Headless

Allows a headless application to retrieve extra information for a page or path, that isn't included by default in the JSON:API representation of the content object: breadcrumbs, metatags, redirects, etc.

Traditionally headless sites have to use a specialized search service like Algolia. This module allows a headless application to query your Solr index through Drupal using JSON:API.

I also looked at SolREST, but I'm not sure I like the idea of bypassing Search API, or the fact that it only has a dev release as of this writing.
