A Machine-Readable Index for Your APIs

APIs.json is an open source format that API providers use to describe their API operations — like a sitemap.xml for APIs. It indexes OpenAPI specs, JSON Schema, documentation, pricing, terms of service, and more, making your APIs discoverable by APIs.io and other tools.
