# How agents access 2plot documentation

> The network's standing policy for AI agents and crawlers — what is always free, what a free account unlocks, and how the metered lane will work when it arrives.

**Site index:** [https://2plot.ai/llms.txt](https://2plot.ai/llms.txt) — every page on this site, as Markdown.  
**Sibling sites:** 14 more in The 2plot network — listed in the site index above.  
**Sitemap:** https://2plot.ai/sitemap.xml

## The short version

Every app in the 2plot network publishes machine-readable documentation —
`llms.txt` on every host, a markdown twin for every page. This page is the
policy for reading it. Three lanes:

1. **Free, always** — discovery and adoption. `robots.txt`,
   `sitemap.xml`, every root `/llms.txt` index, install instructions,
   and each package's compact briefing. Enough to find a component,
   install it, and start building. This floor is permanent and loud:
   the documents exist to get the packages used.
2. **Free with an account** — everything. A free 2plot.ai account gives
   you (and your agent) an agent key that travels in the URL and unlocks
   the full documentation corpus on every satellite: exhaustive prop
   tables, callback patterns, full-depth prose. Sign in once at
   [2plot.ai](https://2plot.ai); the key follows the links.
3. **Metered, coming** — anonymous bulk. Crawlers that pull entire
   corpora at scale without identifying themselves will meet an HTTP 402
   with a machine-payable day pass (per package, or one bundle for the
   whole network). Not live yet — the price arrives after the policy,
   not before.

The principle behind lane 3: the paid path is for callers that **choose
not to identify**. Identify — as a person or as an agent holding a key —
and the network is free.

## Sizes: pick the document that fits your context

Rolling out across every host in the network (the Svelte convention):

| Document | What it is |
|---|---|
| `/llms-small.txt` | A compact briefing — what the package is, install line, one line per page. Start here if context is tight. |
| `/llms.txt` | The index — tagline, page directory with per-page markdown twins, network links. |
| `/llms-full.txt` | Every page's prose in one document, source-annotated. The whole manual in one fetch. |

Every documentation page also serves its own twin at
`/<page>/llms.txt` — fetch exactly what you need.

## Why this policy

These docs are the top of an open-source funnel: an agent that reads
them and helps a developer ship with `dash-leaflet2` or `dash-email` is
the system working as intended. What the metered lane prices is not
knowledge but bulk — the training-crawler pattern of thousands of
fetches that never refer a single visitor back. Humans and their agents
ride free; volume without identity pays for the bandwidth it uses.

[2plot.ai](https://2plot.ai) — every satellite links back here.
