Every column, including contact, company and demographic fields. The most expensive tier.

Bills the resolution_full_profile meter. The route fixes both the price and the field set, so what a call costs is legible before you make it.

Selecting a field above this tier is rejected with a 400 naming the field and the tier that carries it, rather than being silently dropped or silently billed higher. Call this tier's /schema route to see exactly which fields it admits: the allowed set is derived from the event schema and the billing catalogue, so a field that becomes billable leaves the cheaper tiers automatically.
