## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## DeFi TVL Anomaly Detector

Scans 7,000+ DeFi protocols for extreme TVL changes in the last 24h. Detects hacks, rug pulls, suspicious inflows, and capital flight — before it shows up in the news.

### What It Does

Pulls the full DefiLlama protocol list and flags protocols with abnormal 24h TVL movement. Anomalies are classified by type and severity so you can triage at a glance.

### Anomaly Types

| Type | Severity | Description |
|---|---|---|
| `rug_or_drain` | **Critical** | TVL collapsed to near-zero from significant prior value |
| `severe_drain` | **High** | −70%+ TVL change in 24h (likely hack, exploit, or mass exit) |
| `major_drain` | **Medium** | −40%+ TVL change (significant capital flight) |
| `suspicious_spike` | **Medium** | +500%+ TVL spike (likely TVL manipulation or bootstrapped farming) |
| `major_inflow` | **Info** | +100%+ TVL growth (new incentive program, major partnership) |

### Input

| Field | Type | Default | Description |
|---|---|---|---|
| `minTvlMillion` | number | `0.1` | Min protocol TVL in $M to include. Filters dust/micro-protocols. |
| `minChangeAbsPct` | number | `40` | Min absolute 24h change % to report. |
| `severityFilter` | string | `""` | Filter to one severity: `critical`, `high`, `medium`, `info` |
| `sortBy` | string | `"severity"` | Sort: `severity`, `change_1d`, or `tvl` |
| `limit` | integer | `100` | Max results (up to 500) |

### Output Schema

```json
{
  "name": "Euler Finance",
  "slug": "euler",
  "category": "Lending",
  "chains": ["Ethereum"],
  "tvl_usd": 85000,
  "tvl_m": 0.085,
  "change_1d_pct": -98.5,
  "change_7d_pct": -97.2,
  "anomaly_type": "severe_drain",
  "severity": "high",
  "defillama_url": "https://defillama.com/protocol/euler",
  "fetched_at": "2026-07-08T14:00:00+00:00"
}
````

### Key Value Store

A `SUMMARY` object is saved with:

- `total_anomalies`: count of anomalies found
- `by_severity`: counts per severity level
- `by_type`: counts per anomaly type
- `critical_alerts`: top 10 critical findings
- `high_alerts`: top 10 high-severity findings

### Pricing

**$0.005 per run** — flat rate. No API key required.

### Use Cases

- **Security monitoring**: schedule every hour to catch exploits early
- **Risk management**: check exposure before entering large DeFi positions
- **Research signals**: large inflows often precede token price movements
- **Portfolio protection**: alert when protocols you use have anomalous TVL drops

### Data Source

DefiLlama free API (`api.llama.fi/protocols`) — public, no auth required.

### Notes

- TVL data is delayed ~1 hour from real-time blockchain state
- A "suspicious spike" is not necessarily malicious — it can be genuine growth from new farms
- `rug_or_drain` detection uses 7d TVL to estimate prior value; may fire on newly listed protocols
- For hacks specifically, cross-reference with Rekt.news or DeFiYield Shield

# Actor input Schema

## `minTvlMillion` (type: `number`):

Filter protocols with TVL below this threshold (in millions USD). Reduces noise from micro-protocols. Default: 0.1 ($100K).

## `minChangeAbsPct` (type: `number`):

Only include protocols with 24h TVL change greater than this absolute percentage. Default: 40 (40%).

## `severityFilter` (type: `string`):

Only return anomalies of this severity level. Leave empty to return all. Options: critical, high, medium, info.

## `sortBy` (type: `string`):

How to sort results. severity = most critical first. change\_1d = largest drain first. tvl = largest protocol first.

## `limit` (type: `integer`):

Maximum number of results to return. Default: 100, max: 500.

## Actor input object example

```json
{
  "minTvlMillion": 0.1,
  "minChangeAbsPct": 40,
  "severityFilter": "",
  "sortBy": "severity",
  "limit": 100
}
```

const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("gochujang/defi-tvl-anomaly-detector").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
