# Trading Journal Observations — Numeric Interval Filter + Base-100 Series

> Trading Journal Observations — Numeric Interval Filter + Base-100 Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Analyzes trading journal rows (entry_price, exit_price) by filtering records within a numeric interval and computing a Base-100 indexed series for the selected price field.

## 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-numeric-interval-filter-base-100-series-8a70242a -d '<json body>'
```

Example prompt: Take my trading journal entries below and give me two reports: first filter to only rows where entry_price is between 0 and 100, then build a Base-100 series starting from row index 0 — here are 4 trades: row-1 2026-10-01 group-a entry=10 exit=1, row-2 2026-10-02 group-b entry=20 exit=2, row-3 2026-10-03 group-a entry=15 exit=3, row-4 2026-10-04 group-b entry=30 exit=4.

## When to prefer this

Choose this endpoint when you have up to 200 rows of trading journal data (entry_price, exit_price) and need both a price-range filter and a Base-100 rebased series in a single $0.01 call, without requiring live market data, external lookups, or predictions. Prefer it over general analytics tools when working with structured trade records that already include instrument_group and date fields and you want two complementary reports in one round-trip.

## Known failure modes

- Rows array empty or missing required fields (row_id, instrument_group, date, entry_price, exit_price) — validation error
- base_index value exceeds the number of supplied rows — index out of bounds error
- entry_price or exit_price values outside ±1,000,000,000,000 range — schema validation failure
- date string not matching YYYY-MM-DD pattern — format error
- More than 200 rows submitted — maxItems exceeded error
- All values null for the selected field — base-100 series cannot be computed

## How this service works

Trading journal observations — Numeric interval filter + Base-100 series: Numeric interval filter + Base-100 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 reports computed locally on the supplied data: (1) a numeric interval filter listing all rows where the selected field (entry_price or exit_price) falls within the specified minimum–maximum range, and (2) a Base-100 indexed series rebasing the selected field relative to the value at the specified base_index row. Covers up to 200 input rows. No external data is fetched or predictions made.
