# Research Sample Recovery – Numeric Row Ordering

> Research Sample Recovery – Numeric Row Ordering is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Sorts up to 200 research sample recovery records by a chosen numeric field (input_mass_g or recovered_mass_g) and returns a local descriptive analytics report.

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 research-sample-recovery-numeric-row-ordering-44abfc28 -d '<json body>'
```

Example prompt: Sort these 4 sample recovery records by recovered_mass_g and give me a numeric row ordering report: row-1 (group-a, 2026-10-01, input 10g, recovered 1g), row-2 (group-b, 2026-10-02, input 20g, recovered 2g), row-3 (group-a, 2026-10-03, input 15g, recovered 3g), row-4 (group-b, 2026-10-04, input 30g, recovered 4g).

## When to prefer this

Choose this endpoint when you have up to 200 research sample recovery records and need a simple numeric sort by input or recovered mass with local descriptive analytics, without requiring any data enrichment, forecasting, or external lookups. Ideal for laboratory data pipelines where cost ($0.01 per call) and deterministic local analytics matter more than advanced statistical modeling.

## Known failure modes

- Submitting more than 200 rows returns a validation error
- Missing required fields (row_id, specimen, date, input_mass_g, recovered_mass_g) causes rejection
- Invalid date format (not YYYY-MM-DD) fails schema validation
- Unsupported field enum value other than input_mass_g or recovered_mass_g is rejected
- Empty rows array returns an error (minimum 1 item required)

## How this service works

Research sample recovery - Numeric row ordering: Numeric row ordering for Research sample recovery. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded numeric row ordering report.

## Output

A bounded numeric row ordering report containing the submitted sample recovery records sorted by the specified mass field (input_mass_g or recovered_mass_g), along with local descriptive analytics — no external enrichment or forecasting is performed.
