# Agentic Atlas — pricing

- Canonical source: https://agentic-atlas.dev/pricing.md
- Currency: USD
- Contact: hello@agentic-atlas.dev

The Agentic Atlas is free. There is one tier, it costs nothing,
and there is nothing here to buy: no plans to compare, no seats
to count, no metered usage, no trial that ends, no quote to
request.

## Plans

| Plan | Price | Billing | For | Includes |
| --- | --- | --- | --- | --- |
| Atlas | $0 | None | Anyone designing an agentic system, including commercial work | Every published pattern, the glossary, the decision records, the JSON API, and the MCP transport |

There is no second row, and nothing is held back behind one: a
reader and an agent are served the same Release, in full.

## Access

No account, no sign-up, no API key, no OAuth, no authentication
of any kind. An agent connects and calls.

- [Connect an agent](https://agentic-atlas.dev/connect): the transport, and a worked first call.
- [Consultation contract](https://agentic-atlas.dev/consult.md): the rules every call is held to.

## Usage limits

Published rather than discovered by being refused, and counted
per calling address, each window apart from the others:

- A2A `/a2a`: 300 requests per 60 seconds.
- JSON API: 300 requests per 60 seconds.
- NLWeb `/ask`: 300 requests per 60 seconds.
- Analytics count proxy: 60 requests per 60 seconds.
- The pages and the MCP transport are not rate limited.
  Throttling the transport would break a consultation in
  flight, which is the whole reason an agent is here.

Every response from a limited surface states its own window in
`RateLimit-Limit`, `RateLimit-Remaining` and `RateLimit-Reset`,
with `Retry-After` on a refusal, so a client can throttle
itself instead of waiting to be told, and names the window in
`RateLimit-Policy` (`"a2a"`, `"api"`, `"ask"`, `"count"`).

## Licence

Reading and use are welcome, including in commercial work, and
that does not change. Republication is not permitted: the Atlas
is source-available, not open source. Quote it, cite it, and
build on what it tells you — do not mirror the corpus as your
own.

## Support

Sponsorship funds the surveying and buys nothing else — no
tier, no priority, no private plates:
[github.com/sponsors/aj604](https://github.com/sponsors/aj604).
Reading and using the Atlas without paying anything is a
completely legitimate way to use it, and always will be.
