# Glossary Coverage Analyzer — Category Frequencies + Numeric Interval Filter

> Glossary Coverage Analyzer — Category Frequencies + Numeric Interval Filter is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Computes category frequency counts and applies a numeric interval filter on glossary coverage records (covered_terms, required_terms) for up to 200 rows, returning two analytical reports.

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 glossary-coverage-analyzer-category-frequencies-numeric-interval-filter-98d8f7b1 -d '<json body>'
```

Example prompt: Can you analyze my glossary coverage records — I have 4 rows with document groups 'group-a' and 'group-b', covered_terms ranging from 10 to 30, and required_terms from 1 to 4 — give me the category frequencies by document_group and filter covered_terms between 10 and 25?

## When to prefer this

Choose this endpoint when you need two complementary analytical views on glossary coverage data in a single low-cost call: a categorical frequency breakdown by document group and a numeric range filter on term counts. It is ideal for auditing terminology completeness across document groups without any external data dependencies. Prefer it over general-purpose analytics tools when working specifically with covered_terms/required_terms structures and needing a fast, cheap ($0.01) batch report on up to 200 records.

## Known failure modes

- More than 200 rows submitted — request exceeds maxItems limit
- Missing required fields (row_id, document_group, date, covered_terms, required_terms) in any row
- Date field not matching YYYY-MM-DD pattern
- Minimum value greater than maximum value causing empty filter result
- Numeric values outside the allowed range (-1,000,000,000,000 to 1,000,000,000,000)
- Invalid field enum value (must be 'covered_terms' or 'required_terms')
- Payment not included or insufficient — requires 0.01 USDC via x402

## How this service works

Glossary coverage — Category frequencies + Numeric interval filter: Category frequencies + Numeric interval filter for supplied glossary coverage records (covered_terms, required_terms). 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 category frequency table showing counts per document_group value, and (2) a filtered subset of rows where the selected numeric field (covered_terms or required_terms) falls within the specified minimum–maximum interval. Both reports are computed locally from the supplied data with no external lookups.
