# Trade Observations Record Quality Audit and String Normalisation

> Trade Observations Record Quality Audit and String Normalisation 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).

Audits trade observation records (export_amount, import_amount) for data quality issues and normalises strings, producing two independent analytical reports for 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-record-quality-audit-and-string-normalisation-2052b559 -d '<json body>'
```

Example prompt: Can you run a record quality audit and string normalisation on my trade observations dataset? I have rows with row_id, region, date, export_amount, and import_amount fields — here are my records — and I need both reports back.

## When to prefer this

Choose this endpoint when you need simultaneous record quality auditing and string normalisation specifically for trade observation data containing export_amount and import_amount fields, and you want two separate reports in a single low-cost call. It is best suited for batch sizes up to 200 rows where no live lookup, prediction, or external data enrichment is needed — purely local analytical processing of supplied data.

## Known failure modes

- Payload exceeds 200 rows — endpoint rejects with validation error
- Missing required fields (row_id, region, date, export_amount, import_amount) cause row-level rejection
- Malformed date strings not matching YYYY-MM-DD pattern may trigger schema validation failure
- Numeric values outside ±1,000,000,000,000 range are rejected by schema
- Empty rows array (minItems:1 violated) returns error
- Payment of 0.01 USDC not provided or x402 protocol failure blocks request

## How this service works

Trade observations — Record quality audit + String normalisation: Record quality audit + String normalisation 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 flagging issues such as nulls, out-of-range values, malformed dates, and inconsistencies in the trade observation fields; and (2) a string normalisation report showing how region and other string fields have been standardised. Both reports cover up to 200 input rows and are computed locally without any external lookups.
