  title: Freeplay HTTP Agents Sessions API
  description: The Freeplay HTTP API provides programmatic access to the Freeplay LLM experimentation, evaluation, and observability platform. It covers prompt template management, recording completions and sessions/traces, curating test cases and datasets, running batch test runs and evaluations, and recording customer and human feedback. The API root is your Freeplay instance URL plus /api/v2. For the standard cloud instance this is https://app.freeplay.ai/api/v2; private/self-hosted instances use a per-account subdomain such as https://{subdomain}.freeplay.ai/api/v2.
