CTERA

CTERA operates the CTERA Intelligent Data Platform, a unified edge-to-cloud global file system and data fabric for managing unstructured file data across distributed enterprises. The platform combines secure file collaboration, cyber protection and ransomware defense, global file locking, enterprise search, data classification, and AI-readiness (InsightAI) over a single global namespace spanning edge, data center, and public cloud. CTERA is programmable through a RESTful Portal management API (uniform object namespace addressed by URIs), an official Apache-2.0 Python SDK (cterasdk), a CLI toolbox (ctools), and two official Model Context Protocol servers (mcp-ctera-core and mcp-ctera-edge) that give AI agents file-and-folder operations over the Portal and Edge Filer. CTERA was surfaced as a portfolio company of Bessemer Venture Partners.

CTERA publishes 1 API on the APIs.io network. Tagged areas include Company, Cloud, Storage, File Storage, and Global File System.

CTERA’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, training material, CLI, and 17 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/ctera: open an issue to ask a question, or submit a pull request to add artifacts.
