# Trading Journal Observations — Record Quality Audit + String Normalisation + Two-Measure Correlation

> Trading Journal Observations — Record Quality Audit + String Normalisation + Two-Measure Correlation 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 trading journal rows (entry_price, exit_price): a record quality audit, string normalisation, and two-measure correlation — no external lookups or predictions.

## 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-c3a58fa6 -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and entry-vs-exit price correlation on my trading journal? Here are up to 200 rows with row IDs, instrument groups, dates, entry prices, and exit prices — I want all three reports back in one shot.

## When to prefer this

Choose this endpoint when you need to validate, normalise, and analyse the statistical relationship between entry and exit prices in a trading journal dataset of up to 200 rows, and want all three reports (quality audit, string normalisation, correlation) returned in a single API call at low cost. Prefer this over generic data quality tools when your data model specifically matches the trading journal schema (entry_price, exit_price, instrument_group). Not suitable if you need live market data, predictions, or professional financial advice.

## Known failure modes

- Fewer than 1 row submitted — minItems violation returns validation error
- More than 200 rows submitted — maxItems violation returns validation error
- Missing required fields (row_id, instrument_group, date, entry_price, exit_price) on any row — schema validation error
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- entry_price or exit_price outside allowed numeric range — schema validation error
- Payment not included or insufficient — x402 payment required error

## How this service works

Trading journal observations — Record quality audit + String normalisation + Two-measure correlation: Record quality audit + String normalisation + Two-measure correlation 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 independent analytical reports for the submitted trading journal rows: (1) a record quality audit flagging missing, null, or malformed field values; (2) a string normalisation report for instrument_group and other string fields; (3) a two-measure correlation report between entry_price and exit_price. All computed locally with no external lookups.
