# Contract Renewal Inventories — Duplicate Key Report + Equal-Width Histogram

> Contract Renewal Inventories — Duplicate Key Report + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Analyzes up to 200 rows of contract renewal inventory data to produce a duplicate key report and an equal-width histogram for a chosen numeric field.

## 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 contract-renewal-inventories-duplicate-key-report-equal-width-histogram-e660645f -d '<json body>'
```

Example prompt: Check my contract renewal data for duplicate row IDs and also give me a 10-bin equal-width histogram on the expiring_contracts field — here are the rows: row-1, group-a, 2026-10-01, 10 expiring, 1 renewed; row-2, group-b, 2026-10-02, 20 expiring, 2 renewed; row-3, group-a, 2026-10-03, 15 expiring, 3 renewed.

## When to prefer this

Choose this endpoint when you need simultaneous duplicate-key detection and a numeric distribution histogram on contract renewal inventory data (expiring_contracts or renewed_contracts) in a single call, without requiring live database lookups or external integrations. It is well-suited for pre-processing data quality checks and quick statistical summaries on batches of up to 200 rows at low cost ($0.01 USDC for both reports).

## Known failure modes

- Exceeding 200 rows causes rejection
- Missing required fields (row_id, company_group, date, expiring_contracts, renewed_contracts) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema error
- bins value outside 1–30 range is rejected
- Null numeric values in the selected histogram field may produce incomplete bin coverage
- Empty rows array is rejected

## How this service works

Contract renewal inventories — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram for supplied contract renewal inventories records (expiring_contracts, renewed_contracts). 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 supplied data, and (2) an equal-width histogram for the selected numeric field (expiring_contracts or renewed_contracts) broken into the specified number of bins (1–30), showing counts per bin. No external data is fetched; all computation uses local analytical engines on the supplied rows.
