Path Parameters

​
trace_id

Trace UUID

Query Parameters

​
filter
string

filter narrows which runs within this trace are returned, using a LangSmith filter expression evaluated against each run. For example: eq(run_type, "llm") for LLM runs only, or eq(status, "error") for failed runs. See https://docs.langchain.com/langsmith/trace-query-syntax#filter-query-language for syntax.

​
max_start_time
string<date-time>
required

max_start_time is the inclusive upper bound for run start_time (RFC3339 date-time).

​
min_start_time
string<date-time>
required

min_start_time is the inclusive lower bound for run start_time (RFC3339 date-time).

​
project_id
string<uuid>
required

project_id is the UUID of the tracing project that owns the trace.

​
