# Travel Administration — Category Frequencies + Equal-Width Histogram

> Travel Administration — Category Frequencies + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Generates two analytical reports — category frequency counts and an equal-width histogram — for travel administration records containing trip_count and recorded_cost 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 travel-administration-category-frequencies-equal-width-histogram-5767cdd6 -d '<json body>'
```

Example prompt: Can you run a category frequency breakdown and equal-width histogram on my travel administration data — I have up to 50 rows with trip_count and recorded_cost fields, and I want the histogram split into 10 bins for the trip_count field?

## When to prefer this

Choose this endpoint when you need both a categorical frequency breakdown and a numeric histogram for travel administration data in a single API call at low cost ($0.01 USDC). It is ideal for offline/batch analysis of up to 200 rows of trip and cost records without requiring any external data sources or live lookups. Prefer this over general analytics tools when you specifically need the dual-report output (frequencies + histogram) for the travel operations domain.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (must match YYYY-MM-DD pattern)
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000)
- Missing required fields (row_id, team_group, date, trip_count, recorded_cost) in any row
- bin count outside 1–30 range
- Empty rows array — at least 1 row required
- Payment failure via x402 protocol

## How this service works

Travel administration — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram for supplied travel administration records (trip_count, recorded_cost). 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: (1) a category frequency table showing how often each category value (e.g. team_group) appears in the dataset, and (2) an equal-width histogram partitioning the selected numeric field (trip_count or recorded_cost) into the specified number of bins with counts per bin. Both reports are computed locally on the supplied data with no external lookups.
