- `httpx` (async HTTP client wrapper)
- `requests` (sync HTTP client wrapper)
- `all` (everything)

## Quick Start (Server)

```python
from fastapi import FastAPI
from fourmica_x402.http import fastapi_payment_middleware_from_config

app = FastAPI()

routes = {
    "GET /premium": {
        "accepts": {
            "scheme": "4mica-credit",
            "price": "$0.01",
            "network": "eip155:11155111",
            "payTo": "0xRecipient",
        }
    }
}

middleware = fastapi_payment_middleware_from_config(
    routes,
    tab_endpoint="https://api.example.com/payment/tab",
)

@app.middleware("http")
async def x402_mw(request, call_next):
    return await middleware(request, call_next)
```

## Quick Start (Client)

```python
from x402 import x402ClientSync
from x402.http.clients import x402_requests
from fourmica_x402.client_scheme import FourMicaEvmScheme

client = x402ClientSync()
client.register("eip155:11155111", FourMicaEvmScheme("0xYourPrivateKey"))

session = x402_requests(client)
resp = session.get("https://api.example.com/premium")
print(resp.status_code, resp.text)
```
