Refuel

Refuel is an AI data-labeling and data-enrichment platform that uses LLMs to label, clean, structure, and enrich enterprise datasets. Refuel Cloud exposes a REST API where datasets, tasks, and deployed applications transform new data in realtime, and the open-source autolabel library lets teams run the same LLM labeling workflows in their own environment.

Refuel publishes 1 API on the APIs.io network: Applications API. Tagged areas include AI, LLM, Data Labeling, Data Enrichment, and Autolabel.

Refuel’s developer surface includes authentication, documentation, and 10 more developer resources.
