## 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

## Social Growth Monitor — IG/TikTok/YouTube (Vigia)

> Track Instagram, TikTok and YouTube profiles and get only what changed: follower moves, new posts, all-time-high follower alerts. Charged only on real changes, not per check. Ideal for influencer-marketing, creator-scouting and social-listening agents.

### Free tier — 10 results free on every run

**The first 10 results of every run are free**, on every run you ever make —
not a one-off trial. Run it on your own subjects and see the real output before
you are billed for a single result.

One guard: the free allowance never covers more than half of a run, so a run
returning 6 results gets 3 free. That keeps the offer sustainable.

### What it does

Monitor Instagram/TikTok/YouTube follower growth across accounts. You get **only what changed since your last check** — never a full re-dump to diff yourself.

### Why Vigia — 5 advantages a raw scraper can't match

1. **You pay the alert price only for real change.** New-follower change alerts are billed only for genuinely new follower changes since your last check. A quiet run bills just the small source-check fee (the cost of looking) — never the alert price on unchanged data. Raw scrapers bill every row of a full re-scan every run.
2. **Never billed on a failed source.** The source check is charged only when the source actually responded. If it's down, you don't pay for our outage.
3. **Append-only delta + spike signal.** The first monitored run stores a free baseline; later runs deliver only what's new, plus a velocity-spike alert when volume suddenly surges (trend / review-bomb / hiring-surge).
4. **Hard cost cap you control.** Set `maxTotalChargeUsd` and the run can never bill above it — predictable spend, no surprise invoice.
5. **Agent-ready output.** Clean, normalized rows and a `RUN_SUMMARY.json` with ready-to-use signals — chainable from any MCP / A2A agent in one step.

### Example input

```json
{
  "instagramUsernames": [
    "nike",
    "natgeo"
  ],
  "monitorEnabled": true,
  "maxTotalChargeUsd": 1.0
}
```

Set `monitorEnabled: true` so the first run stores a free baseline and later runs return only new results. Pin a `monitorId` to keep separate targets from sharing state.

### Output

Each row is a normalized change record: `record_id`, `change_type`, `platform`, `username`, `followers`, `previous_followers`, `follower_change`, `follower_growth_pct`, `at_all_time_high`. A `RUN_SUMMARY.json` accompanies every run with the aggregated signal (counts, velocity spikes, trend).

### How you're charged

- **Follower change alert** — billed once per new follower change since the last check (this is the only charge that scales with change).
- **Source check** ($0.12) — billed once per monitored target per run, **only when the source responded**. A failed source is free.
- **A quiet run bills only the source check** ($0.12), never the alert price. Vigia never scrapes the source itself; it chains a licensed scraper, caps every call, and passes you only the delta.

# Actor input Schema

## `instagramUsernames` (type: `array`):

Instagram usernames or profile URLs to track.

## `tiktokUsernames` (type: `array`):

TikTok usernames or profile URLs to track.

## `youtubeUsernames` (type: `array`):

YouTube channel handles (without @) or URLs to track.

## `currentProfiles` (type: `array`):

Bring your own normalized profile records instead of Vigia fetching them.

## `monitorEnabled` (type: `boolean`):

The first monitored run stores a free baseline. Later runs deliver and charge only changes.

## `monitorId` (type: `string`):

Pins the persistent baseline to a name of your choice. Leave empty to derive it automatically.

## `maxTotalChargeUsd` (type: `number`):

Hard maximum amount that this run's own change events may charge. Does not cap the separate cost of the chained Instagram/TikTok scraper calls.

## `sources` (type: `array`):

Declare every upstream source before this run.
