About
classifier.dev is a zero-shot text classification API reachable over plain HTTP: send text and a list of labels, get back the best-fitting label and a confidence score. It requires no API key or account for free use and offers two model lanes, Jev and a newer Laya model in trial, with fast single-decision and bulk batch processing modes plus agent-oriented discovery files (OpenAPI spec, skill manifest).
What it does
The site describes a hosted classification service: a caller sends text with candidate labels, or a block of state with typed questions, and gets a structured answer. Its page also lists image, audio and video models, a paid mode that scrapes a public web page before classifying it, and support for the TypeSafe client libraries.

- The page refers to this repository's CLI but does not link the repository it means.
- Prices for the Pro and Scale workspace plans are not shown on this page.
- The page calls Laya and Kev a trial without saying when the trial ends or what they will cost after it.
