# Treasury Supplied Balances — Base-100 Series + Two-Measure Correlation

> Treasury Supplied Balances — Base-100 Series + Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Computes a Base-100 indexed series and a two-measure correlation report for supplied treasury opening and closing balance data, returning two analytical reports for 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-base-100-series-two-measure-correlation-ab71809b -d '<json body>'
```

Example prompt: I have treasury balance records for Q4 with opening and closing balances across several instrument groups — can you run a Base-100 series (starting from row index 0) on the closing_balance field, plus a two-measure correlation report, across all 12 rows?

## When to prefer this

Choose this endpoint when you already have treasury balance data (opening and closing balances by date and instrument group) and need two standard financial analytics — a Base-100 indexed series for trend visualization and a correlation coefficient between the two balance measures — in a single low-cost API call. It is ideal for batch offline analytics on supplied data (up to 200 rows) rather than live market data retrieval or prediction tasks.

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows submitted exceeds the maxItems limit
- base_index pointing to a row with a null or zero balance may cause division errors in indexing
- Invalid date format (not YYYY-MM-DD) fails schema validation
- opening_balance or closing_balance values outside ±1,000,000,000,000 are rejected
- Null values in both balance fields for a row may degrade correlation quality

## How this service works

Treasury supplied balances — Base-100 series + Two-measure correlation: Base-100 series + Two-measure correlation 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 Base-100 indexed series showing each row's selected balance field (opening_balance or closing_balance) normalized relative to the chosen base index row, and (2) a two-measure correlation report quantifying the statistical relationship between opening_balance and closing_balance across the supplied rows. Up to 200 rows supported; all computation is performed locally on supplied data with no external lookups.
