Ask a supplier for the data points only they know. A request is a password-less, expiring link: the supplier opens /u/{token} on the public passport host, enters the fields you asked for or uploads documents, and you receive supplier.submitted. Nothing reaches your model until you accept it. See the supplier data guide.
Supplier requests (supplier_requests) are included in the Growth and Connected plans; on Free and Starter these calls answer 402 plan_upgrade_required.
Personalise the samples. Paste a test key and every snippet uses it — and your own model and passport ids.
