Find the Best DeFi Yields with Python: A Developer's Guide

Are you looking to integrate crypto data into your Python projects? This guide shows you exactly how to do it using free public APIs — no paid subscription needed.

Why Python for Crypto?

Python is the go-to language for crypto developers because:

• 🐍 Simple, readable syntax for rapid prototyping
• 📊 Excellent data analysis libraries (pandas, numpy)
• 🔌 Easy HTTP requests with httpx/aiohttp
• 🤖 Perfect for automation and bots

Getting Started

First, install the required library:

pip install httpx

Implementation

Here's the working code:

import httpx

async def get_defi_yields(min_apy=10.0):
    async with httpx.AsyncClient() as client:
        r = await client.get("https://yields.llama.fi/pools", timeout=30)
        pools = r.json()["data"]
        high_yield = [p for p in pools
                      if p.get("apy", 0) >= min_apy
                      and p.get("tvlUsd", 0) >= 1_000_000]
        return sorted(high_yield, key=lambda x: x["apy"], reverse=True)[:10]

import asyncio
pools = asyncio.run(get_defi_yields())
for pool in pools:
    print(f"{pool['project']} | {pool['symbol']} | APY: {pool['apy']:.1f}%")

How It Works

1. Async HTTP: We use httpx.AsyncClient for non-blocking requests
2. Free API: Binance/CoinGecko public APIs require no authentication
3. Error handling: Always wrap API calls in try/except

Real-World Applications
