Yoast is the maker of the world's most popular WordPress SEO plugin, active on over 13 million sites, and is part of Newfold Digital. Yoast provides developer APIs for integrating SEO metadata, structured data (Schema.org), meta tags, sitemaps, and SEO analysis into headless WordPress sites and third-party platforms. Most of that surface ships as plugin code and runs on the customer's own WordPress install: the Yoast REST API (/wp-json/yoast/v1/get_head plus yoast_head_json on WP posts and pages), the Schema Aggregator API that emits a site's whole Schema.org graph as JSON-L, the Surfaces, Metadata and Schema PHP APIs, and — since Yoast SEO 27.5 — three read-only WordPress Abilities that hand SEO, readability and inclusive-language scores to AI agents. Yoast additionally operates one hosted API of its own, the MyYoast Provisioning (Subscription) API at my.yoast.com, a partner-gated Basic Auth surface for resellers, backed by an OpenID Connect issuer with dynamic client registration, PKCE and DPoP. Key products include Yoast SEO Free, Yoast SEO Premium, Yoast SEO for Shopify, WooCommerce SEO, Local SEO, Video SEO, and News SEO.
Yoast publishes 6 APIs on the APIs.io network, including Pages API, Posts API, SEO Head API, and 3 more. Tagged areas include SEO, WordPress, Content Optimization, Schema, and Metadata.
The Yoast catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Yoast’s developer surface includes documentation, engineering blog, pricing, API reference, getting-started guide, support, signup flow, and 48 more developer resources.
