# Treasury Supplied Balances — Base-100 Series + Explicit Missing-Value Fill

> Treasury Supplied Balances — Base-100 Series + Explicit Missing-Value Fill 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).

Transforms up to 200 rows of treasury balance records into a base-100 indexed time series and fills any missing opening/closing balance values using zero, mean, or median imputation.

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-base-100-series-explicit-missing-value-fill-517bb889 -d '<json body>'
```

Example prompt: I have 50 rows of treasury balance data with some missing closing_balance values — can you index them to base-100 starting from row 0 and fill the missing values using median imputation?

## When to prefer this

Choose this endpoint when you need to simultaneously normalize treasury balance time series to a common base-100 index AND impute missing values in a single API call at low cost ($0.01 USDC for both reports). It is ideal for financial analysts working with instrument-grouped balance data that has data quality gaps, and when no live market lookup or external data enrichment is needed — only local analytical computation on your supplied rows.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- base_index references a row index beyond the array length
- All values for the selected field are null — mean/median imputation cannot compute a reference value
- Invalid date format (non-YYYY-MM-DD) causes row rejection
- Numeric values outside ±1,000,000,000,000 range are rejected by schema validation
- Missing required fields (row_id, instrument_group, date) cause row-level errors

## How this service works

Treasury supplied balances — Base-100 series + Explicit missing-value fill: Base-100 series + Explicit missing-value fill 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 for the selected balance field (opening_balance or closing_balance) anchored to the specified base_index row, and (2) the same dataset with missing/null balance values explicitly filled using the chosen method (zero, mean, or median). Results cover up to 200 input rows and are computed locally without external lookups.
