Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/voice/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get pricing plans

Get current Voice.ai pricing plans with features, credit limits, and audio tool file length limits. Plans are returned for the specified billing cycle. Each plan includes name, price, description, monthly credit allocation, file length limit, and marketing features. The pricing page is parsed from server-rendered content.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `billing_cycle` | string | No | Billing period. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/voice/get-pricing-plans \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"billing_cycle":"<string>"}'
```

### Get queue wait times

Get current estimated queue wait times (in seconds) for Voice.ai audio processing tools. Returns wait times for all tools by default, or for a specific tool when the tool parameter is provided. Tools include vocal-remover, echo-remover, demucs (stem splitter), audio-converter, and denoiser. Wait times are polled from the live queue and reflect real-time load.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `tool` | string | No | Filter to a specific audio tool. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/voice/get-queue-wait-times \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"tool":"<string>"}'
```

### List tts voices

List available text-to-speech demo voices from Voice.ai. Returns voice IDs, names, and avatar URLs for all predefined TTS voices available in the public demo. The maximum text length for the demo is also returned.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/voice/list-tts-voices \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
