Mirror
Platform · this deep dive is built from the official pages of the platform itself and of the tools that support it.
Overview
Mirror was conceived as a publishing platform on the blockchain: texts were stored on-chain, and readers could support authors with cryptocurrency. There is no longer a standalone platform under that name — the address mirror.xyz leads to a different service, Paragraph.
This is not a guess. In May 2024 the head of Paragraph announced that Paragraph was taking Mirror into its ownership and raising 5 million dollars from Union Square Ventures and Coinbase Ventures, with Mirror's founder Denis Nazarov staying on as an adviser. In September 2025 the shutdown followed: “we are winding Mirror down over roughly a month; if you have ever written on Mirror, your posts and subscribers will be moved to Paragraph automatically, and readers coming to your blog on Mirror will be redirected to the new address; no action is required from you”.
So what follows is about Paragraph — the service that inherited Mirror's audience. It now describes itself not as a blockchain publishing house but as “a media engine for early-stage startups”: an AI-based agent turns a company's materials into posts, newsletters, social media campaigns and landing pages, and a human approves them.
Who's here
The language of the interface and documentation is English (home page).
The platform says plainly whom the service is addressed to in its description of the plans. The entry plan is called “for founders and small teams testing Paragraph on real publishing work”, and the next one “for startups for which owned media and launches are becoming a permanent way to grow”. That is, the target audience has shifted from independent authors to company marketing, and this is worth keeping in mind when choosing a platform for a personal blog.
Mirror's legacy has stayed in the product: the cryptocurrency part works. In July 2025 the platform launched “coins” under posts, explaining that it had deliberately moved away from a speculative framing — “support” instead of “buy”, “swap” instead of “sell”, three ready-made contribution levels instead of choosing a number of coins, and a popularity indicator instead of a post's market capitalization.
Getting started
Registration is free and requires no review: the home page has a “start for free” button, and the documentation promises that the quickstart is “create an account, get to know the agent and publish your first post”.
What the free plan gives is described without tricks: a permanent home for your site, posts and subscribers; a hosted site; subscriber collection; 500 agent credits a month; limited access to the API and MCP. The same page says: “the free plan really is free, and your work stays yours; there is no time limit and no pressure to move to a paid plan”.
Migration from another platform has its own documentation section — “import your posts and subscribers” — and on the higher plan help from the team with migration is promised.
What you can publish
The main format is a post with a newsletter: the documentation describes the set as an editor, newsletters, your site, custom domains and SEO. Every author is given a site, a newsletter and a subscriber list that belong to them.
On the free plan the platform promises a site with an unlimited number of posts, views and traffic (this condition is named in the description of the entry paid plan).
There is a link to the terms of use in the blog footer.
How to grow
The platform has two growth mechanisms, and it describes both itself.
Distribution by the agent. The entry plan includes publishing to X straight from Paragraph and recurring scheduled workflows; the documentation gives a separate section to subscribers, distribution and analytics. Extended analytics is available only on the higher plan: “advanced analytics” is named as its distinguishing feature.
Coins as a visibility mechanism. The platform links financial support to inclusion in a selection directly: “we have shipped a new Explore page, where the most supported posts rise to the top… support with coins instantly raises a post's visibility”. This is a rare case of a platform explaining itself that the feed is ranked not by an algorithm but by readers' money: “not because an algorithm decided so, but because real people did”.
Paragraph has no ad manager of its own.
Path to monetization
The way of earning that the platform describes in most detail is coins. Their logic: a reader supports a particular post, the author receives income, and the post rises in the selection. The platform also lists other tools that appeared after the merger with Mirror: post coins, “remixes” (a reply to a post that shares in the growth of the overall discussion) and author coins — support not for an individual post but for the author themselves.
The second source of income in the platform's description is the sale of digital goods, including to machines: a blog post is titled “Your work, paid for by agents” and promises the sale of anything digital “to people and agents”.
It is important to understand the flip side: earnings here come from readers, while the platform itself costs the author money. The plans are named plainly: free — 0 dollars and 500 credits a month; Starter — 20 dollars a month or 16 dollars when paid annually (192 dollars a year), 1,500 credits; Growth — 100 dollars a month or 80 when paid annually (960 dollars a year), 8,500 credits; Scale — 200 dollars a month or 160 when paid annually (1,920 dollars a year), 17,500 credits. Annual payment, as stated in the same place, saves 20%.
The documentation explains what credits are honestly: credits are spent on the agent's work — drafting and editing, research, recurring tasks such as a weekly digest, image generation; your own work of writing and publishing does not consume credits.
Tools and automation
The platform has programmatic access, and it is described in detail. The REST API lives at public.api.paragraph.com/api, the key is passed as a Bearer token and is created in the app under Settings → Publication → Developer. Through it you get publication data, post management, work with coins and user profiles.
The platform gives two warnings itself: the API is at the alpha stage, and breaking changes are possible until the design is final; the API is rate-limited, and to raise the limit you have to write to support.
Besides the API there is a TypeScript SDK, a command-line utility (declared suitable for work with AI agents and continuous integration pipelines), an MCP server and “agent skills” — portable instructions that teach any AI agent to work with the API, CLI or MCP. The OpenAPI specification is published in the SDK repository.
On the free plan access to the API and MCP is limited — full access to the agent starts with the paid plans.
Limits and rules

- A custom domain. Available starting from the paid Starter plan (not included in the free one).
- API. Alpha, breaking changes possible; the rate is limited.
- Visibility. The Explore selection is built on the volume of support in coins — that is, getting to the top is tied to readers' money.

Who it's for
It suits companies and startup founders who need a channel of their own: a site, a newsletter and a subscriber list that do not depend on someone else's algorithm, plus tools for automating drafts and distribution. That is exactly the job the platform sells itself for.
It suits developers: the REST API, SDK, CLI and MCP server are described openly, the key is issued in the interface, and no application has to be reviewed.
It suits authors interested in reader support through crypto coins and prepared for a post's visibility to be tied to the amount of support.
It does not suit you if Mirror is exactly what you were looking for: there is no longer a platform under that name, and the new product is built differently and costs money. It does not suit you if it matters to calculate your net income in advance: the platform does not name its commission on coins. And it does not suit projects in other languages — the whole interface and all the documentation are in English.
