## 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-exact-row-deduplication-two-measure-correlation-53085877 -d '<json body>'
```

Example prompt: Can you deduplicate my savings ledger rows and run a correlation analysis between deposit and withdrawal amounts? I have about 150 rows with fields like row_id, instrument_group, date, deposit_amount, and withdrawal_amount — I need both the deduplication report and the correlation report back.

## When to prefer this

Choose this endpoint when you have a local savings ledger dataset (up to 200 rows) and need both exact row deduplication and a correlation analysis between deposit and withdrawal amounts in a single low-cost call. It is ideal for offline or batch data quality workflows where no live data lookup, prediction, or external API action is needed. Prefer alternatives if you need more than two analytical reports, more than 200 rows, real-time data, or domain types other than savings ledger data.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, date, deposit_amount, withdrawal_amount, instrument_group) — validation error
- Date field does not match YYYY-MM-DD format — schema validation failure
- Numeric values outside ±1,000,000,000,000 range — rejected
- Empty row array submitted — error returned

## How this service works

Savings ledger — Exact row deduplication + Two-measure correlation: Exact row deduplication + Two-measure correlation 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 analytical reports: (1) an exact row deduplication report identifying and removing fully duplicate rows from the submitted savings ledger records, and (2) a two-measure correlation report quantifying the statistical relationship between deposit_amount and withdrawal_amount across the supplied rows. No live data, external lookups, or predictions are included.
