# Brand Mention Inventories — Numeric Interval Filter + Base-100 Series

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

Filters brand mention inventory rows by a numeric range and computes a Base-100 index series for mention_count or source_count, delivering two analytical reports for up to 200 supplied rows.

## 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-interval-filter-base-100-series-1469c821 -d '<json body>'
```

Example prompt: I have brand mention inventory data for two company groups across October 2026 — can you filter it to rows where mention_count is between 10 and 25, and then build a Base-100 index series using the first row as the base, for the mention_count field?

## When to prefer this

Choose this endpoint when you have pre-collected brand mention inventory data (mention_count, source_count) that you want to (a) restrict to a meaningful numeric range and (b) normalize into a Base-100 trend series — all in a single cheap call ($0.01 USDC). It is purely analytical on supplied data with no external lookups, making it deterministic and fast. Prefer it over general-purpose data tools when you specifically need both interval filtering and base-indexing on brand mention metrics together.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maxItems limit
- base_index references a row index out of range of the supplied array
- Field value contains nulls at the base_index row — division by zero in indexing
- Date strings not matching YYYY-MM-DD pattern — schema validation error
- minimum greater than maximum — may return empty filtered set with no error

## How this service works

Brand mention inventories — Numeric interval filter + Base-100 series: Numeric interval filter + Base-100 series 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) the subset of input rows whose selected numeric field (mention_count or source_count) falls within the specified [minimum, maximum] interval, and (2) a Base-100 index series for that field anchored at the specified base_index row, allowing relative trend comparison across up to 200 brand mention inventory records.
