Validate a corporation formation request
⚠️ Early access — This endpoint is in preview and may change in backwards-incompatible ways before it is marked stable. Avoid depending on it in production, and reach out before building on it.
Check a corporation formation payload against state compliance rules without creating a filing or business record. Returns every compliance error in one pass, so you can pre-flight a submission.
Accepts a partial or complete payload, including the same jurisdiction-specific fields as the create endpoint (extra top-level properties, plus jurisdiction_registered_agent and jurisdiction_stock_structure for state-specific fields). The formation requirements endpoint lists what a given state expects.
This checks state compliance rules only. Some field-format checks run on the create endpoint, so a payload that passes here can still be rejected when you submit it.
