## 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

## DeFi Yield Monitor

Track lending and borrowing yields across major DeFi protocols. Built for AI agents, yield optimizers, and portfolio managers.

### Features

- **6 protocols**: Aave V3, Compound V3, Morpho Blue, Spark, Euler V2, Venus V4
- **6 chains**: Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche
- **Configurable assets**: USDC, USDT, WETH, WBTC, DAI, MATIC, AVAX
- **Supply & borrow APRs**: both directions captured per market
- **APR alerts**: webhook notifications when supply APR changes more than X%
- **TVL filter**: only track markets above a minimum TVL (avoid illiquid pools)
- **Utilization rate**: included for lending protocol analysis

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `chains` | array | `["ethereum","base","arbitrum","optimism"]` | Chains to monitor |
| `protocols` | array | `["aave","compound","morpho","spark"]` | Protocols to track |
| `assets` | array | `["USDC","USDT","WETH","WBTC","DAI"]` | Assets to track |
| `maxRuns` | int | `1` | Max checks (default 1 = run once and finish; set higher for continuous monitoring) |
| `intervalSeconds` | int | `600` | Check interval (60s - 3600s) |
| `webhookUrl` | string | — | Webhook URL for APR alerts |
| `aprChangeThreshold` | number | `20.0` | % APR change to trigger alert |
| `minTvlUsd` | int | `1000000` | Minimum TVL (USD) to include market |

### Example Input

```json
{
  "chains": ["ethereum", "base", "arbitrum", "optimism"],
  "protocols": ["aave", "compound", "morpho", "spark"],
  "assets": ["USDC", "USDT", "WETH", "WBTC", "DAI"],
  "intervalSeconds": 600,
  "minTvlUsd": 1000000

```

### Output (dataset)

```json
{
  "timestamp": "2026-08-06T01:48:22.643Z",
  "chain": "ethereum",
  "protocol": "aave",
  "asset": "USDC",
  "supply_apr": 3.25,
  "borrow_apr": 4.85,
  "tvl_usd": 1250000000,
  "utilization_rate": 68.5,
  "market_address": "0x..."
}
```

### Use Cases

- **AI agents**: find best yield opportunities programmatically

- **Risk managers**: track utilization rates across lending markets
- **Research**: historical yield data for DeFi analysis

### Pricing

Free for demo runs. Production runs billed per Apify usage units.

# 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 = {
    "chains": [
        "ethereum",
        "base",
        "arbitrum",
        "optimism"
    ],

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,yunaremaia/defi-yield-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).
