  title: px0 API
  description: >
    px[0] is an open-source prompt infrastructure toolkit for managing prompts
    in production. It replaces hardcoded prompt strings with versioned
    templates, in-process caching, and OpenTelemetry observability, so teams can
    iterate on prompts without touching application code. This is the OpenAPI
    specification for all the public APIs of px0.
