# Get live cost breakdown for one conversation

> Returns the running LLM + tool-call cost for a single conversation, aggregated live from `public.llm_cost_events` (tenant-scoped). Includes per-model and per-agent breakdown plus a soft-budget alert evaluation against `organizations.settings.agent_defaults.soft_cost_per_conversation_usd`. Distinct from the hard per-conversation cost cap in `apps/agent-runtime`'s Redis meter — this is the READ side for the inbox detail panel and never blocks anything. Returns zero totals (never errors) on missing ledger rows, missing soft cap, or DB blip so the FE chip degrades to a hyphen rather than 5xx-ing the panel.
