# Get an agent message credit attribution

Private session interface. Gives direct and total billed credits for an Agent message; run-agent tool rows include the invocation and charges from its sub-agent tree.

```http theme={"system"}
GET /api/w/{wId}/assistant/conversations/{cId}/messages/{mId}/consumption
```

Base URL: `https://app.counso.ai`

## Authentication

This operation requires a user OAuth access token in `Authorization: Bearer <token>`. A signed-in browser may use its Counso session cookie. A workspace API key does not supply user identity.

| `mId`     | path     | string | Yes      |             |

## Responses
