## What's an Apify Actor?
Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".
## 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.
The best way to integrate Actors is as follows.
- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
For usage examples, see the [API](#api) section below.

## Tool: Image Description & Alt-Text Generator
> Turn any image URL into accessible alt text, a clear description, subject tags and any visible text. Built for accessibility, SEO and large image libraries.
**📥 [Input](https://apify.com/scrapers_lat/image-alt-text-tool/input-schema) · 📤 [Output](https://apify.com/scrapers_lat/image-alt-text-tool/output-schema) · 💰 [Pricing](https://apify.com/scrapers_lat/image-alt-text-tool/pricing) · ▶️ [Examples](https://apify.com/scrapers_lat/image-alt-text-tool/examples)**
Alt text under 125 characters
Description + tags scene, subjects, themes
JSON / CSV / Excel output formats
### What it does
Give it a list of public image URLs. For each image it returns a clean, structured record:
- **altText**: a concise, accessible alt text kept under 125 characters
- **description**: a fuller two to four sentence description of the scene and subjects
- **tags**: the main objects, subjects and themes in the image
- **detectedText**: any text that is legible in the image
- **imageUrl** and **observedAt** for every record
Use it to caption a whole media library, fill missing alt attributes for accessibility and SEO, or tag a product catalog. Export to JSON, CSV or Excel, or pull it through the Apify API.
### Paid plans only
This tool runs on the latest, most reliable premium AI models. Because each run has a real model cost, it is available to paid Apify accounts only. A run started from a free account stops immediately with an upgrade message. Upgrade your Apify subscription to a paid plan and run it again.
### Who is it for
| Use case | Who benefits |
|---|---|
| Accessibility | Teams adding alt text to meet WCAG requirements |
| SEO | Marketers captioning images for search and rankings |
| Ecommerce | Stores tagging and describing product photos at scale |
| Content ops | Publishers captioning large media libraries |
### Input
- **imageUrls**: a list of public image URLs to describe. Each image returns its own record.
### Notes
- The tool describes only what is visible in the image and does not invent details.
- Alt text is kept short and functional so it drops straight into an image tag.
- Provide direct links to the image files so they can be read reliably.

### Export, API and AI agents (x402 + MCP)
Export the scraped data to **JSON, CSV or Excel**, pull it as a **dataset** through the Apify **API**, or wire it into your app with **no code**. This web scraper and data extractor also works for bulk data extraction and scheduled runs.
For AI agents: this Actor is available on **x402**, Apify's agentic payment standard built with Coinbase. An AI agent can discover, pay for and run it on its own with a funded wallet and a single HTTP request: no account, no subscription, no API key and no human in the loop. It also runs as an **MCP** tool inside Claude, Cursor and other AI clients out of the box. Learn more about [x402 agentic payments on Apify](https://docs.apify.com/platform/integrations/x402).
