# Elevation Samples — Numeric Interval Filter + Base-100 Series

> Elevation Samples — Numeric Interval Filter + 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 2026-11-05).

Applies a numeric interval filter and generates a Base-100 index series for up to 200 supplied elevation sample records containing elevation_m and sample_weight fields.

## 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-numeric-interval-filter-base-100-series-cf848650 -d '<json body>'
```

Example prompt: Take my elevation sample records — rows with station_group 'alpha', dates from 2025-01-01 to 2025-01-04, elevation_m values of 50, 75, 120, and 200, and sample_weight values of 1, 2, 3, and 4 — filter on the elevation_m field between 0 and 150, and generate a Base-100 index series using row index 0 as the base.

## When to prefer this

Choose this endpoint when you have pre-collected elevation sample records (with elevation_m and sample_weight) and need two offline analytical outputs — a numeric range filter and a Base-100 index series — without requiring any live data lookup, external API call, or geospatial computation. Ideal for batch post-processing of up to 200 rows of station measurement data at low cost ($0.01 USDC for both reports).

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, date, elevation_m, sample_weight, station_group) — validation error
- base_index out of bounds for provided row count — error or fallback
- minimum greater than maximum — interval filter returns empty set
- Non-conforming date format (not YYYY-MM-DD) — validation rejection
- null values in elevation_m or sample_weight may affect index calculation

## How this service works

Elevation samples — Numeric interval filter + Base-100 series: Numeric interval filter + 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 analytical reports for the supplied elevation sample dataset: (1) a numeric interval filter report identifying records where the selected field (elevation_m or sample_weight) falls within the specified minimum–maximum range, and (2) a Base-100 index series normalizing the selected field values relative to the specified base row. Up to 200 rows processed per call.
