## 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.

- **Shipping and logistics** — Wave and marine conditions for coastal routes
- **Research** — Long historical climate datasets going back to 1940

### FAQs

**Is an API key required?**
No. Open-Meteo is free for non-commercial use with no registration required.

**How far back does historical data go?**
Historical data is available from 1940 onward for most locations.

**How accurate is the forecast?**
Open-Meteo uses multiple global weather models (ECMWF, GFS, etc.) and is highly accurate, especially for the first 7 days.

**Can I get hourly data?**
Yes — set `hourlyVars` to include variables like `temperature_2m`, `windspeed_10m`, etc.

**Why is marine data not available for my location?**
Marine data requires coordinates in or near ocean/coastal areas. Inland coordinates will return an error.

**What timezones are supported?**
Any IANA timezone string (e.g. `Europe/Berlin`, `America/New_York`). Use `auto` to detect from coordinates automatically.
