# Treasury Supplied Balances — Trailing Mean Series + Base-100 Series

> Treasury Supplied Balances — Trailing Mean Series + Base-100 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 trailing moving-average series and a base-100 indexed series for treasury supplied balance records (opening or closing balance) across up to 200 rows, returning two analytical reports.

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 treasury-supplied-balances-trailing-mean-series-base-100-series-b28295eb -d '<json body>'
```

Example prompt: Run a trailing mean and base-100 index analysis on my treasury balance data — I have 12 rows of daily opening_balance figures by instrument group, use a window of 3 and set the base at row index 0.

## When to prefer this

Choose this endpoint when you have treasury-domain balance records (opening or closing) and need both a rolling/trailing mean smoothing and a base-100 normalization in a single paid API call. It is purpose-built for treasury balance time series and bundles two analytical outputs at $0.01 USDC, making it efficient when both report types are needed simultaneously without setting up local compute.

## Known failure modes

- Fewer than 1 row provided — request rejected
- window size larger than number of rows — may produce sparse or empty trailing mean output
- base_index out of range for provided rows — invalid index error
- Non-numeric or null values in the selected field — may produce null entries in output
- More than 200 rows submitted — request rejected due to maxItems constraint
- Invalid date format (not YYYY-MM-DD) — schema validation failure

## How this service works

Treasury supplied balances — Trailing mean series + Base-100 series: Trailing mean series + Base-100 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

Two analytical reports: (1) a trailing mean series showing smoothed balance values over the specified rolling window, and (2) a base-100 indexed series rebasing the selected balance field relative to the chosen base row index — both computed locally for up to 200 input rows.
