Introduction

Create, update, and publish projects from your own code.

What the API Is For

The API does from code what Claude does in a session: it creates projects, updates them, and publishes them. A project can be anything that runs in a browser, like a website, app, dashboard, or game. Manifest hosts it, with staging, HTTPS, and custom domains.

For example, you could:

• Publish at scale, like a page for every product, location, or event.
• Give your customers projects, like a help center or portal for each one.
• Publish from your own tools, like a content system or a build pipeline.

Your API key also reaches the projects you already have.

How It Works

1. Create a project, tagged with your own ID so you can find it again.
2. Send updates: a full build, or just the files that changed. Updates land on staging.
3. Check staging, a separate address each project has for checking changes.
4. Promote, so the exact version you checked goes live.
5. Add a domain, if you want one, like help.example.com.

Each publish creates a deployment, one saved version of the project. Manifest keeps recent ones, so a Pro project can roll back.

Both addresses are public, but staging is kept out of search results. It's for checking a change before visitors see it on production, not for keeping it private.

The Quickstart runs through all of this in a few minutes.

Ways to Update

• Upload a build. Zip your project's files and upload them. Any static build works, from the Manifest framework or any other. See Publish.
• Change files. Send only the files that changed: pages, data, settings, styles, or images. See Edit.
• Use the docs template. Send Markdown pages and get a documentation site, with no build of your own. See Docs Template.

What's Included

Every Manifest account can use the API. Create a key on the dashboard's API page; see Authentication. No account yet? Signing in to the dashboard creates a free one.

Projects your key creates are ordinary Manifest projects. They show in your dashboard and in Claude, and can be upgraded to Pro there.

Each project keeps its own plan, so a Pro feature such as rollback needs that project on Pro. An Enterprise account's keys reach only the projects that account creates. Rate limits and storage caps are on Limits.

Base URL

All requests go to one versioned base URL:

https://api.manifestx.dev/v1

Only /v1 paths exist on this host.

Conventions

• JSON. Requests and responses are JSON.
• Bearer key. Every request sends Authorization: Bearer <key>. See Authentication.
• Server only. Call the API from your server. Browsers are refused.
• Timestamps are Unix seconds, like 1760140800.
• Ids start with a prefix: acct_ for accounts, proj_ for projects, dep_ for deployments.
• request_id is on every response. Quote it when you contact Manifest.
• Safe retries. Every request that changes something can be retried safely. See Idempotency.
