## What's an Apify Actor?
Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.
In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):
```bash
npm install apify-client
```
In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):
```bash
pip install apify-client
```
In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):
````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash
In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).
If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).
For usage examples, see the [API](#api) section below.
For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).
# README

## 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.
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).
