SCORECARD

ExistencePOORA REST API (the old POSLavu surface) is real, but its docs are gated to active merchants and approved partners.
AccessPOORNo self-serve path: ISVs apply through Lavu's integrations team, and even QuickBooks integrators are routed through Lavu directly.
CoverageGOODDocumented endpoints cover menu and modifiers, orders and checks, payments, employees, sales reporting, and inventory.
AuthPOORCredentials are a dataname, key, and token issued inside the merchant Control Panel; no OAuth or self-serve app registration.
Docs & DXPOORDocs live on a legacy admin.poslavu.com URL behind an account; only a community Ruby client exists, no first party SDKs.
StabilityMIXED
Supergood: Lavu has an API, but using it means gates, contracts, or workarounds. Ours doesn't: stable endpoints, normalized JSON, managed auth.
