HTTPX: The Modern HTTP Client Every Python Developer Should Use in 2026 — HTTPX has become the go-to HTTP library, replacing requests in most new projects thanks to native async support, HTTP/2, better error handling, and excellent type hints.
1. Installation
uv add httpx
2. Sync Usage (Simple as requests)
import httpx
response = httpx.get("https://api.github.com")
print(response.json())
# With timeout and error handling
try:
r = httpx.get("https://api.example.com/data", timeout=10.0)
r.raise_for_status()
except httpx.RequestError as exc:
print(f"Request failed: {exc}")
3. Async Usage (Recommended for FastAPI)
import httpx
import asyncio
async def fetch_data():
async with httpx.AsyncClient(timeout=10.0) as client:
response = await client.get("https://api.example.com")
return response.json()
# In FastAPI endpoint
@app.get("/data")
async def get_data():
data = await fetch_data()
return data
4. Advanced Features
- HTTP/2 & HTTP/3 support
- Automatic retries with
httpx.Retry - Client-side caching
- Beautiful JSON handling
- Perfect integration with Pydantic
Conclusion
In 2026, use HTTPX for all HTTP needs — sync or async. It’s faster, more reliable, and future-proof compared to the classic requests library.
