Quick Start
Server
from mpp import Credential, Receipt
from mpp.server import Mpp
from mpp.methods.tempo import tempo, ChargeIntent
server = Mpp.create(
method=tempo(
intents={"charge": ChargeIntent()},
recipient="0x742d35Cc6634c0532925a3b844bC9e7595F8fE00",
),
)
@app.get("/paid")
@server.pay(amount="0.50")
async def handler(request, credential: Credential, receipt: Receipt):
return {"data": "...", "payer": credential.source}
Client
from mpp.client import Client
from mpp.methods.tempo import tempo, TempoAccount, ChargeIntent
account = TempoAccount.from_key("0x...")
async with Client(methods=[tempo(account=account, intents={"charge": ChargeIntent()})]) as client:
response = await client.get("https://mpp.dev/api/ping/paid")
