Submit an entity (business) participant to the zerohash ecosystem. Use this to onboard a legal entity — corporation, LLC, partnership, sole proprietorship, non-profit, trust/estate, and so on — along with its control persons and beneficial owners. zerohash runs the required business verification (KYB), identity, and compliance screening and returns a participant_code that identifies the entity across all other endpoints.

Your platform must be configured for this endpoint before use. Contact us for more information.

The variants below are sample requests, not rigid schemas. They illustrate common entity types and regions so you can start from the closest match — the exact fields you send depend on your platform configuration, region, and entity type. See the all-accepted-fields reference for the full superset this endpoint accepts.

💡 Use the Examples dropdown on the request body to load a ready-made payload for an entity type.
