# Elevation Samples — Numeric Distribution + Numeric Interval Filter

> Elevation Samples — Numeric Distribution + 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 2026-11-02).

Computes a numeric distribution report and a numeric interval filter report for up to 200 supplied elevation sample records (elevation_m, sample_weight).

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-numeric-distribution-numeric-interval-filter-6babd100 -d '<json body>'
```

Example prompt: Analyze the distribution of elevation_m values and also filter them between 50 and 500 meters for these 4 station readings: row-1 on 2026-10-01 at group-a elevation 10m weight 1, row-2 on 2026-10-02 at group-b elevation 20m weight 2, row-3 on 2026-10-03 at group-a elevation 15m weight 3, row-4 on 2026-10-04 at group-b elevation 30m weight 4.

## When to prefer this

Choose this endpoint when you have a batch of up to 200 elevation sample records and need both a statistical distribution of a numeric field and an interval-filtered view in a single call. It is ideal for offline/local analytical computation on already-collected elevation or sample-weight data when no live data lookup, external enrichment, or prediction is needed. Prefer it over general statistics APIs when your data includes the specific elevation_m and sample_weight schema and you want two coordinated reports for one fixed low price.

## Known failure modes

- More than 200 rows submitted — request rejected due to row limit
- Missing required fields (row_id, station_group, date, elevation_m, sample_weight) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- minimum greater than maximum causes empty or invalid interval filter result
- Null values in elevation_m or sample_weight may affect distribution accuracy
- Payment of 0.01 USDC not fulfilled causes 402 response

## How this service works

Elevation samples — Numeric distribution + Numeric interval filter: Numeric distribution + Numeric interval filter 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 rows: (1) a numeric distribution report showing the statistical spread and frequency breakdown of the selected field (elevation_m or sample_weight), and (2) a numeric interval filter report listing or summarizing records where the selected field falls within the specified minimum–maximum range. Both reports are computed locally from the supplied data with no external lookups.
