# Trading Journal Duplicate Key Report & Missing-Value Fill

> Trading Journal Duplicate Key Report & Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Analyzes up to 200 trading journal rows to produce a duplicate key report and fill missing entry_price or exit_price values using zero, mean, or median imputation.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-duplicate-key-report-missing-value-fill-2cc2fded -d '<json body>'
```

Example prompt: Check my trading journal for duplicate row IDs and fill any missing entry_price values using median imputation — here are my rows: row-1 AAPL 2024-01-15 entry=null exit=152.30, row-2 AAPL 2024-01-15 entry=148.00 exit=152.30, row-3 MSFT 2024-01-16 entry=310.00 exit=null, row-3 MSFT 2024-01-16 entry=310.00 exit=315.50.

## When to prefer this

Choose this endpoint when you need a combined duplicate-detection and missing-value imputation pass on trading journal data in a single low-cost call ($0.01 USDC for both reports). It is ideal for pre-processing trade logs before backtesting, reconciliation, or analysis when you need offline, deterministic computation on your own data without any external lookups or predictions.

## Known failure modes

- Submitting more than 200 rows returns a validation error
- Missing required fields (row_id, instrument_group, date) cause row-level rejection
- Invalid date format (not YYYY-MM-DD) triggers a pattern validation failure
- Selecting a fill method not in [zero, mean, median] returns an enum error
- Submitting fewer than 1 row returns a minItems validation error
- Price values outside ±1,000,000,000,000 are rejected by schema bounds

## How this service works

Trading journal observations — Duplicate key report + Explicit missing-value fill: Duplicate key report + Explicit missing-value fill 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 reports: (1) a duplicate key report identifying which row_id values appear more than once across the submitted rows, and (2) a missing-value fill report showing which entry_price or exit_price cells were null and what values were substituted using the chosen method (zero, mean, or median). Both reports are computed locally on the supplied data with no external lookups.
