Validate an LLC 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 an LLC 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 for state-specific registered-agent 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.
