    Agenta is an open-source LLMOps platform for prompt management, LLM
    evaluation, and LLM observability. This specification documents the public
    cloud REST API surface used to manage applications and variants, fetch and
    deploy versioned prompt configurations, run evaluations and configure
    evaluators, manage testsets, and ingest and query observability traces. All
    endpoints are authenticated with an Agenta API key passed in the
    Authorization header. Agenta is MIT licensed and may also be self-hosted.
