# Understanding billing and credits

Credits pay for metered Rankability actions. Serena chat is free; research, content, tracking, audit, promotion, and enrichment actions can use credits.

## What uses credits

Metered actions include content generation, keyword research, tracking checks, audits, promotion data, source enrichment, and selected Serena actions. The product shows a cost or estimate before supported metered actions begin.

## What is free

* Serena chat.
* Initial client knowledge setup.
* Cached keyword results where the product labels them free.
* Your organization’s first Autopilot draft.
* Your organization’s first GSC keyword import.
* Your organization’s first guided plan and First Win flow where the product marks them complimentary.

## Included credits

| Public plan | Included credits |
| ----------- | ---------------- |
| Solo        | 10,000           |
| Core        | 30,000           |
| Team        | 75,000           |
| Agency      | 200,000          |

Seat and client limits vary by plan. Agency has unlimited seats and clients; do not assume that every plan does.

## Usage categories

The billing view groups usage under current product areas including Copywriter, Reporter, Researcher, and Serena. A transaction’s description and operation provide the most specific explanation.

## Reservations and failures

Some operations reserve credits at the start and finalize them on success. Failure behavior depends on the operation. Autopilot is charged once it produces a usable draft, even if a later optimization, fact, or image step fails.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.rankability.com/account-and-settings/understanding-billing-and-credits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
