Authorizations

​
Authorization
string
header
required

Basic authentication header of the form Basic <encoded-value>, where <encoded-value> is the base64-encoded string username:password.

Body

application/json
​
project_id
string
required
Examples:

"entity/project"

​
query
object
required

The top-level object for querying traced calls.

The Query wraps a single $expr, which uses Mongo-style aggregation operators to filter calls. This expression can combine logical conditions, comparisons, type conversions, and string matching.

Examples: ``` # Filter calls where op_name == "predict" { "$expr": { "$eq": [ {"$getField": "op_name"}, {"$literal": "predict"} ] } }

# Filter where a call's display name contains "llm"
{
    "$expr": {
        "$contains": {
            "input": {"$getField": "display_name"},
            "substr": {"$literal": "llm"},
            "case_insensitive": true
        }
    }
}
```
