# Patch Inventories — String Normalisation + Explicit Missing-Value Fill

> Patch Inventories — String Normalisation + Explicit Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Normalises strings and fills missing values (zero, mean, or median) in patch inventory records containing affected_hosts and patched_hosts fields, up to 200 rows across 2 reports.

## 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 patch-inventories-string-normalisation-explicit-missing-value-fill-c799c24c -d '<json body>'
```

Example prompt: Can you clean up my patch inventory data? I have 4 rows with control groups 'group-a' and 'group-b', dates from 2026-10-01 to 2026-10-04, and some null values in the affected_hosts field — please fill those missing values using the median method.

## When to prefer this

Choose this endpoint when you need lightweight, local data-quality processing for patch inventory records specifically — normalising string fields and imputing missing numeric host-count values without any external lookup or live data. It is best suited for batch pre-processing of up to 200 rows at very low cost ($0.01 USDC for 2 reports). Prefer it over general-purpose data-cleaning services when your data matches the patch inventory schema (affected_hosts, patched_hosts, control_group, date).

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- Missing required fields (row_id, control_group, date) — schema error
- Invalid fill method enum value — validation error
- Invalid field enum value — validation error
- Payment not received or insufficient — 402 response

## How this service works

Patch inventories — String normalisation + Explicit missing-value fill: String normalisation + Explicit missing-value fill for supplied patch inventories records (affected_hosts, patched_hosts). 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 up to 2 cleaned analytical reports covering the supplied patch inventory rows, with string fields normalised and missing numeric values in the specified field (affected_hosts or patched_hosts) explicitly filled using the chosen method (zero, mean, or median). Each report covers up to 200 input rows.
