## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

### Who uses it

- **AI agent developers** giving assistants a spoken interface
- **Automation builders** on n8n, Zapier, Make and Windmill generating voice notifications, IVR prompts or podcast drafts

- **Accessibility teams** adding on-demand speech to reading flows

### Input fields

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `text` | string | ✅ | Plain text to synthesize, 1–2,000 Unicode code points. Billing counts code points including spaces and punctuation, in started blocks of 1,000 ($0.01 per block, minimum one block). |
| `voice` | select | ❌ | Official preset voice ID: `F1`–`F5` (female) or `M1`–`M5` (male). Defaults to `F1`. No voice cloning. |
| `language` | select | ❌ | One of the 31 supported Supertonic-3 languages. Defaults to `en`. |
| `speed` | number | ❌ | Speaking-rate multiplier, 0.7–1.5. Defaults to 1.05. |
| `acceptTerms` | boolean | ✅ | Must be `true`: you agree to disclose synthetic speech and not impersonate or mislead. |

### How to use

1. **Add your text** — paste or send 1–2,000 characters.
2. **Pick a voice** — try `F1` for a warm female narrator or `M2` for a calm male voice.
3. **Choose language and speed** — e.g. `tr` for Turkish at `1.0`.
4. **Accept the synthetic-speech terms** — set `acceptTerms: true`.
5. **Run** — the actor returns a signed HTTPS download URL (valid 24 hours), audio metadata and billing details in the Output tab and dataset.

#### Input example

```json
{
  "text": "Welcome to our service. This voice was generated by AI.",
  "voice": "F1",
  "language": "en",
  "speed": 1.05,
  "acceptTerms": true
}
```

### Output example

Real run output (abridged):

```json
{
  "ok": true,
  "kind": "tts",
  "voice": "F1",
  "language": "en",
  "charCount": 49,
  "duration": 4.2,
  "audioUrl": "https://minio.foxtools.de/...?X-Amz-Signature=...",
  "audioDelivery": "minio-presigned",
  "deliveryObjectKey": "foxo81/audio/....wav",
  "audioBytes": 370720,
  "audioSha256": "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855",
  "expiresAt": "2026-09-19T12:00:00Z",
  "billingUnit": "text-1k-chars",
  "billingQuantity": 49,
  "billingCount": 1,
  "billingPriceUsdPerBlock": 0.01,
  "totalChargeUsd": 0.01,
  "billingIsAllInclusive": true
}
```

### Pricing

**$0.01 per started 1,000 characters — all-inclusive.**

The math, shown plainly:

| Characters | Blocks (`ceil(chars/1000)`) | Cost |
| --- | --- | --- |
| 1–1,000 | 1 | $0.01 |
| 1,001–2,000 | 2 | $0.02 |
| 500,000 | 500 | $5.00 |
| 1,000,000 | 1,000 | **$10.00** |

That equals **$10 per 1M characters** — below most major cloud TTS APIs. One price covers speech synthesis, Apify platform usage, storage and audio delivery. No separate start fee, no usage surcharge. Blocks are charged only for a successfully delivered, non-empty clip; failed runs cost $0.

### Integrations and API

**Sync run (get dataset items directly):**

```bash
curl -X POST "https://api.apify.com/v2/acts/myagizm~supertonic-3-text-to-speech/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"text":"Hello from the API!","voice":"F1","language":"en","speed":1.05,"acceptTerms":true}'
```

**Async run:**

```bash
curl -X POST "https://api.apify.com/v2/acts/myagizm~supertonic-3-text-to-speech/runs?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"text":"Async speech generation.","acceptTerms":true}'
```

**n8n / Zapier / Make:** use the Apify node, pick this actor, map your text field to `text` and set `acceptTerms: true`.

### Tips

💡 Batch your scripts: 2,000 characters per run is the sweet spot — exactly 2 blocks.
💡 Download the WAV before `expiresAt` (24 h) if you need a permanent copy.
💡 Verify integrity with `audioSha256` after downloading.
💡 Use `speed: 0.9` for tutorials, `1.2` for energetic promos.

### FAQ

**Q: Which languages are supported?** English, Turkish, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Ukrainian, Russian, Arabic, Japanese, Korean, Bulgarian, Czech, Danish, Greek, Estonian, Finnish, Hindi, Croatian, Hungarian, Indonesian, Lithuanian, Latvian, Romanian, Slovak, Slovenian, Swedish, Vietnamese.

**Q: Can I clone a voice?** No. Only the ten official presets F1–F5 / M1–M5 are offered — this keeps output quality consistent.

**Q: What audio format do I get?** Uncompressed PCM WAV via a signed HTTPS download URL, valid for 24 hours.

**Q: Do failed runs cost money?** No. A block is charged only for a successfully delivered, non-empty clip.

**Q: Is the audio watermarked?** No watermark, but output is AI-generated and must be disclosed as such.

**Q: Why Unicode code points?** One emoji or non-Latin glyph counts as one code point, matching how models actually read text.

**Q: Can I use this commercially?** Yes — audiobooks, apps, ads — as long as you disclose synthetic speech and do not impersonate real people.

**Q: How fast is a run?** Typically a few seconds for short texts; the actor's internal deadline is 420 s.

**Q: Is there a free trial?** Apify's platform free tier gives you platform credits; per-event charges apply per delivered clip.

**Q: What about long documents?** Split them into ≤2,000-character chunks and run per chunk.

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
