# Train Local Text Baseline and Classify (Task Type)

> Train Local Text Baseline and Classify (Task Type) 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).

Trains a naive-Bayes text classifier on up to 200 labelled records across task-type categories (research, writing, analysis, implementation) and classifies query texts.

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 train-local-text-baseline-and-classify-task-type-d2f8b7ad -d '<json body>'
```

Example prompt: I have about 50 labelled task descriptions tagged as research, writing, analysis, or implementation — can you train a naive-Bayes classifier on them and then classify these three new task texts: 'summarize academic papers on NLP', 'write a blog post draft', 'implement the authentication module'?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC), local naive-Bayes text classification baseline for task-type categorization without requiring a hosted or foundation model. Ideal for prototyping, sanity-checking labels, or routing task descriptions at small scale (up to 200 examples). Prefer this over foundation-model endpoints when cost, simplicity, and interpretability matter more than accuracy, or when you want a reproducible baseline before investing in larger models.

## Known failure modes

- Fewer than 2 labelled records supplied — minimum input not met, request rejected
- More than 200 labelled records submitted — exceeds maxItems limit
- Query texts array is empty or missing — at least 1 query text required
- Text field exceeds 1000 characters — truncation or rejection of that record
- Invalid or missing 'actual' enum value — must be one of: research, writing, analysis, implementation
- Insufficient class coverage in training set — classifier may perform poorly if only one category is represented

## How this service works

Task type - Train local text baseline and classify: Train local text baseline and classify for Task type. 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 train local text baseline and classify deliverable.

## Output

The endpoint returns classification predictions for each submitted query text, based on a naive-Bayes model trained locally on the supplied labelled records. Results include the predicted task-type label (research, writing, analysis, or implementation) for each query, along with any evaluation metrics available from the local dataset tools.
