## 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 software-quality-missing-value-fill-85b3a4a9 -d '<json body>'
```

Example prompt: I have up to 200 rows of software component issue tracking data with some null issues_opened values — can you fill those missing values using median imputation across the dataset?

## When to prefer this

Choose this endpoint when you have software quality issue tracking data (issues opened/closed per component per date) with missing numeric values and need a fast, cheap ($0.01 USDC), local imputation using zero, mean, or median — no external enrichment needed. Prefer this over general-purpose data cleaning tools when your records conform to the component/date/issues schema and you want a deterministic, bounded operation on up to 200 rows.

## Known failure modes

- Input array is empty or exceeds 200 items — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Unrecognized field or method enum value — rejected request
- All values in the target field are null — mean/median may be undefined or zero
- Payment not included or insufficient USDC — 402 payment required response

## How this service works

Software quality - Explicit missing-value fill: Explicit missing-value fill for Software quality. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded explicit missing-value fill deliverable.

## Output

Returns the input records with previously null or missing values in the specified field (issues_opened or issues_closed) replaced by the chosen fill value (zero, mean of non-null values, or median of non-null values). Up to 200 records are processed locally with no external enrichment.
