# Token Buy Volume Fraction — Single Calculation

> Token Buy Volume Fraction — Single Calculation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Calculates the buy volume fraction (buy volume share) of a token given buy and sell volume figures, returning a deterministic ratio or threshold verdict.

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 token-buy-volume-fraction-single-calculation-1a457102 -d '<json body>'
```

Example prompt: Calculate the buy volume fraction for a token that had 60,000 in buy volume and 40,000 in sell volume — what share of total volume is buying?

## When to prefer this

Use this endpoint when you need a fast, cheap, deterministic single-point calculation of buy volume fraction from raw buy and sell volume figures — ideal for real-time agent pipelines, pre-trade checks, or automated screening where you already have volume data and need only a ratio or threshold verdict. Prefer this over batch endpoints when evaluating a single token at a time.

## Known failure modes

- Missing buy_volume or sell_volume fields returns a validation error
- buy_volume or sell_volume of zero or negative values are rejected (exclusiveMinimum: 0)
- Values exceeding the maximum bound (1e16) are rejected
- Malformed JSON body returns a parse error
- Network or service unavailability returns a 5xx error

## How this service works

Token buy volume fraction — Single calculation: Single calculation 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 single calculation report.

## Output

Returns a deterministic numeric report of the buy volume fraction (buy volume divided by total volume), representing the share of trading activity attributable to buys. May also include a caller-threshold verdict indicating whether the fraction meets a specified threshold. No live scan or trade recommendation is provided.
