# Water Service Coverage Analyzer — Category Frequencies & Numeric Interval Filter

> Water Service 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 2026-10-30).

Analyzes supplied water service coverage data by computing category frequencies for regions and filtering records by a numeric interval on household fields, returning two analytical reports for up to 200 rows.

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 water-service-coverage-analyzer-category-frequencies-numeric-interval-f4a9bf76 -d '<json body>'
```

Example prompt: I have water service coverage records with region, date, served_households, and total_households columns — can you run a category frequency breakdown by region and also filter to only records where served_households is between 10 and 500, using up to 200 rows of my data?

## When to prefer this

Choose this endpoint when you have pre-collected water service coverage tabular data (up to 200 rows) and need both a regional category frequency summary and a numeric range filter on household counts in a single API call. It is ideal for offline/batch analytical passes on your own dataset without needing a live data source, prediction, or external lookup. Prefer this over general-purpose analytics tools when working within the x402 micropayment ecosystem and needing two bundled reports cheaply ($0.01 USDC).

## Known failure modes

- Fewer than 1 row submitted — rejected by minItems constraint
- More than 200 rows submitted — truncated or rejected by maxItems constraint
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in served_households or total_households may affect interval filtering results
- Field enum value not matching 'served_households' or 'total_households' — validation error
- Minimum value greater than maximum value — may return empty interval filter result

## How this service works

Water service coverage — Category frequencies + Numeric interval filter: Category frequencies + Numeric interval filter for supplied water service coverage records (served_households, total_households). 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 how often each unique region value appears across the submitted rows, and (2) a filtered subset of records where the selected numeric field (served_households or total_households) falls within the specified minimum–maximum interval. Both reports are computed locally without external lookups.
