# Lead Stage Labelled JSONL Export

> Lead Stage 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).

Exports up to 200 labelled text records tagged with CRM lead stage classes (enquiry, qualified, negotiation, closed) as a JSONL file for local ML evaluation and naive-Bayes baseline 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 lead-stage-labelled-jsonl-export-fc0203f4 -d '<json body>'
```

Example prompt: Export my 150 labelled lead stage records as a JSONL file — each record has an ID, the text, and the actual stage label (enquiry, qualified, negotiation, or closed) — so I can use it locally to train a naive-Bayes classifier.

## When to prefer this

Choose this endpoint when you need a cost-effective ($0.01), bounded JSONL export of labelled lead stage text records for local ML workflows — specifically when working with the four CRM pipeline stages (enquiry, qualified, negotiation, closed). Prefer it over generic data export tools when you want a pre-structured, annotation-ready file compatible with naive-Bayes and other lightweight classifiers, without needing a hosted model or cloud training environment.

## Known failure modes

- Fewer than 2 records supplied — minimum item count not met
- More than 200 records submitted — exceeds maxItems limit
- Invalid stage label provided — must be one of enquiry, qualified, negotiation, closed
- Record ID missing or empty — required field not present
- Text field exceeds 1000 characters per record — truncation or rejection
- Malformed JSON in request body — 400 parse error
- Payment not included or insufficient — x402 payment required at $0.01 USDC

## How this service works

Lead stage - Labelled JSONL export: Labelled JSONL export for Lead stage. 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 labelled jsonl export deliverable.

## Output

A bounded JSONL export containing up to 200 labelled records, each line including the record ID, input text, and the actual lead stage label (one of: enquiry, qualified, negotiation, closed). Suitable for local dataset tooling, offline evaluation, and training simple classification baselines.
