Nuclino

Nuclino is a unified team workspace that combines wikis, docs, and project management into one collaborative platform. Its REST API enables developers to build integrations and automate tasks by programmatically managing items, collections, workspaces, teams, users, fields, and files using Markdown content. The API covers the full content lifecycle — create, read, update, delete, and search — making it possible to sync knowledge bases with external systems, trigger content updates from CI/CD pipelines, and build custom tooling on top of team documentation.

Nuclino publishes 6 APIs on the APIs.io network, including Collections API, Files API, Items API, and 3 more. Tagged areas include Knowledge-Management, Team Workspace, Documentation, Wiki, and Collaboration.

The Nuclino catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Nuclino’s developer surface includes authentication, documentation, pricing, engineering blog, signup flow, and 12 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/nuclino: open an issue to ask a question, or submit a pull request to add artifacts.
