Prismic
AnnouncedHeadless CMS with a Slice Machine component model and REST plus GraphQL APIs, used by marketing and development teams to build content-driven web experiences with typed, schema-defined content.
Prismic has announced plans to support UCP as a participant. No public endpoint is available yet.
Prismic is a headless CMS centered on a component model called Slices. Developers define reusable content components (Slices) in code using Slice Machine, a local development tool. Each Slice has a defined schema with typed fields. Authors assemble page content by adding and configuring Slices through the Prismic editor.
The platform is designed to minimize the friction between developer-defined components and author-created content. Slice Machine generates TypeScript types from Slice schemas, so the content API returns typed data that frontend developers can work with without manual mapping. Prismic's API supports both REST (the Document API) and GraphQL for flexible content retrieval.
Prismic supports multiple languages, release scheduling, and environment-based publishing workflows. Its Custom Types cover both repeatable types (blog posts, products) and singleton types (homepage, navigation). The API returns content as Prismic rich text (a structured JSON format) alongside primitive field types.
Prismic is commonly used in composable commerce setups for editorial and marketing content alongside a headless commerce backend. A brand might use Prismic for homepage content, category pages, promotional campaigns, and blog posts while using commercetools or Shopify for product data and checkout.
For agents, Prismic's Document API is REST-based and paginated. Agents can query documents by type, filter by field values, and retrieve linked content through the "fetchLinks" parameter. The typed Slice structure makes Prismic responses machine-readable: each Slice has a "slice_type" identifier and a "primary" field group with named fields. This consistent structure means agents can implement extraction logic once per Slice type and apply it reliably across all documents. Prismic has been exploring how AI tools interact with CMS content and participates in composable commerce ecosystem discussions.
Why This Matters for UCP
Prismic provides typed, Slice-based content through a REST and GraphQL API, giving agents structured access to marketing and editorial content in composable commerce stacks without HTML parsing.
UCP Endpoint

Integration Example
// Prismic Document API for content retrieval.
// Agents query Slices and custom types from the repository.
import * as prismic from '@prismicio/client';
const client = prismic.createClient(process.env.PRISMIC_REPO_NAME, {
accessToken: process.env.PRISMIC_ACCESS_TOKEN,
});
// Fetch all product documents ordered by publication date
const products = await client.getAllByType('product', {
orderings: { field: 'document.first_publication_date', direction: 'desc' },
pageSize: 20,
});
console.log('Total products:', products.length);
// Fetch a single document by UID with linked content resolved
const landing = await client.getByUID('landing_page', 'summer-sale', {
fetchLinks: ['product.name', 'product.price', 'product.thumbnail'],
});
// Access a specific Slice type in the document
const heroSlice = landing.data.slices.find(s => s.slice_type === 'hero_banner');
console.log('Hero heading:', heroSlice?.primary.heading);Category
