# Agent Books

> Readable financial statements for autonomous agents.

Agent Books are Zetta's financial statements for autonomous agents. They are generated from attributed, books-eligible wallets.

## What Agent Books show

Agent Books may include:

* operating revenue
* operating expenses
* net flow
* treasury balance
* wallet roles
* transaction count
* confidence labels
* Luca verdict
* data quality notes

## What counts as revenue

Operating revenue is not the same as gross inflow. Zetta is conservative.

Revenue may come from:

* recurring stablecoin inflows
* fee recipient activity
* settlement payments
* known counterparties
* patterns that suggest real operating activity

Every revenue number has a **source** and a **confidence** label.

See [Revenue vs gross inflow](/concepts/revenue-vs-gross-inflow).

## What does not count as revenue

Zetta does not treat these as operating revenue by default:

* token mints
* token transfers
* internal transfers
* bridge receipts
* swaps
* capital injections
* grants
* airdrops
* random inflows
* unknown activity

These may be shown separately, quarantined, or labeled as unknown.

## Expenses

Expenses may include:

* inference spend
* provider payments
* external service payments
* operational spend
* contract interaction costs
* recurring outbound payments

## Treasury

Treasury shows the agent's known holdings across attributed treasury wallets.

Treasury may be incomplete if:

* no treasury wallet is declared
* wallet roles are unclear
* balances cannot be fetched
* data is stale

## Confidence

Agent Books show confidence per metric.

| Confidence | Meaning                                           |
| ---------- | ------------------------------------------------- |
| High       | Strong attribution and clear transaction evidence |
| Medium     | Useful data, but some uncertainty remains         |
| Low        | Incomplete or weak evidence                       |
| Missing    | Required data is unavailable                      |

**Missing is not zero.** See [Confidence and verification labels](/concepts/confidence-labels).

## Luca's role

Luca explains Agent Books in plain language and answers:

* what is known
* what is missing
* what looks healthy
* what looks risky
* what needs verification

Luca must not invent missing data.
