Guesser

Guesser was a startup surfaced as a portfolio company of version-one-ventures and added to the API Evangelist network as a stub for enrichment. Per Version One Ventures' own portfolio listing, Guesser was acquired by Gemini in 2021 and no longer operates as an independent company. During the enrichment pass no live company website, developer portal, API documentation, OpenAPI, SDKs, or other public developer surface could be located (its likely domain guesser.io does not resolve), so no provider artifacts were produced. This profile is retained as a historical/acquired-company record.

Guesser is profiled on the APIs.io network. Tagged areas include Company, Acquired, Startup, Prediction, and Gemini.

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/guesser: open an issue to ask a question, or submit a pull request to add artifacts.
