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.
Any top-level field the state does not accept is reported under warnings — those are dropped rather than rejected when you create the filing, so this is the only place they show up.
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.

Response
Validation result
True when the payload passed every compliance check
All compliance errors found, empty when valid
Non-blocking observations. Currently one entry per top-level field this jurisdiction does not accept — such a field is ignored on create rather than rejected, so this is the only place it surfaces. Empty when there is nothing to report.
