## 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 study-recruitment-duplicate-key-report-date-by-category-pivot-80d14a86 -d '<json body>'
```

Example prompt: I have a list of study recruitment records with row IDs, course groups, dates, and counts of eligible and enrolled candidates — can you run a duplicate key check and also give me a pivot of eligible_candidates by date and course group? Here are up to 200 rows.

## When to prefer this

Choose this endpoint when you need both a duplicate key integrity check and a date-by-category pivot on study recruitment data in a single low-cost call. It is ideal for offline/batch analytical work on supplied datasets (no live data lookup), particularly for education or clinical trial recruitment records with course_group and date dimensions, and when cost efficiency ($0.01 for two reports) matters.

## Known failure modes

- Missing required fields (row_id, date, course_group, eligible_candidates, enrolled_candidates) cause validation errors
- Date values not matching YYYY-MM-DD pattern are rejected
- More than 200 rows submitted exceeds the maxItems limit
- Empty rows array returns an error
- Invalid field enum value (not eligible_candidates or enrolled_candidates) causes rejection
- Non-numeric values for candidate count fields may fail schema validation

## How this service works

Study recruitment — Duplicate key report + Date by category pivot: Duplicate key report + Date by category pivot for supplied study recruitment records (eligible_candidates, enrolled_candidates). 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 two independent analytical reports: (1) a duplicate key report identifying any repeated row_id values within the supplied dataset, and (2) a date-by-category pivot table cross-tabulating the selected numeric field (eligible_candidates or enrolled_candidates) by date and course_group, covering up to 200 input rows.
