# App pricing reference

> Configure flat tool prices, beneficiary wallets, and outcome fees for an App.

Add `<app>.pricing.toml` beside your App manifest to define what your App
charges. Replace `<app>` with the App name used by your manifest.

If the file is missing, every App tool remains free. If the file is malformed
or invalid, Aomi refuses to load the App.

## Complete example

```toml theme={null}
version = 1

[[beneficiaries]]
name = "treasury"
type = "evm_address"
chain = "eip155:8453"
value = "0x1234567890abcdef1234567890abcdef12345678"

[resources.get_idle_assets]
pricing = { flat = 100 }
beneficiary = "treasury"

[resources.propose_trade]
pricing = { flat = 250 }
beneficiary = "treasury"

[[outcome]]
effect = "flow"
bps = 30
beneficiary = "treasury"
```

In this example, `get_idle_assets` costs `$1.00` and `propose_trade` costs
`$2.50` after a successful call. The outcome rule charges 0.30% of a supported
transaction flow.

## Top-level fields

| Field           | Type    | Required | Description                                       |
| --------------- | ------- | -------- | ------------------------------------------------- |
| `version`       | integer | Yes      | Pricing schema version. The current value is `1`. |
| `beneficiaries` | array   | No       | Wallets that can receive App revenue.             |
| `resources`     | table   | No       | Flat prices for App tools.                        |
| `outcome`       | array   | No       | Percentage fees for supported transaction flows.  |

## Beneficiaries

Each `[[beneficiaries]]` block defines one payment recipient.

| Field   | Type   | Required | Description                                      |
| ------- | ------ | -------- | ------------------------------------------------ |
| `name`  | string | Yes      | Local name referenced by tool and outcome rules. |
| `type`  | string | Yes      | Recipient type. Use `evm_address`.               |
| `chain` | string | Yes      | CAIP-2 chain identifier, such as `eip155:8453`.  |
| `value` | string | Yes      | Valid 20-byte EVM address.                       |

A rule that references a missing beneficiary is invalid.

## Resource pricing

Add one `[resources.<tool>]` table for each priced tool.

```toml theme={null}
[resources.get_quote]
pricing = { flat = 50 }
beneficiary = "treasury"
```

| Field          | Type   | Required | Description                                                            |
| -------------- | ------ | -------- | ---------------------------------------------------------------------- |
| `pricing.flat` | number | Yes      | Price in Aomi credits. Must be finite and zero or greater.             |
| `beneficiary`  | string | No       | Name from `[[beneficiaries]]`. Use it to route revenue to that wallet. |

The resource key must exactly match a tool name declared by the App. Aomi
binds the price to that App and tool. A pricing file cannot change the price of
another App's tool.

The current schema supports flat prices only. One credit equals `$0.01`.

Aomi charges the price only when the tool returns successfully.

## Outcome pricing

Add an `[[outcome]]` block to charge a percentage of a supported transaction
flow.

```toml theme={null}
[[outcome]]
effect = "flow"
bps = 30
beneficiary = "treasury"
```

| Field         | Type    | Required | Description                                            |
| ------------- | ------- | -------- | ------------------------------------------------------ |
| `effect`      | string  | Yes      | Use `flow`.                                            |
| `bps`         | integer | Yes      | Fee in basis points. Valid range: `1` through `10000`. |
| `beneficiary` | string  | Yes      | Name from `[[beneficiaries]]`.                         |

One basis point is 0.01%. A value of `30` charges 0.30%. Aomi calculates the
fee from the asset amount in base units and drops values that round down to
zero.

Outcome fees apply only when the transaction exposes a supported input flow.
Aomi adds the fee to the same smart-account transaction as the requested
action.

## Validation errors

Aomi refuses to load the App when the pricing file contains any of these
problems:

* An unsupported `version`
* Malformed TOML or an unknown field inside `pricing`
* A negative, infinite, or non-numeric flat price
* A resource key that does not match an App tool
* A missing beneficiary reference
* An unsupported beneficiary type or invalid EVM address
* An outcome fee outside the valid basis-point range

Correct the file and build the App again.
