# Trading Journal Observations — Duplicate Key Report + Trailing Mean Series

> Trading Journal Observations — Duplicate Key Report + Trailing Mean Series 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).

Analyzes up to 200 trading journal rows to produce a duplicate key report and a trailing mean series for entry_price or exit_price fields.

## 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-duplicate-key-report-trailing-mean-series-4132730c -d '<json body>'
```

Example prompt: Check my trading journal for duplicate keys and compute a trailing mean over a window of 5 for entry_price — here are my rows: row-1 on 2026-10-01 for group-a with entry 10 and exit 1, row-2 on 2026-10-02 for group-b with entry 20 and exit 2, row-3 on 2026-10-03 for group-a with entry 15 and exit 3.

## When to prefer this

Choose this endpoint when you need both duplicate key detection and trailing mean computation on trading journal data (entry_price or exit_price) in a single call for up to 200 rows. It is ideal for lightweight, offline data quality audits and rolling average analytics on trade records without needing live market data, predictions, or external lookups.

## Known failure modes

- Fewer than 1 row provided — validation error
- More than 200 rows submitted — rejected with max items error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Window size outside 2–200 range — validation error
- Null values in entry_price or exit_price may affect trailing mean computation
- Missing required fields (row_id, instrument_group, date) — schema error

## How this service works

Trading journal observations — Duplicate key report + Trailing mean series: Duplicate key report + Trailing mean series 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 independent analytical reports: (1) a duplicate key report identifying any rows that share the same key fields, and (2) a trailing mean series showing the rolling average of the selected price field (entry_price or exit_price) over the specified window size, computed across up to 200 supplied trading journal rows.
