Fungible

Fungible Inc. was a Santa Clara, California startup founded in 2015 by Pradeep Sindhu (Juniper Networks co-founder) and Bertrand Serlet that built Data Processing Units (DPUs) — programmable microprocessors (the F1 and S1 chips plus the FS1600 NVMe storage array) designed to offload networking, storage, and security workloads from data-center CPUs. Its DPU cluster control plane ran Linux and exposed internal REST APIs for management, but Fungible never published a public developer API, developer portal, or SDK registry. Microsoft acquired the company in January 2023 (reported ~$190M), folded the team into its Azure data-center infrastructure engineering organization, and wound down the independent product line. The fungible.com domain no longer resolves and there is no live public API surface to enrich.

Fungible is profiled on the APIs.io network. Tagged areas include Company, Data Processing Unit, DPU, Semiconductors, and Data Center.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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