Refuel Applications API

  title: Refuel Cloud API
  description: >-
    REST API for the Refuel Cloud data-labeling and data-enrichment platform.
    Refuel deploys a Task as a versioned Application served behind a REST
    endpoint; callers submit rows of structured / semi-structured data to the
    application's label endpoint to transform (label, clean, enrich) them in
    realtime using the application's LLM guidelines. Authentication uses an API
    key passed as a Bearer token. The only endpoint documented with a concrete
    request shape in Refuel's public documentation is the application label
    endpoint; dataset, task, application-management, and model/finetuning
    operations are performed in the Refuel app and via the Python and JavaScript
    SDKs.

      summary: Transform rows with a deployed application
      description: >-
        Submit a JSON array of input rows to a deployed application to run LLM
        labeling / prediction in realtime. Each row is an object whose keys
        match the application's expected input fields. The application applies
        its Task guidelines and returns the transformed (labeled / enriched)
        output for each row. Subject to a documented rate limit of 300 requests
        per minute and up to 100 concurrent requests.
