# Token Buy Volume Fraction — Base-100 Rebase Report

> Token Buy Volume Fraction — Base-100 Rebase Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Calculates a Base-100 rebased index of token buy volume fraction (buy volume as a share of total volume) across a time series of up to 200 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-base-100-rebase-report-6d222ddf -d '<json body>'
```

Example prompt: I have 4 rows of buy and sell volume data — buy volumes of 60000, 66000, 60000, 66000 and sell volumes of 40000, 44000, 40000, 44000 — can you rebase the buy volume fraction to a Base-100 index starting from the first row and give me the report?

## When to prefer this

Choose this endpoint when you need a deterministic, normalized Base-100 index of buy volume fraction over a supplied time series — particularly for token market analysis, period-over-period buy pressure comparison, or cross-session normalization. It is not a live scanner or safety checker; prefer it over raw ratio calculations when you need rebased, comparable index values anchored to a specific reference period.

## Known failure modes

- Fewer than 2 rows provided — minimum minItems:2 is required
- buy_volume or sell_volume is zero or negative — exclusiveMinimum:0 enforced
- base_index out of range — must be between 0 and (number of rows minus 1)
- More than 200 rows submitted — maxItems:200 exceeded
- Non-numeric volume values cause schema validation failure
- Payment failure via x402 protocol results in 402 response and no report

## How this service works

Token buy volume fraction — Base-100 rebase report: Base-100 rebase report 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 base-100 rebase report report.

## Output

A deterministic Base-100 rebased series showing the token buy volume fraction (buy_volume / (buy_volume + sell_volume)) for each input row, normalized so that the value at the chosen base_index equals 100. The report reflects only the supplied observations and does not constitute a live scan, safety proof, or trade recommendation.
