TraceQueryParams

Body param: max_start_time is the upper bound for run start_time (RFC3339). Defaults to now.

Body param: min_start_time is the lower bound for run start_time (RFC3339). Defaults to 1 day ago.

project_id is the tracing project UUID this run was logged to.

Body param: trace_filter narrows results to runs whose root trace matches this LangSmith filter expression. Use this to filter by properties of the trace's root run — for example eq(status, "success") to include only traces that completed without error. See https://docs.langchain.com/langsmith/trace-query-syntax#filter-query-language for syntax.

trace_ids is an optional fast-path restriction to a known set of trace UUIDs. Equivalent in result to including each UUID in a trace_filter, but more efficient at scale.

Body param: tree_filter narrows results to runs that belong to a trace containing at least one run matching this LangSmith filter expression anywhere in the run tree (not just the root). Use this to find runs inside traces that involved a specific tool, tag, or model — for example has(tags, "production") or eq(name, "my_tool"). See https://docs.langchain.com/langsmith/trace-query-syntax#filter-query-language for syntax.
