# Treasury Supplied Balances — Category Frequencies + Trailing Mean Series

> Treasury Supplied Balances — Category Frequencies + Trailing Mean Series 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 category frequencies and a trailing mean series for treasury-supplied opening or closing balance records across up to 200 rows.

## 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 treasury-supplied-balances-category-frequencies-trailing-mean-series-3b4b3ea1 -d '<json body>'
```

Example prompt: Can you run category frequency and trailing mean analysis on my treasury supplied balance records — I'll supply up to 50 rows each with a row_id, instrument_group, date, opening_balance, and closing_balance; analyze the closing_balance field with a window of 5?

## When to prefer this

Choose this endpoint when you need both a categorical frequency breakdown and a rolling mean time series for treasury balance data (opening or closing) in a single $0.01 USDC call. Ideal for batch offline analysis of up to 200 rows of treasury records without requiring any live data feeds or external lookups. Prefer this over separate analytics tools when you want two complementary reports — distribution and trend — delivered together cheaply and quickly.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected with maxItems error
- Window size larger than number of rows — may produce empty or partial trailing mean series
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Numeric values outside ±1,000,000,000,000 range — rejected
- Missing required fields (row_id, instrument_group, date, opening_balance, closing_balance) — schema error
- Payment of 0.01 USDC not included or rejected — 402 Payment Required

## How this service works

Treasury supplied balances — Category frequencies + Trailing mean series: Category frequencies + Trailing mean series for supplied treasury supplied balances records (opening_balance, closing_balance). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two analytical reports: (1) category frequency counts showing how often each instrument_group value appears in the submitted rows, and (2) a trailing mean series showing rolling averages of the selected numeric field (opening_balance or closing_balance) over the specified window size. Both reports are derived locally from the submitted data with no external lookups.
