## 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.

- **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

## Stablecoin Supply Monitor — Minting, Burning & Depeg Detection

Track 400+ stablecoins using the [DefiLlama](https://defillama.com) public API. Monitor supply changes, detect minting/burning events, and flag depeg risks. No API key required.

### What it returns

| Field | Description |
|-------|-------------|
| `symbol` | Stablecoin ticker (USDT, USDC, DAI, etc.) |
| `name` | Full name |
| `circulating_usd` | Current circulating supply in USD |
| `change_24h_pct` | 24h supply change % (positive = minting) |
| `change_7d_pct` | 7-day supply change % |
| `peg_deviation_bps` | Price deviation from $1.00 in basis points |
| `is_depegged` | True if deviation > depeg threshold |
| `mechanism` | fiat / crypto / algorithmic / hybrid |
| `chains` | Chains where the stablecoin is deployed |

### Use cases

- Alert on large USDT/USDC minting (bullish signal)
- Detect burning events (supply contraction)
- Monitor algorithmic stablecoins for depeg risk
- Track stablecoin dominance shifts

### Pricing

**$0.002 per stablecoin** (PPE). Scanning top 100 costs ~$0.20.

### Input

```json
{
  "topN": 50,
  "depegThresholdBps": 50,
  "mechanisms": ["fiat", "crypto", "algorithmic"]
}
```

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `topN` | integer | `50` | Number of stablecoins to track (by market cap) |
| `depegThresholdBps` | integer | `50` | Basis points deviation to flag as depegged |
| `mechanisms` | array | all | Filter by mechanism type |

### Example output

```json
{
  "symbol": "USDT",
  "circulating_usd": 110000000000,
  "change_24h_pct": 0.8,
  "peg_deviation_bps": 3,
  "is_depegged": false,
  "mechanism": "fiat"
}
```

### Data source

[DefiLlama Stablecoins API](https://stablecoins.llama.fi) — free, no auth required.

# Actor input Schema

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

Scan only the top N stablecoins by market cap. 0 = all (400+).

## `depegThresholdBps` (type: `integer`):

Flag as depegged if price deviates more than this many basis points from $1.00. Default 50 bps = $0.005.

## `filterSymbols` (type: `array`):

Only return specific stablecoin symbols. E.g. \["USDT", "USDC", "DAI"]. Leave empty for all.

## `filterMechanism` (type: `string`):

Only return stablecoins of this mechanism type: fiat, crypto, algorithmic, hybrid.

## Actor input object example

```json
{
  "topN": 100,
  "depegThresholdBps": 50,
  "filterSymbols": [],
  "filterMechanism": ""
}
```

# 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.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
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/stablecoin-supply-monitor").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();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("gochujang/stablecoin-supply-monitor").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{}' |
apify call gochujang/stablecoin-supply-monitor --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,gochujang/stablecoin-supply-monitor"
        }
    }
}

```

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).
