## 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.

## RSS Feed Validator

### Store Positioning

**Store title:** RSS Feed Validator

**Short description:** Validate RSS and Atom feeds for feed-level health, required channel/feed fields, item metadata, GUID/link/date quality, duplicate entries, enclosure issues, HTTP status, content type, and caching headers.

**SEO title:** RSS Feed Validator — data QA, validation, and cleanup utility

**SEO description:** Validate RSS and Atom feeds for feed-level health, required channel/feed fields, item metadata, GUID/link/date quality, duplicate entries, enclosure issues, HTTP status, content type, and caching headers. Use it to validate rows, schemas, duplicates, field quality, and delivery-readiness before handing data to clients or automations.

### Pay-Per-Event Pricing

This actor uses pay-per-event pricing. Event prices include Apify platform usage; users are not expected to pay a separate platform-usage pass-through charge for the configured pricing model.

- Tier: U2 — Data/schema QA utility
- Primary event: `record-profiled` at $0.00390 base
- Default max charge: $5.00
- Store discounts: FREE/BRONZE base, SILVER discounted, GOLD deepest approved discount

Event set:

- `actor-start`: base $0.00500, GOLD $0.00400. RSS Feed Validator: charged when actor start is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `record-profiled`: base $0.00390, GOLD $0.00312. RSS Feed Validator: charged when record profiled is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `issue-detected`: base $0.00372, GOLD $0.00298. RSS Feed Validator: charged when issue detected is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `qa-report-generated`: base $0.05000, GOLD $0.04000. RSS Feed Validator: charged when qa report generated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.

### Public Task Concepts

- Validate RSS Feed records from a capped sample
- Find invalid RSS Feed values before delivery
- Check RSS Feed coverage against expected rules
- Prioritize RSS Feed validation failures by severity
- Export RSS Feed pass-fail rows with evidence

Validates RSS 2.0 and Atom feed health at feed and item level, including title/link presence, GUID/ID quality, dates, duplicates, enclosures, and feed type.

### Inputs

- `feedUrls`
- `rawFeedXmlInputs`
- `headers`
- `requireGuidOrId`
- `requireItemDates`
- `requireItemLinks`
- `checkDuplicateItems`
- `checkEnclosures`
- `includeHttpHeaders`
- `maxItemsPerFeed`
- `requestDelayMs`
- `timeoutMs`
- `maxChargeUsd`

### Public source provenance

The starter input uses https://www.nasa.gov/feed/ (bounded public NASA RSS snapshot). The checked-in bounded snapshot keeps exact runs deterministic and avoids sending credentials or private data. Live URL inputs remain available when a current network check is required.

### Outputs

Dataset fields: `feedUrl`, `feedType`, `feedTitle`, `feedLink`, `itemIndex`, `itemId`, `itemTitle`, `itemLink`, `publishedAt`, `updatedAt`, `enclosureUrl`, `httpStatus`, `contentType`, `issueCode`, `severity`, `duplicateGroupId`, `recommendation`, `passed`.

Reports: `rss-feed-validation-report.md`, `rss-feed-issues.csv`, `rss-feed-health-summary.json`, `duplicate-feed-items.json`, `enclosure-check-results.csv`.

Use small capped runs first; live network checks should stay bounded and avoid secrets in inputs.

Live and local execution use the same pay-per-event billing guard: the actor-start event is accepted before analysis, each paid row is charged before dataset output, reports are charged before key-value-store output, and `maxChargeUsd` stops gracefully without leaking unpaid artifacts.

# Actor input Schema

## `feedUrls` (type: `array`):

Public feed URLs to fetch or inspect for RSS Feed Validator.

## `rawFeedXmlInputs` (type: `array`):

Optional supplied feed XML documents to parse without fetching remote URLs.

## `headers` (type: `object`):

Optional request headers for authorized endpoints. Avoid secrets in shared examples and public tasks.

## `requireGuidOrId` (type: `boolean`):

Require guid or ID during validation and flag rows that do not meet the rule.

## `requireItemDates` (type: `boolean`):

Require item dates during validation and flag rows that do not meet the rule.

## `requireItemLinks` (type: `boolean`):

Require item links during validation and flag rows that do not meet the rule.

## `checkDuplicateItems` (type: `boolean`):

Check duplicate items and emit findings when the condition is not met.

## `checkEnclosures` (type: `boolean`):

Check enclosures and emit findings when the condition is not met.

## `includeHttpHeaders` (type: `boolean`):

Include http headers in output rows or reports when available.

## `maxItemsPerFeed` (type: `number`):

Maximum items per feed to process in one run; keep defaults low for safe first runs.

## `requestDelayMs` (type: `number`):

Request Delay ms controls RSS Feed Validator processing for the supplied inputs; keep values conservative for first runs.

## `timeoutMs` (type: `number`):

Maximum time in milliseconds allowed for the RSS Feed Validator operation before it is treated as timed out.

## `maxChargeUsd` (type: `number`):

Maximum estimated PPE charge allowed for the run before the actor stops gracefully.

# 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("junipr/rss-feed-validator").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);
});

## CLI example

```bash
echo '{}' |
apify call junipr/rss-feed-validator --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,junipr/rss-feed-validator"
        }
    }
}

```

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).
