Makani *

Makani was an Alphabet (Google X) moonshot developing airborne wind energy — "energy kites" that flew in crosswind loops to generate electricity and sent power to the grid down a tether. Backed within Alphabet and partnered with Shell, Makani wound down in 2020 after roughly 13 years of development. On closure the team open-sourced its full flight-simulation, autopilot controller, visualization, and avionics software stack under Apache-2.0 and published the Energy Kite Collection of technical reports, designs, and flight logs. Makani has no commercial or developer API surface; this API Evangelist profile tracks the company for network completeness.

Makani * is profiled on the APIs.io network. Tagged areas include Company, Frontier Tech, Renewable Energy, Wind Energy, and Airborne Wind.

Makani *’s developer surface includes documentation and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities 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.

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/. This rating is computed from github.com/api-evangelist/makani: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
