## 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`).

# README

## Schema Validator – Bulk Rich Results Test & Schema Checker

Check the schema markup (structured data) of hundreds of pages at once. For every page you get the schema types it has, which rich result types are valid and which have errors, every missing required and recommended property, broken JSON-LD blocks, and the SEO basics: title, meta description, canonical, meta robots and Open Graph tags.

Built for SEO audits of whole sites or product catalogues, checking a release or a template change before Google does, agencies reporting on clients, monitoring competitors' rich snippets, and AI agents that need to know whether a page is eligible for rich results.

### What you get

- **All three formats:** JSON-LD (including `@graph`), Microdata (nested items) and RDFa (counted).
- **Rich result rules** for Product, Recipe, FAQPage, Article (also NewsArticle and BlogPosting), BreadcrumbList, LocalBusiness (and its subtypes such as Restaurant or Dentist), Organization, Event, JobPosting, VideoObject, SoftwareApplication, Review, AggregateRating, Course, Dataset, Book, Movie, QAPage, ProfilePage and DiscussionForumPosting.
- **Errors** (missing required properties, offers without price, questions without answers, breadcrumbs without position, invalid JSON) and **warnings** (missing recommended properties such as image, brand, aggregateRating).
- **One row per page**, with every entity in `items`. The "Every entity" view gives one row per entity for spreadsheets.
- **SEO basics on every row:** title, meta description, canonical, meta robots, og:title, og:image.

### Example output row

A real recipe page (shortened):

```json
{
  "url": "https://www.bbcgoodfood.com/recipes/easy-chocolate-cake",
  "status_code": 200,
  "title": "Easy chocolate cake recipe | Good Food",
  "schema_types": ["BreadcrumbList", "Recipe", "VideoObject"],
  "rich_results_valid": ["BreadcrumbList", "Recipe", "VideoObject"],
  "rich_results_with_errors": [],
  "json_ld_items": 4,
  "microdata_items": 0,
  "errors": 0,
  "warnings": 3,
  "items": [
    {"type": "Recipe", "format": "json-ld", "rich_result": "Recipe", "valid": true, "errors": [], "warnings": ["missing aggregateRating (recommended)"]},
    {"type": "VideoObject", "format": "json-ld", "rich_result": "VideoObject", "valid": true, "errors": [], "warnings": ["missing description (recommended)"]}
  ]
}
```

### How to use

1. Click **Try for free** (or **Start**) at the top of this page to open the input form.
2. Fill in **Pages to check**. Page addresses, one per line, up to 2,000. The form comes with a working example, so you can also run it as it is.
3. Click **Start** and wait for the run to finish.
4. Download the results as Excel, CSV or JSON from the **Output** tab, or get them through the Apify API, a schedule or an integration (Make, Zapier, Google Sheets ...).

### Pricing

Pay per event, no subscription:

- **$0.50 per 1,000 pages** ($0.0005 per page checked).
- $0.001 per run start.

Examples: the pre-filled run (2 pages) costs $0.002. A 500-page product catalogue costs $0.251. Pages that cannot be fetched (errors, blocks, not HTML) are never charged.

### Input

| Field | What it does |
|---|---|
| `urls` | Page addresses, one per line, up to 2,000 per run. `example.com/page` works too. |

### Good to know

- **The page as served:** the Actor reads the HTML the server sends. Schema added later by JavaScript in the browser is not seen; most sites put JSON-LD in the HTML, and Google recommends that.
- **Rules follow Google's documented required and recommended properties.** Passing them makes a page eligible for rich results; Google still decides whether to show them.
- **Blocked sites:** some sites refuse automated visitors. They get an error row (not charged) instead of a guess.
- RDFa is counted, not validated.
- Not affiliated with Google or schema.org.

    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "urls": [

// Run the Actor and wait for it to finish
const run = await client.actor("rowfeed/schema-markup-validator").call(input);

// Fetch and print Actor results from the run's dataset (if any)

## MCP server setup

        }
    }
}
```

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).
