Manage OpenAPI via GitHub Demo

This is a demo repository showing how GitHub can be used to manage an API contract using an APIs.json index plus an OpenAPI definition and supporting artifacts. The API used in the demo is the APIs.io Search API, which exposes search and submission endpoints over the APIs.io index. The repository is referenced by an API Evangelist blog post on managing OpenAPI in GitHub.

Manage OpenAPI via GitHub Demo publishes 2 APIs on the APIs.io network: APIs API and Search API. Tagged areas include APIs.json, Demo, GitHub, OpenAPI, and Reference.

The Manage OpenAPI via GitHub Demo catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

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