# Cancellation Reason Label Distribution

> Cancellation Reason Label Distribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes the label distribution (class balance) across up to 200 labelled cancellation-reason text records tagged as price, usage, quality, or other.

## 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 cancellation-reason-label-distribution-34249ddc -d '<json body>'
```

Example prompt: I have 150 labelled cancellation reason records tagged as price, usage, quality, or other — can you check the label distribution to see if the classes are balanced before I train a classifier?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01) label distribution audit on a small labelled dataset (up to 200 records) with cancellation reason categories (price, usage, quality, other) — especially useful before training a naive-Bayes or similar classifier to detect class imbalance without spinning up a hosted model.

## Known failure modes

- Fewer than 2 records submitted — minimum record count not met
- Record count exceeds 200 — maximum items limit exceeded
- Missing required fields (id, text, or actual) on one or more records
- Invalid enum value for 'actual' field (must be price, usage, quality, or other)
- Payment not included or insufficient — x402 payment required
- Record ID exceeds 80 character limit or is empty

## How this service works

Cancellation reason - Label distribution: Label distribution for Cancellation reason. Up to 200 supplied labelled text records. Local dataset tools, evaluation and small naive-Bayes baselines; no hosted model or foundation-model training. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded label distribution deliverable.

## Output

Returns a label distribution summary showing the count and/or proportion of records falling into each cancellation reason category (price, usage, quality, other) across the submitted dataset of up to 200 labelled records.
