`peppol_lookup`	Check whether a company can receive e-invoices over Peppol. Accepts a Peppol ID (e.g. 0208:0123456749), a VAT number (e.g. BE0123456749, NL...B01) or a Belgian enterprise number. Returns each matching participant ID, whether it is registered, whether it accepts Peppol BIS invoices, and name/country
