How this service works
Lead stage - Train local text baseline and classify: Train local text baseline and classify 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 train local text baseline and classify deliverable.
Output
Returns predicted lead-stage labels (enquiry, qualified, negotiation, or closed) for each submitted query text, along with evaluation metrics from the trained naive-Bayes model such as accuracy or per-class scores derived from the supplied labelled dataset.
Example use cases
CRM note pipeline stage tagger
“I have 80 past sales notes each labelled as enquiry, qualified, negotiation, or closed. Train a classifier on those and tell me which stage these 5 new prospect emails belong to.”
Sales lead scoring baseline
“Can you build a quick text baseline model from my 120 labelled lead records and evaluate how well it can predict whether a new inbound message is an enquiry or already qualified?”
Automated deal stage detector
“I've got 150 annotated conversation snippets from our pipeline — labelled as enquiry, qualified, negotiation, or closed. Train a local classifier and run it against these 10 new chat transcripts so I know what stage each deal is at.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-ml-lead-stage-local-classifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, local naive-Bayes baseline classifier for CRM lead-stage categorisation without access to a hosted model or LLM. Ideal for small datasets (up to 200 records), quick pipeline-stage prototyping, or cost-sensitive automation where $0.01 per run and a bounded, interpretable model are acceptable tradeoffs.
Side effects
- Fewer than 2 labelled records supplied — minimum input requirement not met
- Missing required fields (id, text, actual) in any record — validation error
- Text exceeds 1000-character limit per record — truncation or rejection
- Fewer than 1 or more than 20 query texts supplied — out-of-range error
- Class imbalance in training data leading to poor classification of minority stages
- Payment not processed (402 response) — x402 payment required before classification is run
