# Token Buy-to-Sell Activity Ratio — Rolling Mean Report

> Token Buy-to-Sell Activity Ratio — Rolling Mean Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes a rolling mean of the buy-to-sell activity ratio across a supplied sequence of token trade observations using a configurable window size.

## 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-to-sell-activity-ratio-rolling-mean-report-5ca3ec33 -d '<json body>'
```

Example prompt: Can you compute a rolling mean of the buy-to-sell ratio for these token observations — buy counts [120, 132, 110, 145] and sell counts [80, 88, 75, 95] — using a window size of 2?

## When to prefer this

Use this endpoint when you have a discrete series of token buy and sell count observations and need a smoothed, rolling mean of the buy-to-sell ratio — particularly useful for trend analysis, momentum signals, or reducing noise in short time-series data. Prefer this over raw ratio lookup when you need windowed averaging rather than instantaneous ratios, and when your data is pre-collected (not a live feed).

## Known failure modes

- Fewer than 2 rows supplied — minimum row count not met
- sell_count of 0 in any row — division by zero in ratio calculation
- Window size exceeds number of supplied rows — insufficient data for rolling calculation
- buy_count or sell_count values outside allowed range (0 to 10^16)
- More than 200 rows supplied — exceeds maxItems limit
- Payment failure — 0.01 USDC not available or x402 protocol error

## How this service works

Token buy-to-sell activity ratio — Rolling mean report: Rolling mean report for Token buy-to-sell activity ratio. 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 rolling mean report report.

## Output

Returns a rolling mean series of the buy-to-sell activity ratio (buy_count / sell_count) computed across the supplied observation rows using the specified window size. Each value in the output represents the mean ratio over the preceding N observations defined by the window parameter.
