# Trade Observations Duplicate Key Report + Base-100 Series

> Trade Observations Duplicate Key Report + Base-100 Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Runs two local analytical reports on trade observation rows: identifies duplicate row keys and computes a Base-100 indexed series for export_amount or import_amount.

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 trade-observations-duplicate-key-report-base-100-series-421acf0d -d '<json body>'
```

Example prompt: Check my trade records for duplicate row IDs and also give me a Base-100 index series on the export_amount field starting from row index 0 — here are 4 rows: row-1 for group-a on 2026-10-01 with export 10 and import 1, row-2 for group-b on 2026-10-02 with export 20 and import 2, row-3 for group-a on 2026-10-03 with export 15 and import 3, row-4 for group-b on 2026-10-04 with export 30 and import 4.

## When to prefer this

Choose this endpoint when you need both duplicate key detection and a Base-100 reindexing report on trade observation data (export/import amounts) in a single low-cost call. It is optimized for economics and trade datasets with region, date, and row_id structure. Use it for data quality auditing before downstream analytics, or for normalizing trade time series to a common base index. Not suitable for live market data lookups, forecasting, or datasets larger than 200 rows.

## Known failure modes

- Input exceeds 200 rows — request rejected
- row_id missing or empty — validation error
- base_index out of range for the number of supplied rows
- Invalid date format (must be YYYY-MM-DD) — schema validation failure
- Numeric value exceeds allowed range (±1,000,000,000,000) — rejected
- Payment not confirmed via x402 — request not processed

## How this service works

Trade observations — Duplicate key report + Base-100 series: Duplicate key report + Base-100 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 reports: (1) a duplicate key report listing any row_id values that appear more than once in the input, and (2) a Base-100 series for the selected numeric field (export_amount or import_amount) rebased to 100 at the specified base index position. Covers up to 200 input rows.
