# Trading Journal Observations — Date×Category Pivot + Keyed Dataset Comparison

> Trading Journal Observations — Date×Category Pivot + Keyed Dataset Comparison 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 by producing a date-by-instrument-group pivot table and a keyed comparison between two supplied datasets 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-date-category-pivot-keyed-dataset-45fa4305 -d '<json body>'
```

Example prompt: Take my two sets of trading journal records — the primary dataset and a comparison dataset — and run both a date-by-instrument-group pivot and a keyed dataset comparison on the entry_price field; each dataset has up to 200 rows with row_id, instrument_group, date, entry_price, and exit_price.

## When to prefer this

Choose this endpoint when you need both a date-by-category pivot table and a keyed dataset comparison in a single call for trading journal data with entry and exit prices. It is ideal for comparing two snapshots of trade records (e.g., from different systems or time periods) while also summarizing price data across instrument groups and dates — all without sending data to external services or requiring live market feeds.

## Known failure modes

- Missing required fields (row_id, instrument_group, date, entry_price, exit_price) cause validation errors
- Exceeding 200 rows per dataset triggers a row limit rejection
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Null values in entry_price or exit_price may affect pivot aggregation results
- Mismatched row_ids between primary and comparison datasets result in unmatched rows in the comparison report
- Payment of 0.01 USDC required; missing or failed payment returns 402 error

## How this service works

Trading journal observations — Date by category pivot + Keyed dataset comparison: Date by category pivot + Keyed dataset comparison 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 date-by-instrument-group pivot table showing aggregated entry_price or exit_price values for each date/category combination, and (2) a keyed comparison report highlighting differences between the primary and secondary datasets matched by row_id, both computed locally without external data lookups.
