Slice is an online ordering and management platform built specifically for independent local pizzerias, giving small shops digital ordering, marketing, loyalty, and back-office tools that compete with large delivery marketplaces at a low flat per-order fee. For technology partners, Slice publishes a Slice Public API documented on a Stoplight developer portal, exposing pizzeria-oriented resources such as shops and orders over a RESTful HTTP interface in two versions (v1 and v2). The platform serves pizzeria owners and the partners that integrate ordering, POS, and operations into the Slice network across thousands of locations.
Slice publishes 4 APIs on the APIs.io network, including Orders API, Shops API, Shops API (Modeled), and 1 more. Tagged areas include Restaurant, Pizza, Online Ordering, Local Commerce, and Menus.
The Slice catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Slice’s developer surface includes authentication, documentation, getting-started guide, pricing, support, engineering blog, and 11 more developer resources.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
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/slice: open an issue to ask a question, or submit a pull request to add artifacts.
