# Cancellation Reason Supplied-Group Evaluation

> Cancellation Reason Supplied-Group Evaluation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Evaluates a supplied set of up to 200 labelled text records for cancellation reason classification, computing per-group metrics and naive-Bayes baselines without hosted model training.

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 cancellation-reason-supplied-group-evaluation-f8eb9362 -d '<json body>'
```

Example prompt: Evaluate my cancellation reason predictions by group — I have 120 labelled records, each with an actual label (price, usage, quality, or other), a predicted label, and a group field for customer segment. Can you run the supplied-group evaluation and show me the per-group performance metrics?

## When to prefer this

Choose this endpoint when you have a small, locally-held labelled dataset (up to 200 records) of cancellation reason text, already have predicted labels from your own model, and need fast per-group evaluation metrics and a naive-Bayes baseline without sending data to a hosted model or foundation model trainer. Ideal for lightweight audits, fairness checks across customer segments, and quick benchmarking of churn classifiers.

## Known failure modes

- More than 200 records supplied — request exceeds the bounded evaluation limit
- Missing required fields (id, text, actual, predicted, group) on any record causes validation failure
- Invalid enum values for actual or predicted fields (must be price, usage, quality, or other)
- Empty records array returns no meaningful evaluation output
- Malformed JSON input results in a 400-level error

## How this service works

Cancellation reason - Supplied-group evaluation: Supplied-group evaluation 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 supplied-group evaluation deliverable.

## Output

Returns a bounded group-level evaluation deliverable including per-group classification metrics (such as accuracy, precision, recall) for each combination of group label and cancellation reason category, plus a naive-Bayes baseline comparison, computed from up to 200 supplied labelled text records.
