}Query
Fetch the recorded trace for a query turn
The per-turn debug trace (steps, tool calls, strategy, cost, rollup). Trace persistence is unconditional — every turn lands a trace blob — so this is available once the turn is terminal.

bearerAuthapiKey
Session token from POST /auth/login, sent as Authorization: Bearer <token>.
Headers
Date-based contract version, echoed back on the same header. Omit for the default (2026-07); send unstable for the in-development surface. An unrecognized value is rejected with 400 unsupported_api_version.
Path Parameters
Query turn id.
Response
The trace document
A turn's full-fidelity debug trace. Every turn lands one.
