Headers

​
authorization
string
required
Your API key for authentication.

​
Body Parameters

​
call_ids
array of string
required
The call IDs to score. Between 1 and 5000 calls.
​
attached_agents
array of objects
The eval agents to score with. Maximum 50 agents. Each object:
​
run_mode
string
The scoring modality. One of text, audio, or full. Defaults to text.
​
pass_threshold_pct
number
Percentage of evaluations that must pass for the run to be marked passing overall, 0-100. Omit to run without a threshold.
​
workbench_setup_id
string
UUID of a workbench setup to associate with this run. Must be provided together with workbench_setup_version_id.
​
workbench_setup_version_id
string
UUID of the pinned workbench setup version. The version’s agent roster is used when attached_agents is omitted. Must be provided together with workbench_setup_id.
​
triggered_by
string
How this run was initiated. One of manual, auto, or backfill. Defaults to manual.
​
metadata
object
Key-value metadata to attach to the run. Keys and values must be strings.
You must supply either a non-empty attached_agents array or a workbench_setup_version_id (whose pinned roster supplies the agents). If you provide workbench_setup_id or workbench_setup_version_id, both fields are required together. A valid billing record must be on file before a run can start.

​

run_mode
string
The scoring modality for this run.
​
submitted_call_ids
array of string
The call IDs submitted for scoring.
