EU Compliance Tools for AI Agents — pay per call in USDC (x402), no account

Machine-payable EU compliance APIs. An AI agent calls an endpoint, gets HTTP 402 Payment Required, pays a fraction of a cent in USDC on Base, repeats the call and receives the result. No account, no API key, no subscription, no minimum. Also available as an MCP server for Claude, Claude Code and other agent runtimes.

Tool	What it answers	Price
Agent spend bookkeeping	What did my agent spend, in EUR, with which VAT treatment? Chain → EUR (ECB rate) → CSV for accounting	$0.50
EU sanctions screening	Is this person or company on the official EU consolidated sanctions list? (AML/KYC)	$0.05
EU VAT rules engine	Place of supply, reverse charge, EN 16931 category + exemption codes for e-invoicing	$0.02
EU VAT ID validation	Live VIES register check, returns registered name and address	$0.002
IBAN validation	Checksum and country structure	$0.002
Receipt / invoice extraction	Photo or PDF → structured JSON (vendor, date, total, VAT, line items), DACH-optimised	$0.10

Every answer carries its official source and data date, so results are auditable. Sanctions data comes from the European Commission's Financial Sanctions Files and is re-indexed daily.

Quick start (Python)

pip install "x402[evm]" requests

import requests
from eth_account import Account
from x402.client import x402ClientSync
from x402.http.clients.requests import wrapRequestsWithPayment
from x402.mechanisms.evm.exact.register import register_exact_evm_client
from x402.mechanisms.evm.signers import EthAccountSigner

account = Account.from_key("0x...")          # wallet funded with USDC on Base
client = x402ClientSync()
register_exact_evm_client(client, EthAccountSigner(account), networks="eip155:8453")
session = wrapRequestsWithPayment(requests.Session(), client)

r = session.get("https://api.eucompliance.tools/x402/counterparty",
                params={"name": "Acme GmbH", "vat": "ATU12345678"})
print(r.json()["risk"])       # {'level': 'clear', 'reasons': [...], 'recommendation': '...'}

The payer needs no ETH for gas — settlement is sponsored via EIP-3009 through the Coinbase facilitator.

MCP (Claude, Claude Code, other agent runtimes)

claude mcp add --transport http eu-compliance https://mcp.eucompliance.tools/mcp

Tools: check_counterparty_eu, screen_sanctions_eu, eu_vat_rules, validate_vat, validate_iban. Payment travels in-band with the tool call (_meta); an unpaid call returns machine-readable payment requirements.

Why pay-per-call

Compliance data is needed in bursts: onboarding a supplier, booking an invoice, paying a new payee. Subscriptions price that badly for agents, and API keys require a human to sign up. With x402 an agent can settle a $0.002 call on its own within its spending policy — no contract, no onboarding.
