W3C develops web standards and guidelines to ensure the long-term growth of the Web, focusing on accessibility, internationalization, privacy, and security. W3C specifications include HTML, CSS, XML, SVG, WebAssembly, ARIA, WCAG, JSON-LD, Verifiable Credentials, and hundreds of other foundational web technologies. W3C operates through Working Groups, Interest Groups, and Community Groups that develop specifications through a consensus-based process, resulting in W3C Recommendations. image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - Accessibility - Standards - Web - Web Standards created: '2025-08-25' modified: '2026-05-03' specificationVersion: '0.19' type: Index access: 3rd-Party position: Consumer apis: - aid: w3c:w3c-api name: W3C API description: >- The W3C API provides programmatic access to W3C data including specifications, working groups, editors, translations, and affiliations.
