## 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
## Farcaster Casts Scraper: Posts, Authors & Engagement
> Collect casts (posts) from Farcaster, the decentralized social network. Pull a user's casts by username or FID, or search casts by keyword, and get each cast with its full text, timestamp, author profile (username, display name, follower count, bio and avatar) and engagement metrics (replies, reactions, recasts, quotes and views), plus images, embedded links and a Warpcast URL. Export clean structured data for social listening, web3 research, community analytics and lead discovery.

### What you get
For each cast:
- **Content** - the cast text, timestamp, thread and parent hashes, and whether it is a reply.
- **Author** - FID, username, display name, follower and following counts, bio and avatar URL.
- **Engagement** - replies, reactions (likes), recasts, quotes, watches, views and combined recasts.
- **Media** - image count and first image, embedded link count and first link.
- **Links** - a ready-to-open Warpcast URL for every cast.
### Who is it for
| Use case | Who benefits |
|---|---|
| Social listening | Teams tracking mentions of a brand, token or topic on Farcaster |
| Web3 research | Analysts studying crypto and builder conversations |
| Community analytics | Founders measuring reach and engagement of key accounts |
| Lead discovery | Growth teams finding active, high-follower authors on a topic |
### How to use it
1. Add one or more **usernames** (or **FIDs**) to pull their casts, and/or **search keywords** to find matching casts.
2. Optionally exclude replies or set a **minimum reactions** threshold.
3. Set **Max Casts To Scrape** and run. Export as JSON, CSV or Excel, or pull it through the Apify API.
You are only charged for casts actually returned. Runs that match nothing cost nothing.
### Frequently Asked Questions
**What is a cast?**
A cast is a post on Farcaster, similar to a tweet. Each cast has an author, text, timestamp and engagement counts.
**Can I track a topic across the network?**
Yes. Use the search keywords to collect every matching cast, with the author and engagement for each.
**Can I pull several accounts at once?**
Yes. Add several usernames or FIDs and each account's casts are collected in the same run.
**How fresh is the data?**
Casts are read live at run time, so each record reflects Farcaster at the moment of the run (see observedAt).
### Export, API and AI agents (x402 + MCP)
Export the scraped data to **JSON, CSV or Excel**, pull it as a **dataset** through the Apify **API**, or wire it into your app with **no code**. This web scraper and data extractor also works for bulk data extraction and scheduled runs.
For AI agents: this Actor is available on **x402**, Apify's agentic payment standard built with Coinbase. An AI agent can discover, pay for and run it on its own with a funded wallet and a single HTTP request: no account, no subscription, no API key and no human in the loop. It also runs as an **MCP** tool inside Claude, Cursor and other AI clients out of the box. Learn more about [x402 agentic payments on Apify](https://docs.apify.com/platform/integrations/x402).
