We recommend using the TypeScript SDK for the best developer experience. The SDK is fully type-safe and exports all up-to-date types automatically.
If you’re using fetch directly and need type definitions, you can import them from the SDK or copy the definitions below.

​
Importing from the SDK

The @usemarble/sdk package exports all TypeScript types:
bash npm npm install @usemarble/sdk bash pnpm pnpm add @usemarble/sdk bash yarn yarn add @usemarble/sdk bash bun bun add @usemarble/sdk 
import type { Post, Category, Tag, Author, Pagination } from "@usemarble/sdk";

// Use with fetch
const response = await fetch("https://api.marblecms.com/v1/posts", {
  headers: { Authorization: process.env.MARBLE_API_KEY },
});
const data: { posts: Post[]; pagination: Pagination } = await response.json();

​
Type Definitions

If you prefer to copy the types directly into your project, here are the complete type definitions: 
export type Post = {
  id: string;
  slug: string;
  title: string;
  content: string;
  featured: boolean;
  description: string;
  coverImage: string;
  publishedAt: Date;
  updatedAt: Date;
  authors: Author[];
  category: Omit<Category, "count">;
  tags: Omit<Tag, "count">[];
};

export type Pagination = {
  limit: number;
  currentPage: number;
  nextPage: number | null;
  previousPage: number | null;
  totalItems: number;
  totalPages: number;
};

export type MarblePostListResponse = {
  posts: Post[];
  pagination: Pagination;
};

export type MarblePostResponse = {
  post: Post;
};

export type Tag = {
  id: string;
  name: string;
  slug: string;
  description: string | null;
  count: {
    posts: number;
  };
};
export type MarbleTagResponse = {
  tag: Tag;
};

export type MarbleTagListResponse = {
  tags: Tag[];
  pagination: Pagination;
};

export type Category = {
  id: string;
  name: string;
  slug: string;
  description: string | null;
  count: {
    posts: number;
  };
};

export type MarbleCategoryResponse = {
  category: Category;
};

export type MarbleCategoryListResponse = {
  categories: Category[];
  pagination: Pagination;
};

export type Author = {
  id: string;
  name: string;
  slug: string;
  image: string | null;
  bio: string | null;
  role: string | null;
  socials: Social[];
};

export type Social = {
  url: string;
  platform: SocialPlatform;
};

export type SocialPlatform =
  | "x"
  | "github"
  | "facebook"
  | "instagram"
  | "youtube"
  | "tiktok"
  | "linkedin"
  | "website"
  | "onlyfans"
  | "discord"
  | "bluesky";

export type MarbleAuthorResponse = {
  author: Author;
};

export type MarbleAuthorListResponse = {
  authors: Author[];
  pagination: Pagination;
};
Copy these type definitions into a types/marble.ts file in your project. If you prefer a published package, use the official SDK that exports these types.

​
NPM package

The official @usemarble/sdk package exports all TypeScript types shown on this page. Installing the package avoids copying the type definitions into multiple projects. To install the package run:
bash npm npm install @usemarble/sdk bash yarn yarn add @usemarble/sdk bash pnpm pnpm add @usemarble/sdk bash bun bun add @usemarble/sdk
You can import the types like this: 
import type { Post, Category, Tag, Author } from "@usemarble/sdk";
The package will be kept up-to-date with the API types.

​
Zod Schemas

For runtime validation, you can also create Zod schemas for your data: 
import { z } from "zod";

const PostSchema = z.object({
  id: z.string(),
  slug: z.string(),
  title: z.string(),
  content: z.string(),
  featured: z.boolean(),
  description: z.string(),
  coverImage: z.string().url(),
  publishedAt: z.coerce.date(),
  updatedAt: z.coerce.date(),
  authors: z.array(
    z.object({
      id: z.string(),
      name: z.string(),
      slug: z.string(),
      image: z.string().nullable(),
      bio: z.string().nullable(),
      role: z.string().nullable(),
      socials: z.array(SocialSchema),
    })
  ),
  category: z.object({
    id: z.string(),
    slug: z.string(),
    name: z.string(),
    description: z.string().nullable(),
  }),
  tags: z.array(
    z.object({
      id: z.string(),
      slug: z.string(),
      name: z.string(),
      description: z.string().nullable(),
    })
  ),
});

const PaginationSchema = z.object({
  limit: z.number(),
  currentPage: z.number(),
  nextPage: z.number().nullable(),
  previousPage: z.number().nullable(),
  totalItems: z.number(),
  totalPages: z.number(),
});

export const SocialSchema = z.object({
  url: z.string(),
  platform: SocialPlatformSchema,
});

export const SocialPlatformSchema = z.enum([
  "x",
  "github",
  "facebook",
  "instagram",
  "youtube",
  "tiktok",
  "linkedin",
  "website",
  "onlyfans",
  "discord",
  "bluesky",
]);
