ThreadQueryParams

filter narrows which threads are returned, using a LangSmith filter expression evaluated against each thread's root run. For example: has(tags, "production") or eq(status, "error"). See https://docs.langchain.com/langsmith/trace-query-syntax#filter-query-language for syntax.

max_start_time is the exclusive upper bound on thread activity (RFC3339 date-time). Defaults to now (UTC) when omitted.

min_start_time is the inclusive lower bound on thread activity (RFC3339 date-time). Defaults to 1 day before now (UTC) when omitted.

project_id is the tracing project UUID.

thread_filter narrows results using a LangSmith filter expression evaluated against each complete thread summary. Self-hosted deployments require LangSmith v0.17 or later; unsupported deployments return 501. See https://docs.langchain.com/langsmith/trace-query-syntax#filter-query-language for syntax.

trace_filter narrows results to threads containing at least one trace whose root run matches this LangSmith filter expression. Trace-level aggregate fields are evaluated using the complete trace summary. Self-hosted deployments require LangSmith v0.17 or later; unsupported deployments return 501. See https://docs.langchain.com/langsmith/trace-query-syntax#filter-query-language for syntax.

tree_filter narrows results to threads containing at least one trace with a matching run anywhere in its run tree. Self-hosted deployments require LangSmith v0.17 or later; unsupported deployments return 501. See https://docs.langchain.com/langsmith/trace-query-syntax#filter-query-language for syntax.
