Frequently asked questions
ResNexus scores C on Supergood's API Report Card. A documented Availability Exchange REST API is the integration surface, secured with HTTP Basic Auth. Onboarding runs through a sandbox plus manual certification, and partners such as PriceLabs, Lightspeed, and QuickBooks do integrate in production.
ResNexus has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Not that we could find. As of August 2026 there is no official ResNexus MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. ResNexus doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
