# Read Agent Books

> How to read your Zetta Agent Books.

Agent Books show the financial state of an attributed agent.

## What Agent Books may include

* revenue
* expenses
* net flow
* treasury balance
* wallet roles
* confidence labels
* Luca verdict

## Read the confidence, not just the number

Every financial number carries a confidence label. A `$50,000` revenue with **Low** confidence is not the same claim as one with **High** confidence.

## Missing is not zero

If a value is unavailable, it should be shown as **Missing**, not `$0.00`.

See [What Zetta Does Not Claim](/trust/what-zetta-does-not-claim).

## If books are missing

If your profile has no books, it usually means:

* no manifest has been submitted
* wallets are not books-eligible
* data has not been indexed yet
* review is still pending

Missing books does not mean the agent has no activity. It means Zetta does not have enough verified attribution.
