## 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-exact-row-5725bb38 -d '<json body>'
```

Example prompt: Can you clean up these trading journal rows by normalising the string fields and removing any exact duplicate entries? I have 4 rows across two instrument groups — group-a and group-b — with dates from 2026-10-01 to 2026-10-04 and various entry/exit prices.

## When to prefer this

Choose this endpoint when you need to clean trading journal data offline — specifically to normalise string fields and remove exact duplicate rows — without any live market lookup, prediction, or external service dependency. It is well suited as a lightweight pre-processing step before downstream financial analysis, at a fixed low cost of $0.01 USDC for up to 200 rows and 2 reports.

## Known failure modes

- Fewer than 1 row supplied — validation error
- More than 200 rows submitted — request rejected
- Missing required fields (row_id, date, entry_price, exit_price, instrument_group) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- entry_price or exit_price outside allowed numeric range — validation error
- Payment not included or insufficient — x402 payment required response

## How this service works

Trading journal observations — String normalisation + Exact row deduplication: String normalisation + Exact row deduplication 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

Two analytical reports: one covering string normalisation results for text fields (e.g. instrument_group) and one covering exact row deduplication findings across all supplied trading journal rows. No live data, predictions, or external lookups are included — all analysis is performed locally on the supplied data.
