# Payment Reconciliation — Duplicate Key Report + Weighted Mean

> Payment Reconciliation — Duplicate Key Report + 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 2026-11-02).

Analyzes supplied payment reconciliation rows to produce a duplicate key report and a secondary-measure weighted mean, using local analytical engines on up to 200 rows.

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 payment-reconciliation-duplicate-key-report-weighted-mean-af6cf362 -d '<json body>'
```

Example prompt: I have 50 payment reconciliation records with row IDs, instrument groups, dates, expected amounts, and received amounts — can you run a duplicate key report and compute the weighted mean of expected_amount across all of them?

## When to prefer this

Choose this endpoint when you need offline, local analytical computation on payment reconciliation data specifically requiring both a duplicate key detection report and a weighted mean of a numeric measure, without sending data to a live external lookup or prediction service. It is suitable for batch quality audits of up to 200 rows at low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — exceeds maximum row limit
- Missing required fields (row_id, instrument_group, date, expected_amount, received_amount) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema rejection
- All values null for the selected measure field — weighted mean undefined
- Malformed JSON body — request parsing error

## How this service works

Payment reconciliation — Duplicate key report + Secondary-measure weighted mean: Duplicate key report + Secondary-measure weighted mean for supplied payment reconciliation records (expected_amount, received_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 duplicate key report identifying any repeated row_id or key combinations within the submitted rows, and (2) a weighted mean calculation for the selected secondary measure (expected_amount or received_amount) across the supplied records. Both reports are computed locally without external lookup or prediction.
