# Research Samples — Duplicate Key Report + Numeric Interval Filter

> Research Samples — 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 2026-10-23).

Analyzes up to 200 research sample rows to produce a duplicate key report and a numeric interval filter report for sample_value or sample_weight fields.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 research-samples-duplicate-key-report-numeric-interval-filter-96ee9c64 -d '<json body>'
```

Example prompt: Check my research sample dataset for duplicate row IDs and also filter sample_value between 10 and 150 — I have about 80 rows with row_id, course_group, date, sample_value, and sample_weight fields.

## When to prefer this

Choose this endpoint when you need both duplicate key detection and numeric range filtering on research sample data in a single low-cost call. It is ideal for data quality checks on small-to-medium datasets (up to 200 rows) with sample_value and sample_weight fields. It does not perform live lookups, predictions, or external enrichment — use it purely for local analytical reporting on data you supply directly.

## Known failure modes

- Exceeding 200 rows will cause rejection — keep input within maxItems limit
- Invalid date format (not YYYY-MM-DD) will fail schema validation
- Missing required fields (row_id, course_group, date, sample_value, sample_weight) will cause request rejection
- Minimum greater than maximum in interval filter may return empty result set
- Payment failure via x402 protocol will block execution

## How this service works

Research samples — Duplicate key report + Numeric interval filter: Duplicate key report + Numeric interval filter for supplied research samples records (sample_value, sample_weight). 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 listing any row_ids that appear more than once in the input, and (2) a numeric interval filter report showing which rows have the specified field (sample_value or sample_weight) within the given minimum–maximum range. Results are computed locally from the supplied data with no external lookups.
