## 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-record-quality-audit-grouped-numeric-summary-64baa6de -d '<json body>'
```

Example prompt: Can you run a record quality audit and grouped numeric summary on my savings ledger data? I have rows with instrument groups like 'group-a' and 'group-b', dates, deposit amounts, and withdrawal amounts — I want to audit the deposit_amount field.

## When to prefer this

Use this endpoint when you need both a data quality check and a grouped numeric summary for savings ledger data (deposits and withdrawals) in a single call, without any need for external lookups, predictions, or live data. It is cost-effective at $0.01 for two reports on up to 200 rows. Prefer this over generic analytics tools when your data is specifically structured as savings ledger records with instrument groups, dates, and monetary amounts.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, instrument_group, date, deposit_amount, withdrawal_amount) in one or more rows — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Payment not processed — endpoint returns 402
- Empty rows array — minimum 1 item required

## How this service works

Savings ledger — Record quality audit + Grouped numeric summary: Record quality audit + Grouped numeric summary 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 reports: (1) a record quality audit identifying issues such as missing values, nulls, or malformed fields across the supplied rows, and (2) a grouped numeric summary aggregating the selected field (deposit_amount or withdrawal_amount) by instrument_group, with statistics like totals, counts, and averages per group. No external data is fetched; all analysis is performed on the supplied rows only.
