<!-- Source: https://docs.actuallycare.com/tools/pl-statements/categorize_expense -->

Predict the expense category for a single ad-hoc expense input (description + optional vendor + optional amount). Returns category, subcategory, confidence (0–1), and the source of the prediction (per-user vendor map, platform-wide vendor map, keyword rules, or none). NOT a write — does not record the expense.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `description` | string | No | Free-text description of the expense (required if vendor not given). |
| `vendor` | string | No | Vendor or payee name. Strongest signal for the categorizer. |
| `amount_cents` | integer | No | Amount in cents. Optional — used as a tie-breaker but not required. · Min: 0 |

## Example prompts

- "How should I categorize a 450 dollar charge from Bay Photo Marketing?"
- "What expense category does an 89 dollar lockbox purchase from SentriLock fall under?"
