eucompliance-tools

EU compliance checks without an account. VAT IDs against the live VIES register, IBANs, sanctions lists, company registers, AI Act Article 50 — and every answer carries a signed receipt.

pip install eucompliance-tools

from eucompliance_tools import vat, iban, sanctions

vat("ATU16170006")                    # format, checksum, and the official VIES register
iban("AT611904300234573201")          # checksum, country structure, bank
sanctions("Muster Person")            # EU, UN and UK consolidated lists

No signup, no key, no card. 100 free calls a day.

Why the receipt matters

Every answer carries a signed record over its own content. Anyone can check it later — free, no account:

from eucompliance_tools import vat, verify

answer = vat("ATU16170006")
verify(answer)
# {'valid': True, 'content_unchanged': True, 'signature_valid': True, ...}

If a single field was altered after the check ran, valid is False and the verdict carries receipt_tampered. That turns a compliance result into a document you can put in a file, instead of a claim someone has to trust.

The failure codes follow the taxonomy adopted by CAAP-1, so a bookkeeping consumer can route on them directly.

What is covered

Beyond the free tier

The free tier is 100 calls a day and needs nothing. Past that there are two ways, and neither needs an account.

Pay per call in USDC (x402 on Base — the payer needs no ETH, gas is sponsored):

pip install eucompliance-tools[x402]

from eth_account import Account
from eucompliance_tools import paid

account = Account.from_key("0x…")
paid("preflight", params={"chain": "base", "to": "0x…"}, account=account)

Or a key with 100 calls included, from https://eucompliance.tools/kaufen — email in, key out, no card:

import os
os.environ["EUCOMPLIANCE_API_KEY"] = "…"

For AI Act Article 50, use the dedicated package

ai_disclosure() here is the direct call. For production use eucompliance-ai-act instead — it hooks into your existing LLM client in one line, hashes the output locally so your content never leaves your system, and attaches the disclosure to every generation:

from eucompliance_ai_act import wrap
client = wrap(OpenAI(), deployer="Muster GmbH")

Honest limits

These checks read official sources and report what those sources say at the moment you ask. VIES goes down; a register can be stale; a sanctions hit on a common name needs a human to look at it. The receipt proves what we returned and when — it does not turn a screening hit into a legal judgement.

Technical service, not legal advice.
