## 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-string-normalisation-grouped-numeric-c259c37b -d '<json body>'
```

Example prompt: Can you normalize the instrument group labels and give me a grouped numeric summary of entry_price for these 4 trades: row-1 on 2026-10-01 in group-a with entry 10 and exit 1, row-2 on 2026-10-02 in group-b with entry 20 and exit 2, row-3 on 2026-10-03 in group-a with entry 15 and exit 3, and row-4 on 2026-10-04 in group-b with entry 30 and exit 4?

## When to prefer this

Choose this endpoint when you need offline, deterministic string normalization and grouped numeric summarization of trading journal data (entry/exit prices by instrument group) for up to 200 rows, without needing live market data, predictions, or external API calls. Ideal for post-trade batch reporting, journal cleanup, and per-group statistical summaries at low cost ($0.01 USDC for two reports).

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, instrument_group, date, entry_price, exit_price) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema validation failure
- Numeric values outside allowed range (-1e12 to 1e12) are rejected
- Empty rows array returns an error
- Invalid field enum value (not entry_price or exit_price) causes failure

## How this service works

Trading journal observations — String normalisation + Grouped numeric summary: String normalisation + Grouped numeric summary for supplied trading journal observations records (entry_price, exit_price). 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

Returns two analytical reports: (1) a string normalization report for the instrument group and related string fields, and (2) a grouped numeric summary of the selected price field (entry_price or exit_price) organized by instrument_group, including statistics such as counts, means, and distributions per group. Both reports are computed locally with no external lookups.
