# Savings Ledger — Grouped Numeric Summary + Base-100 Series

> Savings Ledger — Grouped Numeric Summary + 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 2026-10-30).

Generates two analytical reports from savings ledger rows: a grouped numeric summary and a Base-100 indexed series for deposit or withdrawal amounts.

## 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 savings-ledger-grouped-numeric-summary-base-100-series-3a450d45 -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and a Base-100 series on my savings ledger? I have rows with instrument groups like 'checking' and 'high-yield', dates, deposit amounts, and withdrawal amounts — use deposit_amount as the field and start the index at row 0.

## When to prefer this

Choose this endpoint when you have tabular savings ledger data (deposits and withdrawals by group and date) and need both a grouped statistical summary and a Base-100 indexed series in a single call for under $0.01 USDC. Prefer it over general-purpose analytics tools when the data is already structured with instrument_group and date fields and you want two reports at once without external data dependencies.

## Known failure modes

- Rows array is empty or missing — minimum 1 row required
- More than 200 rows submitted — maxItems constraint violated
- Invalid date format (must be YYYY-MM-DD pattern)
- base_index out of range — must be between 0 and 199 and within actual row count
- Field value not in enum ['deposit_amount','withdrawal_amount'] — validation error
- Null numeric values may affect aggregation output depending on engine handling
- row_id missing or empty string — required field per schema

## How this service works

Savings ledger — Grouped numeric summary + Base-100 series: Grouped numeric summary + Base-100 series for supplied savings ledger records (deposit_amount, withdrawal_amount). 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 independent analytical reports: (1) a grouped numeric summary aggregating deposit_amount or withdrawal_amount statistics by instrument_group, and (2) a Base-100 time series indexing the selected field relative to the specified base row — all computed locally from the supplied data with no external lookups.
