# Assignment Turnaround — Duplicate Key Report + Numeric Interval Filter

> Assignment Turnaround — Duplicate Key Report + Numeric Interval Filter is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Runs two local analytical reports on assignment turnaround data: a duplicate key detection report and a numeric interval filter, over up to 200 rows of submission/feedback records.

## 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 assignment-turnaround-duplicate-key-report-numeric-interval-filter-636b042d -d '<json body>'
```

Example prompt: Check my assignment turnaround records for duplicate row IDs and also filter to only show rows where submission_count is between 5 and 40 — here are 4 rows: row-1 group-a 2026-10-01 feedback_hours=1 submission_count=10, row-2 group-b 2026-10-02 feedback_hours=2 submission_count=20, row-3 group-a 2026-10-03 feedback_hours=3 submission_count=15, row-4 group-b 2026-10-04 feedback_hours=4 submission_count=30.

## When to prefer this

Choose this endpoint when you need both duplicate row ID detection and numeric range filtering on education/assignment turnaround data (submission counts and feedback hours) in a single low-cost call. It is ideal for data quality checks before reporting or aggregation, when you have up to 200 rows and want local analytical results without any external API calls, predictions, or live lookups.

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows submitted exceeds the limit and is rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- field enum value not matching 'submission_count' or 'feedback_hours' causes rejection
- minimum greater than maximum may return an empty interval filter result
- Null numeric values for the filtered field may be excluded or flagged
- Missing required row fields (row_id, course_group, date) causes validation errors

## How this service works

Assignment turnaround — Duplicate key report + Numeric interval filter: Duplicate key report + Numeric interval filter for supplied assignment turnaround records (submission_count, feedback_hours). 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 reports: (1) a duplicate key report identifying any row_id values that appear more than once in the supplied data, and (2) a numeric interval filter listing which rows fall within the specified minimum and maximum range for the chosen field (submission_count or feedback_hours). Both reports are computed locally on the supplied data with no external lookup.
