# Token Buy Volume Fraction — Ordered Trend Analysis

> Token Buy Volume Fraction — Ordered Trend Analysis 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).

Analyzes the ordered trend of buy volume fraction (buy volume as a share of total volume) across a sequence of token trading observations.

## 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-buy-volume-fraction-ordered-trend-analysis-b8d2e667 -d '<json body>'
```

Example prompt: Can you run an ordered trend analysis on these token buy and sell volume observations: [{buy_volume: 60000, sell_volume: 40000}, {buy_volume: 66000, sell_volume: 44000}, {buy_volume: 72000, sell_volume: 38000}, {buy_volume: 80000, sell_volume: 35000}] and tell me if the buy volume fraction is trending up?

## When to prefer this

Use this endpoint when you have a sequence of token buy and sell volume observations and need a deterministic, reproducible ordered trend analysis of the buy volume fraction. Prefer this over general-purpose statistics tools when you want a structured, bounded report with optional threshold verdicts at a very low cost ($0.01 USDC per call). Not suitable for live streaming data, real-time scanning, or as a standalone trade recommendation engine.

## Known failure modes

- Fewer than 2 rows supplied — minimum is 2 observations
- More than 200 rows supplied — maximum is 200 observations
- buy_volume or sell_volume is zero or negative — both must be strictly positive
- Malformed row objects missing required buy_volume or sell_volume fields
- Payment not attached or insufficient (requires 0.01 USDC via x402)

## How this service works

Token buy volume fraction — Ordered trend analysis: Ordered trend analysis for Token buy volume fraction. 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 ordered trend analysis report.

## Output

A deterministic ordered trend analysis report for the buy volume fraction metric (buy_volume / (buy_volume + sell_volume)) across the supplied sequence of observations, including trend direction and optionally a caller-threshold verdict. This is a bounded analysis report, not a live market scan or trade recommendation.
