# Trade Observations — Numeric Row Ordering + Trailing Mean Series

> Trade Observations — Numeric Row Ordering + Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Computes numeric row ordering ranks and trailing moving-average series for trade observation records (export_amount, import_amount) over up to 200 rows.

## 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 trade-observations-numeric-row-ordering-trailing-mean-series-2f33dbc6 -d '<json body>'
```

Example prompt: Can you rank my trade observation rows and compute a trailing mean series with a window of 3 for the export_amount field? I have 4 records: row-1 (2026-10-01, group-a, export 10, import 1), row-2 (2026-10-02, group-b, export 20, import 2), row-3 (2026-10-03, group-a, export 15, import 3), row-4 (2026-10-04, group-b, export 30, import 4).

## When to prefer this

Choose this endpoint when you need both numeric row ranking and a trailing moving-average series computed together on trade economics data (export/import amounts) in a single low-cost call. It is ideal for offline/batch analytics on supplied datasets up to 200 rows where no live data lookup or prediction is needed. Prefer it over general statistics APIs when you specifically need these two complementary reports on trade observation records at a fixed $0.01 USDC price.

## Known failure modes

- Fewer than 1 row supplied — rejected by minItems constraint
- More than 200 rows supplied — rejected by maxItems constraint
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Missing required fields (row_id, region, date, export_amount, import_amount) — validation failure
- Window size outside 2–200 range — schema rejection
- Invalid field enum value (not export_amount or import_amount) — schema rejection
- Payment not attached or insufficient — 402 Payment Required

## How this service works

Trade observations — Numeric row ordering + Trailing mean series: Numeric row ordering + Trailing mean series for supplied trade observations records (export_amount, import_amount). 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 independent analytical reports for the supplied trade records: (1) a numeric row ordering report assigning sequential rank positions to each row, and (2) a trailing mean series report computing rolling averages over the chosen window for the specified field (export_amount or import_amount). Both reports use local analytical engines with no external lookups.
