EoriCustomsEuTradeValidation

Validate EU EORI numbers (all 27 EU states + XI Northern Ireland) live against the European Commission's official EORI validation service. Batch up to 10. Returns valid/invalid per number, request date and, where the trader consented to publication, name and address. Format pre-check so typos fail free. Use when shipping, invoicing or clearing customs with an EU trader and you must confirm its EORI number is valid in the official EU register.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
