# Reservoir Observations — Numeric Row Ordering + Numeric Interval Filter

> Reservoir Observations — Numeric Row Ordering + 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 2026-10-29).

Sorts reservoir observation records by a numeric field and filters them to a specified numeric interval, returning up to 2 analytical reports for up to 200 supplied rows.

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 reservoir-observations-numeric-row-ordering-numeric-interval-filter-ccb860cc -d '<json body>'
```

Example prompt: I have 50 daily reservoir readings with stored_m3 and capacity_m3 values — can you sort them by stored_m3 and filter to only show rows where stored_m3 is between 5000 and 50000 cubic meters?

## When to prefer this

Choose this endpoint when you have pre-collected reservoir observation data (stored_m3, capacity_m3) and need lightweight numeric ordering and interval filtering analytics on up to 200 rows without any external data lookup, prediction, or live feed. Ideal for batch analysis of historical or snapshot reservoir datasets at very low cost ($0.01 USDC for 2 reports).

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected or truncated
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- stored_m3 or capacity_m3 outside allowed range (±1 trillion) — rejected
- minimum value greater than maximum value — may return empty interval result
- Missing required fields (row_id, station_group, date) — validation error

## How this service works

Reservoir observations — Numeric row ordering + Numeric interval filter: Numeric row ordering + Numeric interval filter for supplied reservoir observations records (stored_m3, capacity_m3). 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 up to 2 analytical reports based on the supplied reservoir rows: one providing numeric row ordering by the selected field (stored_m3 or capacity_m3), and one filtering rows to those within the specified minimum–maximum numeric interval. Results are derived entirely from the submitted data with no external lookups.
