> Knowledge Topic Labelled JSONL Export 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).

Accepts up to 200 labelled text records with knowledge-topic categories and returns a formatted JSONL file for local ML evaluation and naive-Bayes baseline training.

## 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 knowledge-topic-labelled-jsonl-export-9e07f22e -d '<json body>'
```

Example prompt: Export my labelled knowledge topic records as a JSONL file — I have about 30 documents tagged as setup, usage, troubleshooting, and reference that I want to use for local evaluation and a naive-Bayes baseline.

## When to prefer this

Choose this endpoint when you have pre-labelled knowledge topic text records and need a structured JSONL export for local ML evaluation, small dataset benchmarking, or naive-Bayes baseline training — specifically when your labels map to the four knowledge topic categories (setup, usage, troubleshooting, reference) and you do not need hosted model training or inference.

## Known failure modes

- Fewer than 2 records supplied — minimum item count not met
- More than 200 records supplied — exceeds maxItems limit
- Record missing required fields (id, text, or actual) — schema validation error
- Invalid enum value for 'actual' field — must be one of setup, usage, troubleshooting, reference
- Text exceeds 1000 character limit per record — truncation or rejection
- Payment not confirmed via x402 — request blocked before processing
