How do I validate EU EORI numbers in an AI agent?

Steps

1. Install the Strale Python SDK, straleio.
2. Create the client with your API key.
3. Call eori-validate with the EORI number.
4. Read the result: validity, country and, when the register has it, the trader name.

The solution

# pip install straleio
from straleio import Strale, DoRequest

strale = Strale(api_key="sk_live_YOUR_KEY")

result = strale.do(DoRequest(
    capability_slug="eori-validate",
    inputs={"eori": "SE5560360793"},
    max_price_cents=20,
))

print(f"Valid: {result.output['valid']}")
print(f"Country: {result.output['country_code']}")
print(f"Trader name: {result.output.get('trader_name', 'N/A')}")

How it works

An EORI (Economic Operators Registration and Identification) number identifies a business in EU customs declarations. The tool checks the number against the European Commission's EORI validation system.

The answer holds the validity, the country code and, where the register has a record, the trader's name. The register can be slow or return no trader details for a number that is valid, so treat trader_name as best effort.
