console.log(result.classifications);

curl http://localhost:8080/v1/extract/facebook%2Fbart-large-mnli \

  -d "{\"items\":[{\"text\":\"The renewal charged me twice but the receipt link is broken.\"}],\"params\":{\"labels\":[\"billing\",\"bug report\",\"feature request\",\"account access\"]}}"

Build the "Classify" capability into my app using the Superlinked Inference Engine (SIE).

Context
- SIE is an OpenAI-style inference API. Python SDK: `from sie_sdk import SIEClient`; TypeScript: `@superlinked/sie-sdk`.
- Base URL: http://localhost:8080, my own SIE server, which takes no API key.
- Model: facebook/bart-large-mnli (SIE primitive: /extract). Keep the model id configurable.

Task
- Input: a block of text plus a set of candidate labels.
- Behaviour: return the best-matching label(s) with native scores
- Call the selected SIE primitive once per request and map the response into your domain type.

Deliverables
- A typed client wrapper, an application-level function for this task, error handling for timeouts/empty input, and unit tests with a stubbed client.
- Wire it into my existing stack (ask me which framework if unclear) and add a short usage example.
