req402-sdk 0.5.0

The easiest automatic analytics SDK for x402 payments

How to add it to your existing API (2 steps, < 2 minutes)

1. Install the SDK in your project terminal:

   pip install req402-sdk
   

2. Open your main API file (e.g. main.py or app.py) and add these two lines:

   from req402 import req402Middleware   # add this import
   app = FastAPI()
   app.add_middleware(req402Middleware, api_key="your_key_here")  # add this line
   

Full example of what your file should look like:

from fastapi import FastAPI
from req402 import req402Middleware   # ← new

app = FastAPI()

app.add_middleware(req402Middleware, api_key="fk_your_key_from_dashboard")  # ← new

@app.get("/")
def home():
  return {"message": "My x402 API"}

@app.post("/api/chat")
def chat():
  return {"response": "Paid response!"}
