GraphQL

GraphQL is a query language for APIs and a runtime for fulfilling those queries with existing data. Developed by Facebook in 2012 and open-sourced in 2015, GraphQL provides a complete and understandable description of the data in an API, gives clients the power to ask for exactly what they need, and enables powerful developer tools. It is maintained by the GraphQL Foundation under the Linux Foundation.

GraphQL is profiled on the APIs.io network. Tagged areas include Data Fetching, GraphQL, Query Language, and Specification.

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

GraphQL’s developer surface includes developer portal, documentation, getting-started guide, engineering blog, and 8 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/graphql: open an issue to ask a question, or submit a pull request to add artifacts.
