# Language Routing — Train Local Text Baseline and Classify

> Language Routing — Train Local Text Baseline and Classify 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 (english/french/spanish/other) and classifies new query texts against that local model.

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 language-routing-train-local-text-baseline-and-classify-252f84c3 -d '<json body>'
```

Example prompt: Train a local naive-Bayes language classifier on these labelled text samples — I have 12 examples (4 english, 4 french, 4 spanish) — and then classify these two new query texts: 'Bonjour le monde' and 'Hello world'.

## When to prefer this

Choose this endpoint when you need a cheap, disposable, local text classification baseline for language routing without relying on a hosted or foundation model. Ideal for small datasets (up to 200 records), rapid prototyping, or cost-sensitive pipelines where a naive-Bayes approximation is sufficient. Prefer alternatives if you need high accuracy on multilingual text, support for languages beyond english/french/spanish/other, or a persistent hosted model.

## Known failure modes

- Fewer than 2 labelled records supplied — minimum input not met
- More than 200 records provided — exceeds maximum and will be rejected
- Query texts array is empty or exceeds 20 items
- Text fields exceed 1000 characters — truncation or rejection
- Only one class present in training data — classifier cannot generalise
- Payment of 0.01 USDC not attached — 402 payment required response
- Invalid label value outside enum (english/french/spanish/other)

## How this service works

Language routing - Train local text baseline and classify: Train local text baseline and classify for Language routing. 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 query text (predicted language label from english/french/spanish/other), along with evaluation metrics for the trained naive-Bayes baseline model derived from the supplied labelled records.
