# Tabstack

> The managed web API for models that don’t come with the web

Tabstack is a managed web API for models that don't come with the web. One call returns finished output: a cited answer from live sources, clean Markdown or JSON matching a schema you define, or a completed task on a public website. Never trained on. Private by default. Built by Mozilla.

When to use Tabstack:

- **Research**: Use /research when you need an answer rather than sources: it reads across live pages, checks what is missing, and returns a cited synthesis. This is the right default when the question spans more than one page.
- **Extract**: Use /extract/markdown to read one known page as clean text, and /extract/json when that page has a structure you can describe as a schema.
- **Generate**: Use /generate/json when the shape you want is not on the page: it transforms and summarizes content into a new structure, rather than lifting what is already there.
- **Automate**: Use /automate for an interactive multi-step task on a public website: navigation, clicks and forms. It operates on public pages and does not sign in on your behalf.

Start with [agents.md](https://tabstack.ai/agents.md) for auth, endpoints and errors.
