LemonBox

LemonBox (来檬) is a health-technology brand working in AI-generative personalized nutrition. Founded in 2016 in Silicon Valley, incubated at the University of Chicago Polsky Center in 2017, and accepted into Y Combinator in 2018, it entered the Chinese market that year and is now headquartered in Shanghai. LemonBox builds individualized daily vitamin and supplement packs from a three-minute FFQ (food frequency questionnaire) nutrition assessment scored by its LemonAlgo adaptive engine, then fulfills them one pack at a time (MOQ=1) through its Personalization Fulfillment Center in Hong Kong. The company reports serving more than 10 million cumulative users as of 2026 and sells both direct-to-consumer and B2B. Investors include Y Combinator and Partech. LemonBox operates a consumer web and WeChat mini-program experience and publishes no public developer API, SDK, or developer portal; its agent-facing surface is limited to a published /llms.txt and a robots.txt that explicitly allow-lists generative-AI crawlers.

LemonBox is profiled on the APIs.io network. Tagged areas include Company, Consumer, Health, Nutrition, and Supplements.

LemonBox’s developer surface includes engineering blog, FAQ, and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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/.
