# Reading Activity String Normalisation and Numeric Row Ordering

> Reading Activity String Normalisation and Numeric Row Ordering is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Normalises string fields and applies numeric row ordering to supplied reading activity records (pages_read, reading_minutes) across up to 200 rows, producing 2 analytical reports.

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 reading-activity-string-normalisation-and-numeric-row-ordering-066b9126 -d '<json body>'
```

Example prompt: Take my reading activity records — row-1 on 2026-10-01 with 10 pages and 1 minute for group-a, row-2 on 2026-10-02 with 20 pages and 2 minutes for group-b — normalise the course_group strings and give me the rows ordered numerically by pages_read.

## When to prefer this

Choose this endpoint when you have up to 200 reading activity records and need both string normalisation of categorical fields and numeric ordering of quantitative fields in a single low-cost call. It is ideal for education analytics pipelines where data cleaning and ranking are needed before downstream reporting, and no live data lookup or prediction is required.

## Known failure modes

- Exceeding 200 rows returns an error or truncation
- Missing required fields (row_id, date, pages_read, reading_minutes) causes validation failure
- Invalid date format (not YYYY-MM-DD) triggers a pattern mismatch error
- Invalid field enum value (anything other than pages_read or reading_minutes) rejected
- Empty rows array not accepted (minItems: 1)
- Numeric values outside allowed range cause rejection

## How this service works

Reading activity — String normalisation + Numeric row ordering: String normalisation + Numeric row ordering for supplied reading activity records (pages_read, reading_minutes). 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 for the supplied reading activity rows: one applying string normalisation to text fields (such as course_group), and one ordering the rows numerically by the selected field (pages_read or reading_minutes). No external lookups or predictions are made; all processing is local.
