Paragraph

Paragraph is a web3-native publishing and newsletter platform where writers get a website, a newsletter, an owned subscriber list, and an AI agent that drafts, distributes, and maintains their publication. It supports custom domains, Substack import, subscriber management, and onchain monetization through writer coins and post coins. Paragraph ships a full public REST API (public.api.paragraph.com), an official TypeScript SDK, a CLI, a hosted Model Context Protocol server, and published Agent Skills so developers and AI agents can manage posts, publications, subscribers, and coins programmatically. Backed by Union Square Ventures.

Paragraph publishes 10 APIs on the APIs.io network, including analytics API, auth API, coins API, and 7 more. Tagged areas include Company, Publishing, Newsletters, Web3, and Content.

Paragraph’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 28 more developer resources.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/paragraph: open an issue to ask a question, or submit a pull request to add artifacts.
