# Token Buy Volume Fraction — Distribution Summary

> Token Buy Volume Fraction — Distribution Summary is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes a statistical distribution summary of the buy volume fraction (buy volume as a share of total volume) across a supplied set 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-distribution-summary-ea6c138a -d '<json body>'
```

Example prompt: Can you give me a distribution summary of the buy volume fraction across these 4 token observations — buy volumes of 60000, 66000, 60000, 66000 and sell volumes of 40000, 44000, 40000, 44000?

## When to prefer this

Choose this endpoint when you have a set of token trading observations with explicit buy and sell volumes and need a deterministic statistical distribution summary of the buy volume fraction. It is purpose-built for token market microstructure analysis and returns a bounded, reproducible report. Prefer it over generic statistics APIs when you specifically need buy-side volume share distribution in a crypto/token trading context, and over raw price feeds when you already have volume data and need summary statistics rather than raw values.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 observations required
- buy_volume or sell_volume of zero or negative — both must be strictly positive (exclusiveMinimum: 0)
- More than 200 rows supplied — array is capped at 200 items
- Missing required fields buy_volume or sell_volume in any row
- Volume values exceeding the maximum bound of 10^16
- Payment failure via x402 protocol — endpoint requires 0.01 USDC per call

## How this service works

Token buy volume fraction — Distribution summary: Distribution summary 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 distribution summary report.

## Output

A bounded distribution summary report covering statistical properties of the buy volume fraction (buy_volume / (buy_volume + sell_volume)) across all supplied row observations — including metrics such as min, max, mean, median, percentiles, and spread indicators. The result is deterministic and based solely on the supplied data, not a live market scan or trade recommendation.
