# Water Service Coverage — String Normalisation + Numeric Distribution

> Water Service Coverage — String Normalisation + Numeric Distribution 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).

Performs string normalisation on region labels and computes numeric distribution statistics for water service coverage data (served_households and 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-string-normalisation-numeric-distribution-8db52cd0 -d '<json body>'
```

Example prompt: I have water service coverage records with served_households and total_households for various regions — can you run string normalisation on the region names and give me a numeric distribution report for the served_households field across my 50 rows?

## When to prefer this

Choose this endpoint when you need both string normalisation of region labels and numeric distribution analytics on household coverage figures in a single low-cost call ($0.01 USDC). It is ideal for offline batch analysis of water service datasets up to 200 rows where no live data lookup, prediction, or external action is required. Prefer alternatives if you need real-time data enrichment, geospatial lookups, or more than 200 rows processed at once.

## Known failure modes

- Rows exceeding 200 items will be rejected (maxItems constraint)
- Missing required fields (row_id, region, date, served_households, total_households) cause validation errors
- Dates not matching YYYY-MM-DD pattern will fail schema validation
- Null numeric values are accepted but may affect distribution calculations
- Invalid field enum value (not served_households or total_households) causes rejection

## How this service works

Water service coverage — String normalisation + Numeric distribution: String normalisation + Numeric distribution 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 submitted rows: (1) a string normalisation report cleaning and standardising the region label field, and (2) a numeric distribution report for the selected field (served_households or total_households), including distributional statistics such as min, max, mean, and spread metrics. Results are derived entirely from the supplied data with no external lookups.
