# Trade Observations Data Quality Suite: Record Audit + Deduplication + Histogram

> Trade Observations Data Quality Suite: Record Audit + Deduplication + Histogram 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).

Runs three local analytical reports on trade observation records — record quality audit, exact row deduplication, and equal-width histogram — for export_amount and import_amount fields.

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-data-quality-suite-record-audit-deduplication-ad3e12ba -d '<json body>'
```

Example prompt: Can you run a full data quality check on my trade observations — I have 50 rows with export_amount and import_amount fields, and I'd like a record quality audit, exact duplicate detection, and a histogram of export_amount with 10 bins?

## When to prefer this

Use this endpoint when you need simultaneous data quality auditing, deduplication, and distribution analysis on trade observation records (export_amount, import_amount) in a single low-cost call. Prefer it over separate profiling tools when your dataset is under 200 rows and you want three reports bundled at $0.01 USDC. Best for pre-processing pipelines, data validation gates, or exploratory data profiling on economics or trade datasets.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Invalid date format not matching YYYY-MM-DD pattern causes row rejection
- Missing required fields (row_id, region, date) causes schema validation failure
- Bin count outside 1–30 range returns parameter error
- Numeric values outside ±1 trillion range rejected
- Empty rows array returns error

## How this service works

Trade observations — Record quality audit + Exact row deduplication + Equal-width histogram: Record quality audit + Exact row deduplication + Equal-width histogram for supplied trade observations records (export_amount, import_amount). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Three independent analytical reports: (1) a record quality audit flagging null values, format violations, and completeness issues per row; (2) an exact row deduplication report identifying identical records; and (3) an equal-width histogram showing bin ranges and frequency counts for the selected numeric field (export_amount or import_amount). All computed locally with no external data access.
