# Tutoring Sessions — Category Frequencies + Numeric Interval Filter

> Tutoring Sessions — Category Frequencies + Numeric Interval Filter is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Analyzes tutoring session records to produce category frequency counts by course group and a numeric interval filter report for session_minutes or session_count fields.

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 tutoring-sessions-category-frequencies-numeric-interval-filter-5ec3cf51 -d '<json body>'
```

Example prompt: Analyze my tutoring session data — I have up to 50 rows with course groups like 'math' and 'science', and I want two reports: frequency counts per course group, and a filter showing only sessions where session_minutes is between 30 and 90.

## When to prefer this

Choose this endpoint when you have up to 200 tutoring session records and need both a categorical frequency breakdown by course group AND a numeric range filter on session metrics in a single API call. It is ideal for lightweight, self-contained analytics on supplied data without needing a full data warehouse or BI tool. Prefer this over general analytics platforms when cost sensitivity matters (0.01 USDC for two reports) and when your data is already structured with course_group, date, session_minutes, and session_count fields.

## Known failure modes

- More than 200 rows submitted — request rejected due to row limit
- Missing required fields (row_id, course_group, date, session_minutes, session_count) on any row — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema validation failure
- minimum greater than maximum — may return empty interval filter result
- Non-numeric values in session_minutes or session_count — type validation error
- Empty rows array — rejected due to minItems:1 constraint

## How this service works

Tutoring sessions — Category frequencies + Numeric interval filter: Category frequencies + Numeric interval filter for supplied tutoring sessions records (session_minutes, session_count). 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 derived from the supplied tutoring session rows: (1) a category frequency table showing how many records belong to each course_group value, and (2) a numeric interval filter report listing rows where the selected field (session_minutes or session_count) falls within the specified minimum–maximum range. No external data is fetched; all computation is local to the engine.
