## 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 trading-journal-observations-record-quality-audit-string-6808ad10 -d '<json body>'
```

Example prompt: Can you run a data quality audit, string normalisation, and numeric distribution analysis on my trading journal — here are 10 rows with row IDs, dates in YYYY-MM-DD format, instrument groups like 'equities' and 'forex', and entry_price and exit_price values — focus the numeric distribution on entry_price?

## When to prefer this

Choose this endpoint when you need a bundled, low-cost ($0.01 USDC) set of three data profiling reports — quality audit, string normalisation, and numeric distribution — on a batch of up to 200 trading journal records. It is ideal for pre-processing pipelines where you want to validate and profile raw trade data (entry_price, exit_price) before downstream analysis, without requiring any external data sources, predictions, or professional assessments. Prefer it over building custom profiling logic when the specific combination of these three report types covers your needs.

## Known failure modes

- Rows array is empty or exceeds 200 items — validation error returned
- Required fields (row_id, date, entry_price, exit_price, instrument_group) missing from one or more rows — schema validation failure
- Date field does not match YYYY-MM-DD pattern — row rejected or flagged
- Price values outside the allowed range (±1,000,000,000,000) — schema rejection
- Invalid field selector (not 'entry_price' or 'exit_price') — enum validation error
- Payment of 0.01 USDC not completed — 402 Payment Required response

## How this service works

Trading journal observations — Record quality audit + String normalisation + Numeric distribution: Record quality audit + String normalisation + Numeric distribution for supplied trading journal observations records (entry_price, exit_price). 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 structured analytical reports: (1) a record quality audit flagging nulls, missing fields, and anomalies across rows; (2) a string normalisation report standardising text fields like instrument_group and date formatting; and (3) a numeric distribution report for the selected price field (entry_price or exit_price), including statistical summaries across up to 200 supplied rows. All analysis is performed locally with no external lookups.
