# Elevation Samples — Numeric Row Ordering + Daily Sum Series

> Elevation Samples — Numeric Row Ordering + Daily Sum Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes numeric row ordering and daily sum series reports for up to 200 supplied elevation sample records containing elevation_m 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 elevation-samples-numeric-row-ordering-daily-sum-series-595ce3b6 -d '<json body>'
```

Example prompt: I have 4 elevation sample readings — row-1 on 2026-10-01 at 10m with weight 1 (group-a), row-2 on 2026-10-02 at 20m with weight 2 (group-b), row-3 on 2026-10-03 at 15m with weight 3 (group-a), row-4 on 2026-10-04 at 30m with weight 4 (group-b) — can you rank them numerically by row order and give me a daily sum series for elevation_m?

## When to prefer this

Choose this endpoint when you have tabular elevation sample data (up to 200 rows) and need both a numeric row-ordering report and a daily sum time series in a single $0.01 call, without requiring any external data lookups, live sensor feeds, or predictive modeling.

## Known failure modes

- More than 200 rows submitted — request will be rejected
- Missing required fields (row_id, station_group, date, elevation_m, sample_weight) on any row
- Invalid date format (must match YYYY-MM-DD pattern)
- Null or non-numeric values in elevation_m or sample_weight when not allowed
- Payment of 0.01 USDC not provided or failed via x402 protocol

## How this service works

Elevation samples — Numeric row ordering + Daily sum series: Numeric row ordering + Daily sum 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 rows: (1) a numeric row ordering that ranks the input records, and (2) a daily sum series aggregating either elevation_m or sample_weight values by date. Both reports are computed locally with no external lookups.
