## 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-record-quality-audit-category-frequencies-107938d0 -d '<json body>'
```

Example prompt: Can you run a record quality audit and category frequency analysis on my trade observations? I have 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, and 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 a data quality audit and category frequency analysis on trade observation records (export/import amounts) in a single call at minimal cost. It is purpose-built for economics/trade datasets with region and date dimensions. Prefer it over generic data profiling tools when working within the x402 micropayment ecosystem and when your dataset fits within 200 rows.

## Known failure modes

- Fewer than 1 row submitted returns validation error
- More than 200 rows submitted exceeds limit and is rejected
- Row missing required fields (row_id, region, date, export_amount, import_amount) causes schema validation failure
- Date field not matching YYYY-MM-DD pattern causes parsing error
- Numeric values outside ±1,000,000,000,000 range are rejected
- Payment of 0.01 USDC not provided or fails x402 protocol results in 402 response

## How this service works

Trade observations — Record quality audit + Category frequencies: Record quality audit + Category frequencies 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

Two independent analytical reports: (1) a record quality audit highlighting data completeness, null values, formatting issues, and anomalies in the export_amount and import_amount fields; and (2) a category frequency report showing how records are distributed across categories such as region and date, for up to 200 input rows.
