# Water Service Coverage Analytics — Numeric Distribution + Daily Sum Series

> Water Service Coverage Analytics — Numeric Distribution + 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 2026-10-29).

Computes a numeric distribution and a daily sum time series for water service coverage data (served_households, total_households) across 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-analytics-numeric-distribution-daily-sum-series-70cee269 -d '<json body>'
```

Example prompt: I have water service coverage records for two regions — can you run a numeric distribution and a daily sum series on the served_households field? I have 4 rows: region group-a on 2026-10-01 with served=10 total=1, group-b on 2026-10-02 with served=20 total=2, group-a on 2026-10-03 with served=15 total=3, and group-b on 2026-10-04 with served=30 total=4.

## When to prefer this

Choose this endpoint when you have tabular water service coverage data (up to 200 rows) and need both a distribution summary and a daily aggregate time series in a single low-cost call ($0.01 USDC). It is ideal for offline or batch analytical workflows where no live data lookup or external prediction is needed — just deterministic statistical computation on user-supplied records.

## Known failure modes

- Missing required fields (row_id, region, date, served_households, total_households) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- Submitting more than 200 rows exceeds the maxItems limit
- Null values in the selected numeric field may affect distribution or sum calculations
- Invalid field enum value (anything other than served_households or total_households) causes rejection
- Empty rows array (minItems:1 violated) returns an error

## How this service works

Water service coverage — Numeric distribution + Daily sum series: Numeric distribution + 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 for the specified field: (1) a numeric distribution summarizing the statistical spread of values across the supplied rows, and (2) a daily sum series aggregating the field by date. Both reports are derived entirely from the user-supplied rows using local analytical engines — no external data is fetched.
