## 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

## Newsletter Sponsor Finder

Find newsletter sponsors and ad placements from public archives.

### Why use this Actor?

Extract sponsor names, offers, and links from public newsletter archive and article pages.

It is built for clean marketplace-ready output: no huge raw HTML dumps, no noisy nested records, and no confusing fields. Each result is a compact business signal that can go directly into a spreadsheet, Airtable, CRM, or monitoring workflow.

### Best for

- Find brands buying newsletter ads
- Research sponsorship offers
- Build sponsor prospect lists

### Input

The input is intentionally simple:

- `startUrls` - public pages to analyze
- `maxPagesPerStartUrl` - how many same-domain pages to inspect
- `maxResultsPerPage` - maximum clean results saved from each page
- `includeEvidence` - save a short evidence snippet
- `proxyConfiguration` - optional Apify proxy settings

#### Example input

```json
{
  "startUrls": [
        {
            "url": "https://www.morningbrew.com/advertise"
        },
        {
            "url": "https://www.tldrnewsletter.com/advertise"
        }
  ],
  "maxPagesPerStartUrl": 2,
  "maxResultsPerPage": 10,
  "includeEvidence": true
}
```

### Output

Each dataset item contains only useful fields:

- `name`
- `summary`
- `category`
- `matchedSignals`
- `priceOrValue`
- `date`
- `score`
- `domain`
- `resultUrl`
- `pageUrl`
- `errorMessage`

#### Example output

```json
{
  "status": "ok",
  "name": "Example matched result",
  "summary": "A short useful sentence explaining the relevant finding.",
  "category": "pricing",
  "matchedSignals": [
    "sponsor",
    "sponsored",
    "partner"
  ],
  "priceOrValue": "$29/month",
  "date": "2026-07-09",
  "score": 51,
  "domain": "morningbrew.com",
  "resultUrl": "https://www.morningbrew.com/advertise",
  "pageUrl": "https://www.morningbrew.com/advertise",
  "errorMessage": null
}
```

### Pricing

Recommended monetization is pay per saved result at **$0.0030 per result**.

Users also pay normal Apify platform usage costs, such as compute, storage, and proxy usage where applicable.

### Notes and limitations

- Works on public HTML pages.
- Login-only, CAPTCHA-heavy, and heavily blocked websites may need proxies or may fail.
- The Actor extracts public page signals; it does not access private accounts or restricted data.
- JavaScript-only pages may return fewer results because this lightweight version is optimized for speed and low compute cost.
