# Treasury Supplied Balances — Secondary-Measure Weighted Mean + Date by Category Pivot

> Treasury Supplied Balances — Secondary-Measure Weighted Mean + Date by Category Pivot 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 secondary-measure weighted mean and a date-by-category pivot table for user-supplied treasury balance records (opening and closing balances), returning two analytical reports.

## 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-secondary-measure-weighted-mean-date-by-8f82007e -d '<json body>'
```

Example prompt: Can you run a weighted mean and date-by-category pivot on my treasury balance data? I have records with opening and closing balances across instrument groups like 'bonds' and 'equities' — use opening_balance as the field, and here are up to 200 rows in the standard format.

## When to prefer this

Choose this endpoint when you have structured treasury balance records with instrument group categorization and need both a weighted mean summary and a date-by-category pivot in a single low-cost call. It is ideal for offline/batch analytical reporting on supplied data where no live market data, external lookups, or predictions are needed. At $0.01 USDC for two reports on up to 200 rows, it is cost-effective for routine treasury analytics pipelines.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, instrument_group, date, opening_balance, closing_balance) cause validation failure
- Date field does not match YYYY-MM-DD pattern — schema validation error
- Balance values outside ±1,000,000,000,000 range rejected
- Empty rows array (minItems:1 not met) causes error
- Invalid field enum value (must be opening_balance or closing_balance)

## How this service works

Treasury supplied balances — Secondary-measure weighted mean + Date by category pivot: Secondary-measure weighted mean + Date by category pivot 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) a secondary-measure weighted mean of the selected balance field (opening_balance or closing_balance) across the supplied rows, and (2) a date-by-category pivot table breaking down balance values by date and instrument_group. Results cover up to 200 input rows and are computed locally without external data lookups.
