Building a DeFi Yield Scanner with Python and AI

Here's the task requirement:

• Write a technical article
• 400 words, markdown
• Topic: Building a DeFi Yield Scanner with Python and AI
• Include code examples, practical tips, and call to action for AI API services
• Do NOT start with # or the title — start directly with content

So I need to start writing immediately, no title header. I need to make sure it's about 400 words. Include code snippets. Include practical tips. Include a call to action for AI API services. Use markdown formatting. Avoid starting with # or a title. Just start with the content.

Let me outline the structure:

• Opening paragraph about DeFi yield scanning
• How AI can help
• Python code example (maybe using web3.py, requests, etc.)
• Practical tips
• Call to action for AI API services
• Closing

I need to be careful about word count. Aim for ~400 words. Let's draft.

Start directly: "DeFi yield optimization has become..." etc.

Make sure to include code blocks with triple backticks. Include calls to action like "Consider using OpenAI's API" or "Google Gemini API" etc.

Let me write.

First, I'll start with the content. I'll target around 400 words. I'll count roughly as I go.

Let me draft:

"DeFi yield scanning is a critical task for investors seeking automated returns across multiple protocols. With dozens of lending platforms, liquidity pools, and yield farms, manual tracking is inefficient. Python, combined with AI, can automate data collection, risk assessment, and opportunity ranking. This article walks through building a DeFi yield scanner that leverages machine learning to predict APY trends and flag high-risk farms.

The first step is connecting to blockchain data. Using web3.py, we can query popular Ethereum-based DeFi protocols for current pool metrics. Below is a basic example that fetches the total liquidity and token price from a Uniswap V2 pair.

python
import web3
from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://mainnet.infura.io/v3/YOUR_PROJECT_ID'))

def get_pool_metrics(pair_address):
    # Uniswap V2 pair ABI minimal
    abi = [...]
    contract = w3.eth.contract(address=Web3.to_check
