Reviewed targeted documentation, API schemas and pricing/enterprise/partner passages.

Exact current product/plan detail remains unresolved.
Separate credit and agent budgets; no arbitrary cross-product minute conversion.
Paid plan character balances differ from free allowance; no calling minutes inferred.
Free allowances and product rates are available; old changelog, bandwidth trial and speech volume controls do not establish these current billing terms.
Model/endpoint-specific pricing; current Falcon2 and Enterprise contracts must be checked separately.
LLM promotion ends October 1, 2026; quoted model/usage mix determines bill.
Buyer pays external stack providers; not all costs are invoiced by Murf.
