Evaluators

Run evaluators over a voice call

Changed on

VOICE RUN: Execute evaluators against your agent using a real voice / phone / SIP call. This is the primary 'run your evaluators' endpoint for voice-mode testing. Requires telephony.phone_number configured on the agent (any provider).

Run-count math: total calls = len(scenarios) × frequency × max(1, len(personality_ids)) × max(1, len(test_profile_ids)). Each call is billed at the voice-simulation rate — check frequency carefully.

Concurrency: use concurrency_limit to cap parallel calls. Default: unbounded (subject to provider rate limits).

Scenario selection (pick one):

  • scenarios — list of integer evaluator IDs (e.g. [101, 102])
  • tags — select by tag
  • folder_path — select by folder path (e.g. "Sales.Inbound"); requires project_id

Phone-number overrides:

  • outbound_phone_number — override the number dialed
  • agent_number — override the contact number the inbound agent receives calls on
  • mode — same_number (all runs use one pair) vs different_numbers

When to use this vs others (pick the endpoint matching the agent's configured connection — check aiagents_retrieve):

  • run_scenarios_text — text / SMS / chat mode; cheaper, no voice cost
  • run_scenarios_with_websockets — each scenario carries its own websocket URL
  • run_scenarios_pipecat — Pipecat/Daily.co WebRTC deployment

Personality override: personality_ids must be IDs that are already enabled for the agent's project. Check which are enabled via aiagents_retrieve → enabled_personalities field. To enable a new personality, call aiagents_partial_update with the updated enabled_personalities list before using it here. Note: enabling a personality applies project-wide, not just to one agent. Passing an ID that is not enabled returns ["Invalid personalities provided."].

Scheduled runs: to run on a recurring cron schedule, create a CronJob via POST /test_framework/v1/cron_jobs/ with execution_mode="voice" instead of looping this endpoint.

Polling for completion: the response is the result itself — read its top-level id (status: 'running'). Poll GET /test_framework/v1/results/{result_id}/ until status is completed, failed, timeout or cancelled. A result stays non-terminal until every run has ended, then becomes completed if any run completed — even if runs failed their checks or others errored. To gate, require success_runs_count == total_runs_count (failed_runs_count counts only completed runs that failed evaluation). There is no separate progress endpoint for runs. Check failed_reasons for infrastructure errors; check runs[run_id].error_message for per-run errors.

Outbound dial window: for outbound runs (agent inbound=false), your agent must dial the run's outbound_number before outbound_dial_window_closes_at (default 300s after the run reaches waiting_for_call / pending state). Dials received after that deadline are dropped and the run returns status: timeout.

Request body

agent_idinteger

ID of the agent to run evaluators for

assistant_idstring

Alternative to agent ID - the assistant ID to use for this scenario Example: "asst_1234567890"

scenariosinteger[]

List of evaluator IDs to run. Either scenarios, tags, or folder_path must be provided. Runs start in the order given. Example: [11, 22, 33]

To run evaluators by tag or folder, use the tags or folder_path fields instead.

tagsstring[]

List of tags to filter evaluators to run. Either evaluators or tags must be provided. Example: ["tag1", "tag2", "tag3"]

folder_pathstring

Dot-separated folder path to select evaluators from (e.g. "Sales.Inbound"). Mutually exclusive with scenarios and tags. Requires project_id.

project_idinteger

Project ID. Required when using folder_path (or when passing a folder path string via scenarios). Example: 1376

frequencyinteger

The number of times each evaluator will run. Each repeat runs the whole list in order before the next one starts (A, B, A, B), rather than grouping repeats of one evaluator. Example: 1

namestring

Label text for result

outbound_phone_numberstring

Override the phone number to use for outbound calls. Example: "+1234567890"

personality_idsinteger[] nullable

List of personality IDs to override for this run. If not provided, uses the scenario's default personality. Example: [123, 456, 789]

test_profile_idsinteger[] nullable

List of test profile IDs to override for this run. If not provided, uses the scenario's default test profile. Example: [123, 456, 789]

personality_idinteger nullable

Single personality ID override. Merged into personality_ids; prefer personality_ids for multiple.

test_profile_idinteger nullable

Single test profile ID override. Merged into test_profile_ids; prefer test_profile_ids for multiple.

mode'same_number' | 'different_numbers'

Using same or different phone numbers for each evaluation

  • same_number - same_number
  • different_numbers - different_numbers
agent_numberstring

Override the phone number from which the agent under test receives the call during outbound runs. This allows overriding the default agent contact number for testing purposes. Example: "+1234567890"

concurrency_limitinteger

Cap on the number of evaluator runs executed in parallel. Default: unbounded (subject to your provider's rate limits). Use this to avoid hitting provider rate limits on large frequency or folder runs. Example: 5

calls_per_secondnumber double nullable

Most calls started per second for this run, a number from 0.1 to 4 (e.g. 0.5 starts one call every 2 seconds). Leave unset for no limit.

mock_tool_namesstring[]

Names of mock tools to activate for this run. Cekura swaps those tools' URLs to mock endpoints while the run is active and restores the originals when it finishes. Omit (or send null) to mock every tool configured on the agent; send an empty list to mock none so every tool keeps its original endpoint. Example: ["get_appointments", "cancel_booking"]

agent_version_idstring

Run against a stored version of the agent instead of the agent as it is live. Cekura makes a private copy of the agent in your provider account, puts that version's prompt on it, and runs against the copy — voice, model and tools stay as the agent is configured now, and the live agent is never changed. Accepts the version label shown in the agent's version history (v12, or p1 for a version an improvement run proposed) or its numeric history_id. List them with GET /test_framework/v1/aiagents/{id}/history/; a version is usable when its is_runnable is true. Available for VAPI, Retell, ElevenLabs and Bland agents that are outbound and have a single prompt. Example: "v12"

Response

idinteger

ID of the result

agentinteger

ID of the agent

status'running' | 'completed' | 'failed' | 'pending' | 'in_progress' | 'evaluating' | 'in_queue' | 'timeout' | 'cancelled' | 'scaling_up'

Status of the result. Poll until it is completed, failed, timeout or cancelled. It stays non-terminal until every run has ended, then becomes completed if any run completed — even if runs failed their checks or others errored.

run_as_textboolean

Whether the scenario ran as text or not

created_atstring date-time
