Spectral is one of 10 APIs that [API Linting](https://apis.io/providers/linting/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include API Linting, API Style Guide, AsyncAPI, JSONPath, and OpenAPI. The published artifact set on APIs.io includes API documentation, a getting-started guide, a GitHub repository, and a changelog.

Stoplight's flexible JSON/YAML linter for creating automated style guides, with baked-in support for OpenAPI v3.1, v3.0, v2.0, Arazzo v1.0, and AsyncAPI v2.x. Spectral is the de facto reference linter for API style guides — every other tool in this index either extends its rule grammar or competes with it directly.
