# Water Service Coverage — Numeric Interval Filter + Daily Sum Series

> Water Service Coverage — Numeric Interval Filter + Daily Sum Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Filters water service coverage records by a numeric interval on a chosen field and computes daily sum time series, returning two analytical reports for up to 200 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 water-service-coverage-numeric-interval-filter-daily-sum-series-6753531f -d '<json body>'
```

Example prompt: I have 150 water service records with served_households and total_households by region and date — can you filter for rows where served_households is between 10 and 500, then give me the daily sum series for served_households?

## When to prefer this

Choose this endpoint when you have pre-collected water service coverage data (served_households, total_households) and need two simultaneous local analytical operations — numeric interval filtering and daily sum aggregation — without any live data lookup or external API calls. It is purpose-built for water/utility coverage datasets up to 200 rows and is cost-effective at $0.01 USDC for both reports together.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row rejection
- minimum greater than maximum produces empty filter results
- Missing required fields (row_id, region, date) cause validation errors
- Null values in the target numeric field are excluded from sum aggregation
- Payment of 0.01 USDC not completed causes request to fail with 402 status

## How this service works

Water service coverage — Numeric interval filter + Daily sum series: Numeric interval filter + Daily sum series 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

Two analytical reports: (1) rows from the input dataset where the selected field (served_households or total_households) falls within the specified numeric interval [minimum, maximum], and (2) a daily sum time series aggregating that field by date across all matching or input records. Results cover up to 200 input rows.
