# Brand Mention Inventories — Numeric Row Ordering + Keyed Dataset Comparison

> Brand Mention Inventories — Numeric Row Ordering + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Ranks brand mention inventory rows numerically and compares two brand mention datasets by key, covering mention_count and source_count fields for up to 200 rows per report.

## 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 brand-mention-inventories-numeric-row-ordering-keyed-dataset-comparison-5cc19b61 -d '<json body>'
```

Example prompt: I have two sets of brand mention data — both with up to 50 rows each containing row_id, company_group, date, mention_count, and source_count — can you rank each dataset's rows numerically by mention_count and also compare the two datasets side by side by row_id?

## When to prefer this

Choose this endpoint when you have pre-collected brand mention inventory data (with mention_count and source_count fields) and need both a numeric row ranking and a keyed side-by-side comparison of two datasets in a single $0.01 call — particularly when no live data lookup, real-time scraping, or external enrichment is needed and you want purely local, deterministic analytical computation on up to 200 rows.

## Known failure modes

- Input array is empty or missing required fields (row_id, company_group, date, mention_count, source_count) — returns validation error
- More than 200 rows submitted — request rejected with row limit error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Numeric field values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — rejected
- Missing 'other' comparison dataset when comparison report is needed — may return incomplete results
- Invalid field enum value (not mention_count or source_count) — schema error

## How this service works

Brand mention inventories — Numeric row ordering + Keyed dataset comparison: Numeric row ordering + Keyed dataset comparison for supplied brand mention inventories records (mention_count, source_count). 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 numerically ordered ranking of the input rows by the selected field (mention_count or source_count), and (2) a keyed comparison between the primary and secondary dataset rows, highlighting differences per row_id — all computed locally with no external lookups.
