# Staking Supplied Rewards — Duplicate Key Report + Secondary-Measure Weighted Mean

> Staking Supplied Rewards — Duplicate Key Report + Secondary-Measure Weighted Mean 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).

Analyzes up to 200 staking reward records by detecting duplicate row keys and computing a secondary-measure weighted mean across reward_units or staked_units fields.

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 staking-supplied-rewards-duplicate-key-report-secondary-measure-624a84bb -d '<json body>'
```

Example prompt: Check my staking rewards data for duplicate row IDs and compute the weighted mean for reward_units — I have 4 rows: row-1 on 2026-10-01 with reward_units=10 and staked_units=1 in group-a, row-2 on 2026-10-02 with reward_units=20 and staked_units=2 in group-b, row-3 on 2026-10-03 with reward_units=15 and staked_units=3 in group-a, and row-4 on 2026-10-04 with reward_units=30 and staked_units=4 in group-b.

## When to prefer this

Choose this endpoint when you need to simultaneously audit staking reward records for duplicate row keys AND compute a weighted mean statistic on reward_units or staked_units in a single low-cost call ($0.01 USDC for both reports). It is ideal for batch data quality workflows on datasets up to 200 rows where no live blockchain lookup or external data enrichment is needed — purely local analytical computation on supplied data.

## Known failure modes

- Input exceeds 200 rows — request rejected with validation error
- Missing required fields (row_id, date, instrument_group) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Numeric values outside ±1,000,000,000,000 range — rejected
- Empty rows array — minItems constraint violation
- Payment failure — x402 protocol micropayment not processed

## How this service works

Staking supplied rewards — Duplicate key report + Secondary-measure weighted mean: Duplicate key report + Secondary-measure weighted mean 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 two independent analytical reports: (1) a duplicate key report identifying any row_ids that appear more than once in the submitted records, and (2) a secondary-measure weighted mean computed for the selected field (reward_units or staked_units) weighted against the other measure, across up to 200 input rows.
