unexpected results
- malformed JSON body returns 400-level error
- payment failure or missing x402 payment header results in 402 Payment Required
- server-side engine overload may return 5xx

## How this service works

Unique observed token traders per trade — Before and after comparison: Before and after comparison 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 before and after comparison report.

## Output

A bounded before-and-after comparison report for the unique traders per trade metric, including the computed ratio for both the 'before' and 'after' states (unique_traders / trade_count), the delta between them, and a deterministic verdict or threshold classification. No live scan or trade recommendation is included.
