# Token Net Buy-Count Balance — Weighted Result Mean

> Token Net Buy-Count Balance — Weighted Result Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Computes a weighted mean of the net buy-count balance (buy_count vs sell_count ratio) across multiple token observations using caller-supplied weights.

## 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-net-buy-count-balance-weighted-result-mean-7870ebfd -d '<json body>'
```

Example prompt: I have four token observation windows with buy counts [120, 132, 120, 132] and sell counts [80, 88, 80, 88] — can you compute the weighted mean of the net buy-count balance using weights [1, 2, 1, 2] to give more importance to the recent windows?

## When to prefer this

Use this endpoint when you need a single deterministic weighted aggregate of token net buy pressure across multiple observation windows and want control over per-row importance via explicit weights. Prefer this over simple averages when observations have unequal significance (e.g. by volume, recency, or session length). Not suitable for live market scanning or safety/risk scoring.

## Known failure modes

- Fewer than 2 rows or weights provided — minimum cardinality not met
- sell_count of 0 in any row — exclusiveMinimum constraint violated
- Mismatched length between rows array and weights array
- buy_count or sell_count exceeds maximum bound of 1e16
- weights array contains negative values
- Payment not included or insufficient — x402 payment required

## How this service works

Token net buy-count balance — Weighted result mean: Weighted result mean for Token net buy-count balance. 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 weighted result mean report.

## Output

Returns a single weighted mean value representing the net buy-count balance across all supplied token observation rows, computed deterministically from the input data and weights. No live market scan or trade recommendation is included.
