# Brand Mention Inventories — Base-100 Series + Equal-Width Histogram

> Brand Mention Inventories — Base-100 Series + 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).

Computes a Base-100 indexed time series and an equal-width histogram for brand mention inventory data (mention_count or source_count) supplied by the caller, using local analytical engines with no external lookups.

## 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-base-100-series-equal-width-histogram-4e3518c6 -d '<json body>'
```

Example prompt: Take my brand mention data for groups 'acme' and 'globex' from January 2025 — mention_count and source_count per day — and give me both a Base-100 series indexed to row 0 and an equal-width histogram with 10 bins on mention_count.

## When to prefer this

Choose this endpoint when you have pre-collected brand mention inventory data (mention_count, source_count) and need both a normalized Base-100 time series and a histogram distribution report in a single call. It is ideal for offline or batch analytical workflows where data is already aggregated and no live data fetching, prediction, or external enrichment is needed. Prefer it over generic analytics tools when you need both reports together at low cost ($0.01 USDC for up to 200 rows).

## Known failure modes

- Row count exceeds 200 items — request rejected
- base_index out of range for provided rows
- Invalid date format (must be YYYY-MM-DD)
- Field value is null for the base_index row, making indexing undefined
- bins parameter outside 1–30 range
- Missing required row fields (row_id, company_group, date, mention_count, source_count)
- Payment failure or insufficient USDC balance

## How this service works

Brand mention inventories — Base-100 series + Equal-width histogram: Base-100 series + Equal-width histogram 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 analytical reports: (1) a Base-100 indexed series where each row's selected field value is normalized relative to the chosen base row, and (2) an equal-width histogram showing frequency distribution of the selected field across the specified number of bins — both computed locally from the supplied brand mention inventory rows.
