Data freshness varies by provider — some cache for 24h, others hit SAT on-demand. For loan origination I'd go with a provider that does live lookups, even if slightly slower.

btw does anyone have experience with rfc business verification APIs? trying to build a quick check in our loan origination system — before we lend to a company we want to confirm their RFC is legit and active with SAT.
the flow is simple: we get the RFC from the loan application, hit an API, and either get a green light (RFC valid, business active) or a red flag. we don't need tons of details, just enough to know the business actually exists in SAT's registry.
worried about data freshness — SAT updates their registry periodically but not always in real time. how stale can RFC business verification data be from third-party providers? and is there usually a webhook or refresh option to get the latest data?
