  title: Waxell Observe Cost Management Runs API
  description: 'The Waxell Observe REST API exposes the AI agent governance and

    observability control plane. It is used by the `waxell-observe` Python

    SDK and Developer MCP server to record agent runs, log LLM calls and

    spans, evaluate runtime governance policies, manage prompts, and

    administer model cost tables.


    Endpoints are served from a tenant-specific control plane host

    (e.g. `https://acme.waxell.dev`) at the path prefix

    `/api/v1/observe/`. Authentication uses the same `wax_sk_` keys

    issued in the dashboard, presented either as `X-Wax-Key` or as a

    `Bearer` token.
