## 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.

### 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: D1 — Official/public-data actor
- Primary event: `record-fetched` at $0.00908 base
- Default max charge: $15.00
- Store discounts: FREE/BRONZE base, SILVER discounted, GOLD deepest approved discount

Event set:

- `actor-start`: base $0.02000, GOLD $0.01760. Open Data Ckan Inventory: charged when actor start is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `record-fetched`: base $0.00908, GOLD $0.00799. Open Data Ckan Inventory: charged when record fetched is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `event-detected`: base $0.01300, GOLD $0.01140. Open Data Ckan Inventory: charged when event detected is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `report-generated`: base $0.05000, GOLD $0.04400. Open Data Ckan Inventory: charged when report generated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.

The actor accepts `actor-start` before work, accepts the primary event before each dataset row, and accepts the configured report event before writing report files. If `maxChargeUsd` or the live PPE limit blocks a charge, the corresponding row or report is not written.

### Public Task Concepts

- Inventory permit datasets
- Export air quality resource metadata
- Build a housing data catalog
- List transportation packages without resources
- Inventory public water quality resources

### Inputs

- `portalUrls`
- `query`
- `organizations`
- `groups`
- `resourceFormats`
- `maxPackages`
- `includeResources`
- `includeSchemaHints`
- `sampleCsvHeaders`
- `checkResourceAvailability`
- `requestDelayMs`
- `timeoutMs`

The exact default queries the public data.gov.uk CKAN API for two planning-permission packages, verified at 2026-07-12T06:15:00Z.

### Outputs

- `packageId`
- `packageName`
- `packageTitle`
- `organization`
- `groups`

## CLI example

```bash
echo '{}' |
apify call junipr/open-data-ckan-inventory --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,junipr/open-data-ckan-inventory"
        }
    }
}

```

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).
