## Response

### 200

Successful Response

- `data` (list of AgentResponse, required)
- `total` (integer, required)

## Errors

### 422 Unprocessable Entity Error

Validation Error

- `detail` (list of ValidationError, optional)

## Types

### AgentResponse

- `id` (string, required)
- `name` (string, required)
- `description` (string, required, nullable)
- `voiceMode` (enum, required)
  - Allowed values: `webhook`, `hosted`
- `voice` (string, required)
- `createdAt` (datetime, required)
- `enableMessaging` (boolean, optional, default: true)
- `modelTier` (enum, optional, default: balanced)
  - Allowed values: `turbo`, `balanced`, `max`
- `systemPrompt` (string, optional, nullable)
- `beginMessage` (string, optional, nullable)
- `transferNumber` (string, optional, nullable)
- `customTools` (list of AgentResponseCustomToolsItems, optional, nullable)
- `voicemailMessage` (string, optional, nullable)
- `callScreeningIdentity` (string, optional, nullable)
- `callScreeningPurpose` (string, optional, nullable)
- `sttMode` (enum, optional, default: fast) — Speech-to-text mode. 'fast' optimizes for latency, 'accurate' optimizes for transcription accuracy (~200ms additional latency).
  - Allowed values: `fast`, `accurate`
- `ambientSound` (enum, optional, default: none) — Background ambience to mask synthetic silence between turns. 'none' disables; 'office', 'coffee-shop', 'outdoor' enable a quiet bed.
  - Allowed values: `none`, `office`, `coffee-shop`, `outdoor`
- `denoisingMode` (enum, optional, default: noise-cancellation) — Audio denoising. 'noise-cancellation' (default) handles general noise. 'noise-and-background-speech-cancellation' is more aggressive for callers in cars, cafes, or near TVs.
  - Allowed values: `noise-cancellation`, `noise-and-background-speech-cancellation`
- `maxSilenceMs` (integer, optional, default: 600000) — Hang up the call after this many milliseconds of caller silence. Range 10000 (10s) to 3600000 (1 hour). Default 600000 (10 min).
- `voiceSpeed` (double, optional, default: 1) — Voice speed multiplier. Range 0.5 to 2.0. Default 1.0.
- `interruptionSensitivity` (double, optional, default: 0.8) — How easily callers can interrupt the agent. Range 0.0 to 1.0. Default 0.8.
- `enableBackchannel` (boolean, optional, default: true) — When true, the agent interjects short filler words like 'uh-huh' or 'mhmm' during longer caller utterances. Defaults to true.
- `language` (string, optional, default: en-US) — BCP-47 locale that drives the agent's speech recognition and pronunciation. Defaults to 'en-US'.
- `numbers` (list of AgentNumberResponse, optional, nullable)

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
- `type` (string, required)

### AgentResponseCustomToolsItems

### AgentNumberResponse

- `id` (string, required)
- `phoneNumber` (string, required)
- `status` (string, required)
- `type` (string, optional, default: sms)

### ValidationErrorLocItems
