Summer 2

SummerOS (formerly reached at gosummer.com, which now 308-redirects to summeros.com) is an AI-driven asset-intelligence platform for short-term rental operators, owners, investors, and property managers. It provides professional-grade revenue forecasting, competitive market intelligence, and portfolio-wide performance analytics, plus an AI assistant (Sunny AI), so short-term rental teams can make data-driven pricing and investment decisions instead of relying on spreadsheets. It connects to property-management systems (Guesty, Hospitable, Streamline, Track) rather than exposing a public developer API. Surfaced as a QED Investors portfolio lead and enriched from its live public surface.

Summer 2 is profiled on the APIs.io network. Tagged areas include Company, Short-Term Rental, Vacation Rental, Property Management, and Analytics.

Summer 2’s developer surface includes documentation, support, pricing, signup flow, and 4 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/summer-2: open an issue to ask a question, or submit a pull request to add artifacts.
