## 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-category-frequencies-9474e6be -d '<json body>'
```

Example prompt: I have a batch of software issue records with component names like 'auth-service' and 'payment-gateway' — can you count how frequently each component category appears across my up to 200 rows of issue data?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC) local frequency count of component categories from a small batch of software issue records (up to 200 rows) without needing external enrichment, forecasting, or time-series analysis. It is ideal for lightweight quality dashboards, sprint retrospectives, or audit summaries where only categorical distribution of the component field is needed.

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows submitted exceeds the batch limit
- Missing required fields (row_id, component, date, issues_opened, issues_closed) cause validation failure
- Malformed date strings not matching YYYY-MM-DD pattern are rejected
- Numeric values outside the allowed range cause schema validation errors

## How this service works

Software quality - Category frequencies: Category frequencies 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 category frequencies deliverable.

## Output

A frequency count (tally) of how often each unique component category appears across the submitted rows, delivered as a bounded categorical distribution — typically including each distinct component name and its record count within the batch of up to 200 rows.
