# Elevation Samples — Duplicate Key Report + Base-100 Series

> Elevation Samples — Duplicate Key Report + 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 2026-10-31).

Analyzes up to 200 elevation sample records to produce a duplicate key report and a base-100 indexed series for a chosen numeric field.

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 elevation-samples-duplicate-key-report-base-100-series-5e5eec29 -d '<json body>'
```

Example prompt: I have 150 elevation sample rows with fields row_id, station_group, date, elevation_m, and sample_weight — can you run a duplicate key report and also produce a base-100 series on elevation_m starting from row index 0?

## When to prefer this

Choose this endpoint when you have tabular elevation or geospatial sample data and need both a duplicate key audit and a base-100 normalized series in a single low-cost call. It is ideal for data quality checks on survey or sensor datasets where key uniqueness and relative indexing are both required. It does not perform live lookups, predictions, or external data fetching — use it strictly for local analytical computation on your own supplied rows.

## Known failure modes

- Fewer than 1 row supplied — validation error
- More than 200 rows supplied — rejected with max-items error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- base_index out of range (≥ number of rows) — index error
- Non-numeric values in elevation_m or sample_weight fields — type error
- Missing required fields (row_id, station_group, date) — schema rejection

## How this service works

Elevation samples — Duplicate key report + Base-100 series: Duplicate key report + Base-100 series for supplied elevation samples records (elevation_m, 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 identifying which row_id values appear more than once in the supplied dataset, and (2) a base-100 series rebasing the chosen numeric field (elevation_m or sample_weight) relative to the row at the specified base_index, covering up to 200 rows of input data.
