Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • create_endpoint

    Register an LLM endpoint to monitor. The workspace must already have a stored API key for the provider (use the dashboard to add one). Returns the new endpoint's id.

  • create_spec

    Create a behavioral spec. The first run after creation sets the baseline output; subsequent scheduled runs are scored against that baseline across 5 axes (semantic, format, refusal, length, contains). Provide a semantic similarity threshold or use the API default.

  • get_drift_events

    Fetch recent drift events across the workspace, newest first. Each event has spec_id, run_id, severity, drift_score, summary, and created_at. Use this for weekly review or to drive an automation.

  • get_health

    Per-spec health across the workspace: spec_id, spec_name, endpoint_name, status (green/yellow/red), last_drift_score and last_run_at. This is not a plan or billing KPI endpoint.

  • get_spec_history

    Get the run history for a single spec. Returns each run's status, drift score, semantic similarity, format match, and timestamp — useful for trending charts and reasoning about when behavior shifted.

  • list_endpoints

    List the LLM endpoints currently monitored in this workspace. Returns id, name, provider, model, is_active, created_at for each.

  • list_specs

    List behavioral specs in the workspace. A spec is a stored prompt + expectation that ModelWatch replays on a schedule and diffs against a baseline. Returns id, name, input_text, schedule, has_baseline, and the parent endpoint_id.

  • reset_baseline

    Clear a spec's baseline. The next run will record a new baseline instead of being diffed against the old one. Use this after you've intentionally changed your prompt template, model version, or the behavior you expect — otherwise every future run will look like drift.

  • run_spec

    Run a spec on demand and return the drift score immediately. Use this to (1) set the baseline manually right after create_spec, or (2) sanity-check a spec without waiting for the next scheduled run. Returns the run status, output, drift score, semantic similarity, format match, refusal flag, and timestamp.
