Python SDK for AsterPay — EUR settlement for AI agent commerce via x402 protocol.

What is AsterPay?

AsterPay is the EUR settlement layer for AI agent commerce. Convert USDC to EUR via SEPA Instant in under 10 seconds — on Base, MiCA-compliant, and listed in the Coinbase x402 ecosystem.

Install

pip install asterpay

Quick Start

from asterpay import AsterPay

client = AsterPay()

# Get a crypto price ($0.001 USDC)
price = client.market.price("bitcoin")
print(f"BTC: ${price['price']}")

# Get EUR settlement estimate (FREE)
quote = client.settlement.estimate(amount_usdc=100)
print(f"100 USDC → {quote['eur_amount']} EUR")

# AI text summarization ($0.01 USDC)
result = client.ai.summarize("Your long article text here...")
print(result['summary'])

# Check your ASTERPAY tier (FREE)
tier = client.token.check_wallet("0xYourWallet...")
print(f"Tier: {tier['tier']} ({tier['discount']}% discount)")

LangChain Integration

pip install asterpay[langchain]

from asterpay.langchain import get_asterpay_tools
from langchain.agents import create_react_agent

# 19 tools — market data, AI, EUR settlement, crypto analytics
tools = get_asterpay_tools()
agent = create_react_agent(llm, tools)

# Or just the free tools (no x402 payment needed)
from asterpay.langchain import get_free_tools
free_tools = get_free_tools()

CrewAI Integration

pip install asterpay[crewai]

from asterpay.crewai import get_asterpay_tools
from crewai import Agent

analyst = Agent(
    role="Crypto Analyst",
    goal="Analyze market trends and settle profits to EUR",
    tools=get_asterpay_tools()
)

Both Frameworks

pip install asterpay[agents]  # installs langchain + crewai support

Async Support

from asterpay import AsyncAsterPay
import asyncio

async def main():
    async with AsyncAsterPay() as client:
        price = await client.market.price("ethereum")
        print(f"ETH: ${price['price']}")

asyncio.run(main())

EUR Settlement

AsterPay's core feature — USDC to EUR via SEPA Instant:

# 1. Get a quote
quote = client.settlement.estimate(amount_usdc=500)
print(f"500 USDC → {quote['eur_amount']} EUR (fee: {quote['fee']})")

# 2. Check Bridge provider health
health = client.settlement.bridge_health()
print(f"Bridge status: {health['status']}")

x402 Protocol

Paid endpoints use the x402 HTTP payment protocol. When a 402 response is returned, your x402-compatible wallet or agent framework handles the USDC micropayment automatically.
