# Ticket Priority Grouped Three-Fold Baseline Cross-Validation

> Ticket Priority Grouped Three-Fold Baseline Cross-Validation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Runs a grouped three-fold cross-validation on up to 200 labelled support ticket texts to evaluate a naive-Bayes classifier's accuracy at predicting low, normal, or high priority.

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 ticket-priority-grouped-three-fold-baseline-cross-validation-1fe42e40 -d '<json body>'
```

Example prompt: Run a grouped three-fold baseline cross-validation on my 50 labelled support tickets — I've got the ticket text and priority labels (low, normal, or high) for each — and tell me how accurately the naive-Bayes model predicts priority.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) sanity-check or baseline accuracy estimate for a ticket priority text classification task using your own labelled data, before committing to training a full model. It is ideal for small datasets (up to 200 records) where you want to assess learnability using a naive-Bayes baseline with grouped three-fold cross-validation, without any hosted model or foundation-model overhead.

## Known failure modes

- Fewer than 2 records supplied — minimum input not met
- More than 200 records supplied — exceeds maximum item limit
- Missing required fields (id, text, or actual) on any record
- Invalid priority label value outside enum (low, normal, high)
- Insufficient class distribution across folds for meaningful evaluation
- Record text exceeds 1000-character maximum

## How this service works

Ticket priority - Grouped three-fold baseline evaluation: Grouped three-fold baseline evaluation for Ticket priority. 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 grouped three-fold baseline evaluation deliverable.

## Output

A grouped three-fold baseline evaluation result containing cross-validation accuracy metrics computed by a local naive-Bayes classifier over the supplied labelled records, indicating how well ticket text predicts low, normal, or high priority across the three folds.
