## 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 staking-supplied-rewards-string-normalisation-grouped-numeric-summary-4354ceb3 -d '<json body>'
```

Example prompt: Can you clean up the instrument group strings and give me a grouped numeric summary for reward_units across these staking records — I have 4 rows: row-1 on 2026-10-01 group-a with reward_units 10 and staked_units 1, row-2 on 2026-10-02 group-b reward_units 20 staked_units 2, row-3 on 2026-10-03 group-a reward_units 15 staked_units 3, row-4 on 2026-10-04 group-b reward_units 30 staked_units 4?

## When to prefer this

Choose this endpoint when you have up to 200 staking reward records with reward_units and staked_units and need both string normalisation and a grouped numeric summary in a single low-cost call ($0.01 USDC). It is ideal for offline/batch analytical processing of supplied data without requiring live blockchain lookups or external data sources. Prefer it over general-purpose analytics tools when you want a bundled 2-report output specifically shaped for staking instrument data.

## Known failure modes

- Exceeds 200-row limit — request rejected with validation error
- Missing required fields (row_id, instrument_group, date, reward_units, staked_units) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Numeric values outside allowed range (-1e12 to 1e12) — validation failure
- Empty rows array — minItems constraint violation
- Invalid field enum value — must be reward_units or staked_units

## How this service works

Staking supplied rewards — String normalisation + Grouped numeric summary: String normalisation + Grouped numeric summary for supplied staking supplied rewards records (reward_units, staked_units). 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 2 independent analytical reports: (1) a string-normalised version of the supplied staking records with cleaned instrument_group and date fields, and (2) a grouped numeric summary of the selected field (reward_units or staked_units) aggregated by instrument_group, covering statistics such as counts, sums, and averages per group.
