# Research Samples Exact Row Deduplication and Base-100 Series

> Research Samples Exact Row Deduplication and Base-100 Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Performs exact row deduplication and Base-100 index series computation on up to 200 research sample records with sample_value and 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-exact-row-deduplication-and-base-100-series-4b1d328c -d '<json body>'
```

Example prompt: Can you deduplicate these 50 research sample rows and compute a Base-100 index series on the sample_value field, using row index 0 as the base? I need both the deduplication report and the indexed series.

## When to prefer this

Choose this endpoint when you need both exact duplicate row removal and Base-100 index normalization in a single call on small-to-medium research sample datasets (up to 200 rows) with sample_value and sample_weight fields. Ideal for education research, course group analysis, or any tabular dataset requiring data cleaning and baseline indexing without external data enrichment or live lookups.

## Known failure modes

- Exceeds 200 row limit — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- base_index out of range (>=number of rows) — error
- Missing required fields row_id or sample_value — schema validation failure
- All rows are duplicates leaving empty deduplicated set — may produce empty series
- Null sample values at base_index row — Base-100 computation undefined

## How this service works

Research samples — Exact row deduplication + Base-100 series: Exact row deduplication + Base-100 series 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 analytical reports: (1) an exact row deduplication report showing which rows were duplicates and the cleaned row set, and (2) a Base-100 index series for the selected field (sample_value or sample_weight), anchored at the specified base_index row. Both reports are generated locally without external lookups.
