## 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.

# README

## HTML Validity Report Generator

Generate a deterministic validity report for HTML with structured findings and source locations (line/column) suitable for CI pipelines, QA checks, and compliance-style audits.

This Actor performs standards-oriented structural and semantic checks and emits a stable, machine-readable report. It is designed for **authority and repeatability**, not interpretation.

***

### What This Actor Does

- Parses HTML deterministically and produces a validity report
- Reports findings with severity and fix guidance
- Includes location tracking (line/column) when available
- Supports `web` and `email` validation modes
- Outputs one dataset item per run

***

### Input

- **preset**: `none` | `broken-html-v0.1` | `clean-html-v0.1`
- **html**: raw HTML input (required if preset is `none`)
- **url**: optional URL to fetch HTML from (public pages only)
- **mode**: `web` or `email`
- **maxFindings**: cap findings count (default 200)
- **strict**: FAIL if any critical findings exist (default true)

***

### Output

The Actor writes a single dataset item containing:

- `verdict`: PASS | FAIL
- `score`: 0–100 deterministic validity score
- `counts`: critical/major/minor totals
- `findings`: structured list with ids, messages, fixes, and locations
- `metadata`: version, mode, hash, timestamp

All runs are deterministic for a given input.

***

### What This Actor Does NOT Do

- No LLM enrichment
- No paywall/login access
- No dynamic rendering
- No automatic rewriting of your HTML

***

### Legal & Compliance

- Processes only provided HTML or publicly accessible URLs
- No personal data intentionally stored
- Deterministic and audit-friendly by design

***

### Versioning

- v0.1 — initial authority-grade rule set + location-aware findings

# Actor input Schema

## `preset` (type: `string`):

Optional built-in presets for validation

## `html` (type: `string`):

Raw HTML to validate. Required when preset is 'none'.

## `url` (type: `string`):

If provided, the Actor will fetch HTML from this URL (public pages only).

## `mode` (type: `string`):

web = general HTML checks; email = stricter email-safe checks (table layout, inline CSS expectations).

## `maxFindings` (type: `integer`):

Maximum number of findings recorded before stopping.

## `strict` (type: `boolean`):

If enabled, verdict FAIL when any critical findings exist.

## Actor input object example

```json
{
  "preset": "none",
  "html": "",
  "url": "",
  "mode": "web",
  "maxFindings": 200,
  "strict": true
}

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("tempting_district/html-validity-report-generator").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("tempting_district/html-validity-report-generator").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call tempting_district/html-validity-report-generator --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,tempting_district/html-validity-report-generator"
        }
    }
}

```

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).
