## 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

## ERC-20 Token Holder Distribution Tracker

> Returns the **top N holders of any Ethereum ERC-20 token**, with balance, share %, top-10/top-100 concentration, and total holder count. Powered by Ethplorer's free API — no key required.

***

### ⚡ Run in 30 seconds

Click **Start** with default settings — returns the top 100 holders of the sample ERC-20 token with each holder's balance, percentage share, and concentration metrics showing how much of the supply the top-10 and top-100 addresses control. No API key needed.

***

### What It Does

For any ERC-20 contract address you provide, this Actor returns:

- **Top N holders** (default 50, max 1000) with `address`, `balance`, `share_pct`
- **Total holders count**
- **Top-10 / Top-100 concentration %** (how much of supply is held by the largest wallets)
- **Total supply** (native units)

Useful for whale detection, distribution event verification, pre-trade due diligence, and dilution monitoring.

***

### Why This Matters

- **Whale concentration shifts predict moves.** When top-10 share drops 3% in a day, that's heavy distribution being absorbed by smaller wallets — often after exchange listings or unlocks.
- **Pre-trade DD** — a "fair launch" memecoin where top-10 hold 60% is a rug-pull risk. Surfaces this in one API call.
- **Dilution tracking** — for governance tokens, compare top-100 share month over month to spot DAO selling.

***

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `tokens` | array of strings | — | ERC-20 contract addresses (required) |
| `topN` | integer | `50` | Holders per token (5–1000) |
| `minSharePct` | number | `0` | Skip holders below this % |
| `ethplorerApiKey` | string (secret) | `freekey` | Optional paid Ethplorer key for higher limits |

#### Example: PEPE whale watch

```json
{
  "tokens": ["0x6982508145454ce325ddbe47a25d4ec3d2311933"],
  "topN": 100,
  "minSharePct": 0.5
}
```

#### Example: Multi-token concentration sweep

```json
{
  "tokens": [
    "0x6982508145454ce325ddbe47a25d4ec3d2311933",
    "0x95aD61b0a150d79219dCF64E1E6Cc01f0B64C4cE",
    "0x4d224452801ACEd8B2F0aebE155379bb5D594381"
  ],
  "topN": 20
}
```

### Output

Per holder row:

```json
{
  "token_symbol": "PEPE",
  "token_name": "Pepe",
  "token_address": "0x6982508145454ce325ddbe47a25d4ec3d2311933",
  "rank": 1,
  "holder_address": "0xf977814e90da44bfa03b6295a0616a897441acec",
  "balance": 56116400786424057000000.0,
  "share_pct": 13.34,
  "is_contract": null
}
```

Plus a per-token **SUMMARY**:

```json
{
  "token_symbol": "PEPE",
  "total_holders": 555833,
  "top_10_share_pct": 51.42,
  "top_100_share_pct": 73.18,
  "holders_returned": 100
}
```

***

### Pricing

- **$0.001 per holder row returned**

Examples:

- Top 50 for one token: **$0.05**
- Top 100 for 5 tokens: **$0.50**

***

### Use Cases

**Whale concentration alarm** — Run daily for tokens you hold, alert when `top_10_share_pct` rises >2% day-over-day (= whale accumulation).

**Memecoin DD bot** — Before any memecoin trade, query holders and reject if `top_10_share_pct > 50`.

**DAO health monitor** — Track governance token concentration over time. Healthy DAOs see top-100 share drift down.

***

### Data Source

- **Ethplorer** `/getTokenInfo` + `/getTopTokenHolders` — uses the public `freekey` by default. Pass your own Ethplorer API key for higher rate limits.

***

### Limitations

- Ethereum mainnet only.
- Free Ethplorer tier has rate limits — large batches may hit them. Provide your own API key for production scale.
- `is_contract` is not reliably populated by the free API.

# Actor input Schema

## `tokens` (type: `array`):

ERC-20 contract addresses to query. Each address consumes one query.

## `topN` (type: `integer`):

Number of top holders to fetch per token (max 1000 due to Ethplorer free tier).

## `minSharePct` (type: `number`):

Skip holders whose share is below this %. 0 = include all.

## `ethplorerApiKey` (type: `string`):

Bring your own Ethplorer API key for higher rate limits. Leave empty to use the free shared key (slower).
