Cleargraph

Cleargraph was a Palo Alto, California startup building natural-language and graph-based search over data, operating under the tagline "Data Accessible through Search." It was backed by Version One Ventures and appears in the API Evangelist network as a portfolio lead. As of this enrichment pass the company is inactive - its primary domain cleargraph.com now 301-redirects off-site, its cleargraph.io website no longer resolves (connection refused), and its GitHub organization (github.com/cleargraph) was archived in April 2026 and holds only forked libraries with no first-party API, SDK, or specification. No live API, developer portal, documentation, or first-party package surface could be verified during enrichment, so no API artifacts were generated.

Cleargraph is profiled on the APIs.io network. Tagged areas include Company, Data, Search, Analytics, and Graph.

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