Mammoth Brands

Mammoth Brands is the consumer packaged goods company formerly known as Harry's Inc., renamed in April 2025 to reflect a portfolio that now spans Harry's (men's shaving and grooming), Flamingo (women's hair removal and body care), Lume and Mando (whole-body deodorant) and Coterie (modern baby care). Founded in 2013 by Jeff Raider and Andy Katz-Mayfield and still privately held, it reported $835M in 2024 revenue. It runs no developer programme and publishes no OpenAPI, but two of its brands operate on Shopify and therefore expose a live, anonymous Model Context Protocol server plus a Universal Commerce Protocol merchant profile on their own domains — a real agentic-commerce surface with no documentation portal behind it.

Mammoth Brands publishes 2 APIs on the APIs.io network. Tagged areas include Company, Consumer Packaged Goods, Retail, E-Commerce, and Personal Care.

Mammoth Brands’ developer surface includes engineering blog, support, authentication, and 14 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/harry-s: open an issue to ask a question, or submit a pull request to add artifacts.
