## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

### 🧾 JSON sample record

One real record from run `mAbfk0PbjmXN2ZGdn` (emails/phones masked, long text shortened):

```json
{
  "board": "newsplus",
  "thread_id": "9240230830",
  "title": "★ UPLIFT プレミアム・サービスのお知らせ",
  "post_count": 2,
  "thread_url": "https://asahi.5ch.io/test/read.cgi/newsplus/9240230830/",
  "last_active": "2262-10-24T02:47:10Z",
  "data_source": "asahi.5ch.io/newsplus/subject.txt",
  "as_of_timestamp": "2026-09-25T03:20:48Z"
}
```

### 💰 Pricing

| Event | Price (USD) | When it is charged |
|---|---|---|
| Actor Start (`apify-actor-start`) | $0.005 | Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event). |
| Thread post (`apify-default-dataset-item`) | $0.1 | Charged per record extracted into your dataset. |

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.1 = $10.00 plus the start fee.

# Actor input Schema

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

What to collect. 'board-threads' = list the active thread list for a board (titles + post counts + URLs) from subject.txt — best for trend / buzz monitoring. 'thread-posts' = read every post in one thread (supply threadUrl) — best for sentiment, RAG corpora and full-text mining. 'search' = list a board's threads then keep only those whose title contains your keyword.

## `board` (type: `string`):

5ch board slug to read (used by board-threads and search). Examples: 'newsplus' (ニュース速報+, the main news board), 'news4vip' (ニュー速VIP), 'mnewsplus' (芸スポ速報+ / entertainment & sports), 'seijinewsplus' (政治ニュース+ / politics). The actor resolves the board's server automatically from the live 5ch board directory (bbsmenu).

## `threadUrl` (type: `string`):

Full 5ch thread URL to read posts from, e.g. https://asahi.5ch.net/test/read.cgi/newsplus/1781497598/ . Required when mode='thread-posts'. You can get these URLs from a board-threads run (thread_url field).

## `keyword` (type: `string`):

When mode='search', keep only threads whose title contains this string (case-insensitive substring match). Japanese or English. Ignored in other modes.

## `maxItems` (type: `integer`):

Hard cap on records returned per run. In board-threads/search mode each record is a thread; in thread-posts mode each record is a single post. 15-50 is typical for monitoring; a busy thread can have 1000+ posts.

## `proxyConfiguration` (type: `object`):

Apify proxy. 5ch is open over plain HTTP, so the default datacenter Apify Proxy is fine. Add a Japan-egress / residential group if you hit occasional rate-limiting on heavy runs.

## `notionConnector` (type: `string`):

Optional. Connect your Notion workspace and the results are also written as a Notion page in the same run — the Actor never sees your Notion credentials. Authorize a Notion MCP connector in Apify Console → Settings → API & Integrations, then select it here.

## `notionParentId` (type: `string`):

Optional. The Notion page ID to create the page under. If blank, Notion creates a private page in your workspace.

## `supabaseConnector` (type: `string`):

Optional. Connect your own Supabase project and the results are also inserted into a table in the same run — the Actor never sees your Supabase credentials. Authorize a write-scoped, project-scoped Supabase MCP connector in Apify Console (Settings -> Integrations), then select it here.

## `supabaseTable` (type: `string`):

Target table in the public schema (created if missing, with id, a jsonb data column, and a scraped_at timestamp). Default: nexgendata_leads.

## `supabaseProjectId` (type: `string`):

Your Supabase project reference (e.g. abcdefghijklmnop). Required unless your connector URL is already project-scoped. Find it in your project URL: supabase.com/dashboard/project/THIS_PART.

## `deliveryDedup` (type: `boolean`):

When on (default), records already delivered in a previous run are not delivered again to the same destination — so scheduled runs only push new items. Turn off to deliver every record on every run.

## Actor input object example

```json
{
  "mode": "board-threads",
  "board": "newsplus",
  "maxItems": 50,
  "proxyConfiguration": {
    "useApifyProxy": true
  },
  "supabaseTable": "nexgendata_leads",
  "deliveryDedup": true
}
```

# Actor output Schema

# 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.

## CLI example

```bash
echo '{
  "mode": "board-threads",
  "board": "newsplus",
  "maxItems": 50,
  "proxyConfiguration": {
    "useApifyProxy": true

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,nexgendata/5ch-thread-tracker"
        }
    }
}
```

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).
