## 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`).

### Input fields

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `text` | string | ✅ | Plain text to synthesize, 1–2,000 Unicode code points. Billing counts code points in started blocks of 1,000 ($0.01 per block, minimum one block). |
| `voice` | select | ❌ | Fixed to `en_GB-jarvis-high`. No cloning, no alternative voices, no model selectors. |
| `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.

3. **Run** — the actor returns a signed HTTPS download URL (valid 24 hours), audio metadata and billing details in the Output tab and dataset.

| 1,001–2,000 | 2 | $0.02 |
| 1,000,000 | 1,000 | **$10.00** |

One price covers speech synthesis, Apify platform usage, storage and audio delivery. Blocks are charged only for a successfully delivered, non-empty clip; failed runs cost $0.

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config.
