`lookup_participant`

Pack: peppol · Endpoint: https://gateway.pipeworx.io/peppol/mcp

Check whether a company is registered on the Peppol e-invoicing network and list every document type it accepts. Resolves the participant identifier through the Peppol SML (DNS/BDXL) to its SMP, then reads the SMP ServiceGroup — the authoritative registration check, keyless, no Peppol membership needed. Returns registered=false with the reason when the identifier has no SML record. Use search_participants first if you have a company name rather than an identifier.

Parameters

Name	Type	Required	Description
`participantId`	string	yes	Peppol participant identifier as “{schemeCode}:{value}”, e.g. “0208:1021916675” (Belgian company number), “0192:989995278” (Norwegian org number), “0088:7300010000001” (GLN). The leading 4-digit schemeCode is an ICD code and is part of the identifier. A bare VAT/org number without it will not resolve — find the right form with search_participants.
`scheme`	string	no	Identifier scheme. Effectively always the default “iso6523-actorid-upis”; only override for a non-standard network.
`environment`	string	no	”production” (default) queries the live Peppol network. “test” queries the pilot SML (acc.edelivery.tech.ec.europa.eu).
